The Dodge Dart is a line of passenger cars produced by Dodge from the 1959 to 1976 model years in North America, with production extended to later years in various other markets.
123-401: The production Dodge Dart was introduced as a lower-priced full-size model in 1960 and 1961, but became a mid-size car for one model year for 1962, and was then reduced to a compact for two generations, from 1963 to 1976. Chrysler had first used 'Dart' name plates on two Italian styled show cars , in 1956 and 1957, before it became a Dodge model name. The Dart nameplate was resurrected for
246-443: A Dana 60 built heavy-duty axle with a 4.88 gear ratio , heavy-duty clutch , steel bellhousing, and special torque shaft and pivots. Manual transmissions were modified by removing synchronizers which lowered the chances of missed shifts . A Hurst floor-mounted shifter came standard. The automatic transmissions were the then-new Chrysler-built 727 TorqueFlite three-speed with 8-3/4 inch large stem pinion center section with
369-579: A Fiat-derived compact car that was introduced in 2012. The Dart name originally appeared on a 1956 Chrysler show car , featuring a streamlined body designed by the Italian coachbuilder Carrozzeria Ghia , that was later modified and renamed the Dart Diablo. For 1957, Ghia built Chrysler a second, visually similar show car, the Chrysler Ghia Super Dart 400. The first Dodge Darts were introduced for
492-409: A Prestolite ignition and solid core wires were also used. The cars weighed approximately 3,000 lb (1,361 kg). The cars were designed to meet street legal requirements, but due to the modifications, the cars came with disclaimers that they were not for street use, but rather "supervised acceleration trials", or drag racing. The 2-door sedan was dropped at the end of 1968 and replaced with
615-414: A countershaft (also called a layshaft ) and an output shaft . The input shaft is connected to the engine and spins at engine speed whenever the clutch is engaged. The countershaft has gears of various sizes, which are permanently meshed with the corresponding gear on the input shaft. The gears on the output shaft are also permanently meshed with a corresponding gear on the countershaft; however,
738-614: A 2-door hardtop in the Valiant line called the Scamp. It was the same car as the Swinger with a Valiant front clip. The 1970 Dart's dual tail lamps were given over to the badge-engineered Scamp , while the 1971 Dart received new smaller quad taillamps that would be used through 1973. The custom 2-door hardtop coupe became the Swinger, and the standard Swinger became the Swinger Special. Dodge gained
861-489: A 2X4-barrel Holley carburetors atop a lightweight crossram aluminum intake manifold rated at 425 hp (431 PS; 317 kW) at 5,000 rpm and a maximum torque of 490 lb⋅ft (664 N⋅m) at 4,000 rpm. A high-performance Mopar battery was moved to the trunk to free up room and improve weight distribution . Darts could be ordered with either a four-speed manual or three-speed automatic transmissions. Manual transmission equipped cars, code A-833 , featured
984-460: A 4.86 gear set, and a 2,600 rpm high speed torque converter . They were also modified with a floor-mounted Hurst shifter for manual shifting. Other features include heavy-duty rear shocks , heavy-duty radiator with a seven-blade fan, and deep groove pulleys, a high capacity oil pump , solid- lifter cam, and a roller timing chain to reduce stretch and provide more reliable performance. A transistorized dual points breaker distributor coupled with
1107-628: A carburetor anti-ice system borrowed from Canadian-market Chrysler 6-cylinder engines, and the drum brake automatic adjusters were revised for more consistent operation. At the top of the Dart performance range for 1969, there was limited availability of the 440 V8 in the Dart GTS model. The Dart was refreshed for 1970 with front and rear changes designed to bring the car closer to the design themes found in Dodge's full-size vehicles through grille and contour changes. In
1230-641: A chrome trim ring. These would remain unchanged through the 1976 model year.

1353-675: A column shifter and more practical, as the gearbox was mounted in front of the engine. The linkage for the shifter could then be positioned on top of the engine. The disadvantage is that shifting is less comfortable and usually slower to operate. Newer small cars and MPVs , like the Suzuki MR Wagon , the Fiat Multipla , the Toyota Matrix , the Pontiac Vibe , the Chrysler RT platform cars,

#17328696954981476-417: A column shifter are the ability to switch between the two most commonly used gears—second and third—without letting go of the steering wheel, and the lack of interference with passenger seating space in vehicles equipped with a bench seat . Some smaller cars in the 1950s and 1960s, such as Citroën 2CV , Renault 4 and early Renault 5 feature a shifter in the dash panel. This was cheaper to manufacture than
1599-518: A column-mounted manual shifter. Outside North America, the column-mounted shifter remained in production. All Toyota Crown and Nissan Cedric taxis in Hong Kong had the 4-speed column shift until 1999 when automatic transmissions were first offered. Since the late 1980s or early 1990s, a 5-speed column shifter has been offered in some vans sold in Asia and Europe, such as Toyota Hiace , Mitsubishi L400 and
1722-407: A conventional manual transmission, but are shifted automatically. Alternatively, there are semi-automatic transmissions . These systems are based on the design of, and are technically similar to, a conventional manual transmission. They have a gear shifter which requires the driver's input to manually change gears, but the driver is not required to engage a clutch pedal before changing gear. Instead,
1845-411: A gear while the transmission requires the driver to adjust the throttle so that the transmission is not under load, and selecting a gear requires the engine RPM to be at the exact speed that matches the road speed for the gear being selected). Most motor vehicles use a pedal to operate the clutch; except for motorcycles, which usually have a clutch lever on the left handlebar . In most vehicles with
1968-425: A gearshift without fully disengaging the clutch). Larger differences in speed between the input shaft and the gear require higher friction forces from the synchromesh components, potentially increasing their wear rate. Even in modern transmissions where all of the forward gears are in a constant-mesh configuration, often the reverse gear uses the older sliding-mesh ("crash box") configuration. This means that moving
2091-452: A light-argent (silver) paint. Demon production was substantially less than Duster's; this is reflected in higher collector car values for the Demon, especially V8 models. The 1973 model year Darts received new front styling with revised fenders, grille, header panel, and hood. Impact absorbing front bumpers were installed to comply with new federal regulations, as well as side-impact guard beams in
2214-619: A manual transmission but have added components (such as computer -controlled actuators and sensors ) which automatically control the timing and speed of the gear shifts and clutch; this design is typically called an automated manual transmission (or sometimes a clutchless manual transmission ). Contemporary manual transmissions for cars typically use five or six forward gears ratios and one reverse gear, however, transmissions with between two and seven gears have been produced at times. Transmissions for trucks and other heavy equipment often have between eight and twenty-five gears, in order to keep
2337-438: A manual transmission, the flywheel is attached to the engine's crankshaft , therefore rotating at engine speed. A clutch disc sits between the flywheel and the transmission pressure plate which is attached to the transmission input shaft, controlling whether the transmission is connected to the engine or not. The clutch pedal controls the pressure plate ( clutch engaged – the clutch pedal is not being pressed) or not connected to
2460-421: A manual transmission, the driver selects gears by manipulating a lever called a gear stick (also called a gearshift , gear lever or shifter ). In most automobiles, the gear stick is located on the floor between the driver and front passenger, but some cars have a gear stick that is mounted to the steering column or center console. The movement of the gear stick is transferred (via solid linkages or cables) to
2583-400: A mechanism is needed to stop the input shaft, such as using the synchronizer rings for fifth gear. However, some vehicles do employ a synchromesh system for the reverse gear, thus preventing possible crunching if reverse gear is selected while the input shaft is still spinning. Most transmissions include a lockout mechanism to prevent reverse gear from being accidentally selected while the car
SECTION 20
#17328696954982706-426: A new dual-plane front end contour: the center section of the grille, bumper, and leading edge of the hood were recessed from the front plane of the car. The single headlamps were placed forward of the recessed center section, defining the front plane. Park/turn lamps were set into the grille, in the corners formed by the transition area between the recessed and forward sections. With the new design, changes were made to
2829-454: A press release to Dodge dealerships . It was a promotional pitch purposed at selling drag-ready, Hemi-powered Darts. The press release stated that Dodge wanted to make a factory-built and ready drag racer out of the 68 Dart GTS hardtop for competition in class B Super Stock (drag racing) . Engineers stated the new Hemi Dart reached speeds of 130 mph (209 km/h) in less than 11 seconds and 1 ⁄ 4 mi (402 m) times in
2952-441: A switch or pressing a button on the gearshift knob or on the steering column, or automatically by momentarily lifting the foot from the accelerator with the vehicle traveling above a certain road speed. Automatic overdrives were disengaged by flooring the accelerator, and a lockout control was provided to enable the driver to disable overdrive and operate the transmission as a normal (non-overdrive) transmission. The term 'overdrive'
3075-484: A synchromesh and teeth on each side in order to lock either gear to the shaft. Unlike some other types of clutches (such as the foot-operated clutch of a manual-transmission car), a dog clutch provides non-slip coupling and is not suited to intentional slipping. In order to provide smooth gearshifts without requiring the driver to manually match the engine revs for each gearshift, most modern passenger car transmissions use 'synchromesh' (also called 'synchronizer rings') on
3198-411: A three-speed manual transmission. This transmission, along with many similar designs that it inspired, was a non-synchronous (also called sliding-mesh ) design where gear changes involved sliding the gears along their shafts so that the desired cogs became meshed. The driver was therefore required to use careful timing and throttle manipulation when shifting, so the gears would be spinning at roughly
3321-439: A typical hydraulic automatic transmission , which uses an epicyclic (planetary) design, and a hydraulic torque converter . An automatic transmission that allows the driver to control the gear selection (such as shift paddles or "+/-" positions on the gear selector) is called a manumatic transmission, and is not considered a manual transmission. Some automatic transmissions are based on the mechanical build and internal design of
3444-540: A version of Plymouth's popular Valiant-based fastback Duster which was to be named the Beaver , but when Chrysler's marketing department learned that "beaver" was CB slang for vagina , the vehicle was renamed the "Dart Demon". As was the case with previous Dodge rebadges of Plymouth Valiants, such as the 1961–1962 Lancer , sales of the Demon lagged behind those of the Duster. With optional hood scoops and blackout hood treatment,
3567-429: Is also used to describe a gear with a ratio of less than one (e.g., if the top gear of the transmission has a ratio of 0.8:1). Vehicles with a manual transmission can often be push started when the starter motor is not operational, such as when the car has a dead battery or when the starter motor itself has malfunctioned and is unable to deliver sufficient rotational energy to turn the engine over. When push-starting,
3690-427: Is connected via a pinion gear at the end of the counter/output shaft. In a modern constant-mesh manual transmission, the gear teeth are permanently in contact with each other, and dog clutches (sometimes called dog teeth ) are used to select the gear ratio for the transmission. When the dog clutches for all gears are disengaged (i.e. when the transmission is in neutral), all of the gears are able to spin freely around
3813-445: Is moving forwards. This can take the form of a collar underneath the gear knob which needs to be lifted or requiring extra force to push the gearshift lever into the plane of reverse gear. Another design of transmission that is used in older cars , trucks , and tractors , is a non-synchronous transmission (also known as a crash gearbox). Non-synchronous transmissions use a sliding-mesh (or constant-mesh, in later years) design and have

3936-404: Is used to reverse the direction in which the output shaft rotates. In many transmissions, the input and output shafts can be directly locked together (bypassing the countershaft) to create a 1:1 gear ratio which is referred to as direct-drive . In a transmission for longitudinal engined vehicles (e.g. most rear-wheel-drive cars), it is common for the input shaft and output shaft to be located on
4059-710: The Ford Fairlane . When Dodge dealers voiced their displeasure at having no true full-size car to offer, Chrysler quickly created the Dodge Custom 880 in January 1962 by putting the 1961 Dodge Polara front end assembly on a version of the 1962 Chrysler Newport body. The 1962 Dart, like the Plymouth, was on a new lightweight unibody "B" platform , featuring Chrysler's well-received "Torsion-Aire" torsion bar front suspension and asymmetric rear leaf springs. The rigidity gained through
4182-647: The Honda Element , the Honda Civic , the Daihatsu Sigra , and the Honda Avancier , may feature a manual or automatic transmission gear shifter located on the vehicle's instrument panel, similar to the mid-1950s Chryslers and Powerglide Corvairs . Console-mounted shifters are similar to floor-mounted gear shifters in that most of the ones used in modern vehicles operate on a horizontal plane and can be mounted to
4305-427: The splines on the shaft, forcing that shaft to rotate at the same speed as the gear hub. However, the clutch can move back and forth on the shaft, to either engage or disengage the splines. This movement is controlled by a selector fork that is linked to the gear lever. The fork does not rotate, so it is attached to a collar bearing on the selector. The selector is typically symmetric: it slides between two gears and has
4428-415: The stereo system or HVAC system , to help prevent accidental activation or driver confusion. More and more small cars and vans from manufacturers such as Suzuki , Honda , and Volkswagen are featuring console shifters in that they free up space on the floor for other features such as storage compartments without requiring that the gear shift be mounted on the steering column. Also, the basic location of
4551-527: The windshield wiper arms were also part of the 1968 federally mandated safety package. Chrysler's "clean air package" emission control system became standard equipment on cars sold in all 50 states. The steering linkage was revised again, as were the windshield and rear window gaskets and trim-lock strips, leaving the 1967 pieces as one-year-only items. The standard rear axle ratio was dropped from 2.93 to 2.76 with all standard-performance engines and automatic transmission . Part-throttle downshift functionality
4674-410: The 10-11 second range, although times have been reported as low as the 9-10 second range. To keep weight low, a fiberglass hood and fenders were used. The hood featured a functional intake scoop and four hood pins for full lift-off removal of the hood. Lightweight acid-dipped steel doors with thin side window glass were used. As the doors lacked a window mechanism, a strap was attached to the bottom of
4797-471: The 1948 Ferrari 166 Inter and the 1953 Alfa Romeo 1900 Super Sprint . Five-speed transmissions became widespread during the 1980s, as did the use of synchromesh on all forward gears. Six-speed manual transmissions started to emerge in high-performance vehicles in the early 1990s, such as the 1990 BMW 850i and the 1992 Ferrari 456 . The first 6-speed manual transmission was introduced in the 1967 Alfa Romeo 33 Stradale . The first 7-speed manual transmission
4920-518: The 1950s, constant-mesh manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission . Common types of automatic transmissions are the hydraulic automatic transmission (AT) and the continuously variable transmission (CVT). The automated manual transmission (AMT) and dual-clutch transmission (DCT) are internally similar to
5043-423: The 1960 model year. They were downsized large cars developed to replace Plymouths in the standard, low-priced car segment for the Dodge dealer network. Dodge dealers had been selling Plymouths since 1930, but divisional restructuring took the Plymouth brand away from the Dodge dealer network. Project planners proposed the name Dart, only to have Chrysler executives demand an expensive research program that produced

5166-512: The 1962 Lancer. The Dart remained extremely popular through the end of the Dart's production run in 1976 in comparison to the Ford Falcon and the Chevrolet Nova . Initial engine offerings were two sizes of the slant-six: a 170 cu in (2.8 L), 101 hp (75 kW) version was fitted as standard equipment, and a 225 cu in (3.7 L), 145 hp (108 kW) version
5289-492: The 2-barrel carbureted 273's 180 bhp (130 kW). At the same time the 4-barrel carbureted 273 235 bhp (175 kW) was replaced on the options list by the 275 bhp (205 kW) 4-barrel carbureted 340 cu in (5.6 L) available only in the 1968–1972 Swinger and the hottest Dart, the performance-oriented GTS models. The Dart GTS came standard with the 340 cu in (5.6 L) V8. A 300 hp (220 kW) 383 cu in (6.3 L) big-block
5412-440: The 318 cu in (5.2 L) and 361 cu in (5.9 L) V8s were also available in various configurations. Phoenix convertibles were equipped with V8 engines. Beginning mid-year, some Darts ordered with the 225 engine were equipped with the die-cast aluminum block. Darts in all series were equipped as standard with three-speed, column-shifted manual transmissions . Chrysler's pushbutton-shifted TorqueFlite automatic
5535-430: The 4.125 in (104.8 mm) stroke of the 225 crank) and connecting rods (7.006 in (178.0 mm) long vs. the 6.67 in (169 mm) rods in the 225). Nevertheless, the 225 remained an upgrade option. The 2-barrel 273 cu in (4.5 L) small-block V8 was supplanted on the option list in 1968 by a 318 cu in (5.2 L) 2-barrel engine. The 318 was rated at 230 bhp (170 kW) versus
5658-485: The American market in 1961, down from sixth place in 1960. Sales of the compact Dodge Lancer were 74,773 units compared to its Plymouth twin, the Valiant, which sold 143,078 units for the same year. The 1961 model year saw Dodge's total production drop below the slow-selling 1959 model year and almost the disastrous recession year of 1958 when Dodge faced the consequences of the poor reputation of its 1957 models. For 1962,
5781-452: The Dart lineup, beginning with the elimination of its station wagons and the base model's "170" designation. The only body styles were the 2- and 4-door sedans, the hardtop, and the convertible. The base 170 model was now badged simply as "Dart". The 270 and GT versions carried on unchanged for the most part. In late 1967, the GTS model debuted but was built in limited quantities due to its lateness in
5904-643: The Dart station wagons used the same 122 in (3,099 mm) wheelbase as the upmarket Polara wagons. The Dart line was offered in three trim levels: the basic Seneca, mid-range Pioneer, and premium Phoenix. The new Dart came standard with a new engine, the 225 cu in (3.7 L) slant-six . The 318 cu in (5.2 L) (standard equipment on certain Phoenix and Pioneer body styles) and 361 cu in (5.9 L) V8s were optional with two-barrel or four-barrel carburetors , and with single or dual exhaust. The Dodge 383 cu in (6.3 L) V8
6027-439: The Dart to surpass compacts from Ford and GM. Changes for 1968 were relatively subtle. The park and turn lights in the grille were moved slightly inboard and made round. Side marker lights were added to the front fenders and rear quarter panels , to comply with newly introduced Federal Motor Vehicle Safety Standard 108 . Shoulder harnesses (separate, this year and until 1973, from the lap belts) and non-glare matte finish on
6150-544: The Lancer's 106.5 in (2,705 mm). This longer wheelbase used the same A-body suspension of the Valiant and defunct Lancer, and would underpin all Darts from 1963 to 1976 except the 1963–1966 station wagons which used the Valiant's (106 in (2,692 mm) wheelbase) and the 1971–1976 Demon/Sport which used the Plymouth Duster 's 108 in (2,743 mm) wheelbase. The longer wheelbase gave more rear seat legroom than
6273-464: The Seneca, Pioneer, and Phoenix trim levels and names were dropped – instead trim levels became Dart, Dart 330, Dart 440, and Polara 500, offered in downsized two- and four-door hardtop, and convertible styles, that stood out by their raised, protruding grilles, encompassing what look like inner headlights, similar to the inner headlights in the protruding grille of a 1969 Ford Mustang . The Dodge Polara 500

#17328696954986396-530: The Swinger 2-door hardtop for 1969 available in Custom, GT, and GTS trim. Also added was the Swinger 340. The entire 1969 Dart range received trim updates including another minor revision of the grille and a return to rectangular park/turn lights. The 1968 round side marker lights were replaced with rectangular reflectors. Head restraints were optional equipment until January 1, 1969, when their installation became mandatory under federal law. The 6-cylinder models received
6519-523: The U.S. and Canada had a 3-speed column-mounted shifter—the first generation Chevrolet/GMC vans of 1964–70 vintage had an ultra-rare 4-speed column shifter. The column-mounted manual shifter disappeared in North America by the mid-1980s, last appearing in the 1987 Chevrolet pickup truck . Prior to 1980, the GM X platform compacts (Chevrolet Nova and its rebadged corporate clones) were the final passenger cars to have

Early automobiles used sliding-mesh manual transmissions with up to three forward gear ratios. Since
6765-519: The big Chevrolets, but of the compact Chevy II Nova . This was a basic front-engine compact to compete more directly than the Corvair with the Ford Falcon , Rambler American , and Plymouth Valiant . Chevrolet's Impala and Ford's Galaxie both remained sized in accord with the prevailing norms of full-size cars. The redesigned Dart was perceived more as an intermediate, like the Rambler Classic or
6888-578: The car was advertised as a performance car. The Demon's Dart-type front fender wheel lips and Duster-type rear wheel fender lips reveal the car was essentially a Duster with Dart front sheet metal and other minor styling changes. A new audio option became available for 1971: Chrysler's cassette-recorder. Unlike the 8-track tapes, the cassette player was relatively compact, and it was mounted on the console or on its own floor-mount casing. This unit offered an available microphone in which one could record their own dictation. The Swinger 340, Dart's performance model,
7011-482: The central divider of the 1970 and 1971 items, new surface-mounted sidemarker lights rather than the previous flush-mount units, the instrument cluster was now shared with the Valiant and featured a large, rectangular speedometer and several, small, round gauges; the AM/FM-radio option returned. The Demon had new fender-mounted metal "Demon" badges without the small devil character on the 1971 decals. The "Demon" decal on

Most manual transmissions for cars allow the driver to select any gear ratio at any time, for example shifting from second to fourth gear, or fifth to third gear. However, sequential manual transmissions , which are commonly used in motorcycles and racing cars , only allow the driver to select the next-higher or next-lower gear. In a vehicle with
7257-484: The collar from bridging the locking rings while the speeds are still being synchronized. This is achieved through 'blocker rings' (also called 'baulk rings'). The synchro ring rotates slightly because of the frictional torque from the cone clutch. In this position, the dog clutch is prevented from engaging. Once the speeds are synchronized, friction on the blocker ring is relieved and the blocker ring twists slightly, bringing into alignment certain grooves or notches that allow
7380-460: The concave grille was highly unpopular with consumers. The low position and small size of the Dart's tail lights , just above the corners of the bumper, was also criticized and drivers of following cars complained that they could not see them. The wraparound taillights projected light sideward, not rearward. By mid-year, Dodge made auxiliary taillights available at extra cost through its dealer network. However, these large round lights were mounted near
7503-463: The cone-shaped sleeve on the dog collar so that the friction forces can reduce the difference in rotational speeds. Once these speeds are equalized, the dog clutch can engage, and thus the new gear is now in use. In a modern gearbox, the action of all of these components is so smooth and fast it is hardly noticed. Many transmissions do not include synchromesh on the reverse gear (see Reverse gear section below). The synchromesh system must also prevent

#17328696954987626-421: The dashboard. Other changes to comply with new federal safety laws included collapsible steering columns, additional padding on the dashboard and sun visors. Shoulder belt anchors were also provided for front outboard occupants. The 1967 redesign removed all traces of the older Virgil Exner styling that proved less popular by the early 1960s. The newer body was trimmer and proved extremely popular, causing sales of
7749-431: The division's highest total to date, and good for sixth place behind Chevrolet, Ford, Plymouth, Rambler, and Pontiac. Chrysler officials were somewhat less comforted at how 87% of Dodge's volume consisted of the low-profit Dart line, compared to the upmarket Matador and Polara, of which only 41,000 were sold for the 1960 model year. As the Dart's sales climbed, Plymouth's sales dropped. Chrysler executives did little to stop
7872-438: The dog clutch to fall into the engagement. Common metals for synchronizer rings are brass and steel , and are produced either by forging or sheet metal shaping. The latter involves stamping the piece out of a sheet metal strip and then machining to obtain the exact shape required. The rings are sometimes coated with anti-wear linings (also called 'friction linings') made from molybdenum , iron , bronze or carbon (with
7995-427: The dog clutches require the input shaft speed to match that of the gear being selected; otherwise, the dog teeth will fail to engage and a loud grinding sound will be heard as they clatter together. Therefore, to speed up or slow down the input shaft as required, cone-shaped brass synchronizer rings are attached to each gear. When the driver moves the gearshift lever towards the next gear, these synchronizer rings press on
8118-425: The doors and new emission control devices. New single-piston disc brakes replaced the more complex 4-piston units offered from 1965 to 1972. Chrysler's new electronic ignition system was standard equipment on all engines, and starter motors were revised for faster engine cranking. The K-frame was modified to accommodate a new spool-type engine mount that limited engine roll to 3°. The upper ball joints were upgraded to
8241-413: The early 1950s, most cars only had synchromesh for the shift from third gear to second gear (drivers' manuals in vehicles suggested that if the driver needed to shift from second to first, it was best to come to a complete stop beforehand). Up until the late 1970s, most transmissions had three or four forward gear ratios, although five-speed manual transmissions were occasionally used in sports cars such as
8364-431: The end of A-body production in 1976 for North America and 1981 for South America. The restyled Dart for 1967 featured a rear window with compound inverse curves. This created a unique appearance at the rear of the greenhouse , but tended to collect snow and created thick C-pillars that looked formal but created blind spots for drivers. Curved side glass was used for the first time on a Chrysler compact. The front featured
8487-407: The energy generated by the wheels moving on the road is transferred to the driveshaft, then the transmission, and eventually the crankshaft. When the crankshaft spins as a result of the energy generated by the rolling of the vehicle, the motor is cranked over. This simulates what the starter is intended for and operates in a similar way to crank handles on very old cars from the early 20th century, with
8610-435: The engine ( clutch disengaged – the clutch pedal is being pressed down). When the engine is running and the clutch is engaged (i.e., clutch pedal up), the flywheel spins the clutch pressure plate and hence the transmission. The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. This is a fundamental difference compared with
8733-456: The engine speed within the optimal power band for all typical road speeds. Operating such transmissions often uses the same pattern of shifter movement with a single or multiple switches to engage the next sequence of gears. Many of the first automobiles were rear-engined, with a simple belt-drive functioning as a single-speed transmission. The 1891 Panhard et Levassor is considered a significant advance in automotive transmissions since it used
8856-422: The federally mandated steering column and ignition lock. The "Swinger" name was applied to all the Dart two-door hardtops except in the high-line custom series. Other changes were made to the Dart line to avoid internal competition with Dodge's new Challenger : the Dart convertible was discontinued along with the optional 383 cu in (6.3 L) V8, leaving the 275 bhp (205 kW) 340 4-barrel V8 as
8979-399: The fifth selector on the main shaft. This means that when the vehicle is stopped and idling in neutral with the clutch engaged and the input shaft spinning, the third-, fourth-, and fifth-gear pairs do not rotate. When neutral is selected, none of the gears on the output shaft are locked to the shaft, allowing the input and output shafts to rotate independently. For reverse gear, an idler gear
9102-453: The first Dodge models to bear the "Charger" name. The following year the larger B-body Dodge Charger was introduced, and the "Charger" name was thenceforth associated with Dart models only in the "Charger 225" marketing name for the optional larger 6-cylinder engine. Other new options for 1965 included upgraded suspension components and larger 14 in (356 mm) wheels and tires. Factory-installed air conditioning became available after
9225-521: The first-gen Fiat Ducato . Many European cars had manual column shifts and the Renault 16TX had a 5 speed. Column shifters are mechanically similar to floor shifters, although shifting occurs in a vertical plane instead of a horizontal one. Because the shifter is further away from the transmission, and the movements at the shifter and at the transmission are in different planes, column shifters require more complicated linkage than floor shifters. Advantages of
9348-442: The forces required or provide a faster shift time . The first car to use a manual transmission with synchromesh was the 1929 Cadillac . Most North American marques had adopted synchronized manual transmissions, usually for second and high gears, by the mid-1930s. In 1947, Porsche patented the split ring synchromesh system. The 1952 Porsche 356 was the first car to use a transmission with synchromesh on all forward gears. In
9471-401: The forward gears. These devices automatically match the speed of the input shaft with that of the gear being selected, thus removing the need for the driver to use techniques such as double-clutching . The synchromesh transmission was invented in 1919 by Earl Avery Thompson and first used on production cars by Cadillac in 1928. The need for synchromesh in a constant-mesh transmission is that
9594-418: The front-wheel-drive transaxle's ring gear. This allows for a narrower transmission since the length of each countershaft is halved compared with one that contains four gears and two shifters. The fixed and free gears can be mounted on either the input or output shaft or both. For example, a five-speed transmission might have the first-to-second selectors on the countershaft, but the third-to-fourth selector and
9717-437: The gear shift in comparison to the column shifter makes console shifters easier to operate than column shifters. In the 1950s, 1960s, and 1970s, fuel-efficient highway cruising with low engine speed was in some cases enabled on vehicles equipped with 3- or 4-speed transmissions by means of a separate overdrive unit in or behind the rear housing of the transmission. This was actuated either manually while in high gear by throwing
9840-410: The gearshift lever into reverse results in gears moving to mesh together. Another unique aspect of the reverse gear is that it consists of two gears—an idler gear on the countershaft and another gear on the output shaft—and both of these are directly fixed to the shaft (i.e. they are always rotating at the same speed as the shaft). These gears are usually spur gears with straight-cut teeth which—unlike
9963-532: The glass on the interior door panel. To keep glass up, the strap latched to the inside of the door. The interior included only two bucket seats from a Dodge van. The center console , heater, sound deadeners, side-view mirrors, radio , carpeting , and even armrests were omitted to save weight. The engine was a race-spec 426 Hemi. These motors had a compression ratio of 10.25:1 pistons , bore x stroke 4 + 1 ⁄ 4 in × 3 + 3 ⁄ 4 in (108.0 mm × 95.3 mm) fed through
10086-410: The helical teeth used for forward gear—results in a whining sound as the vehicle moves in reverse. When reverse gear is selected, the idler gear is physically moved to mesh with the corresponding gears on the input and output shafts. To avoid grinding as the gears begin to the mesh, they need to be stationary. Since the input shaft is often still spinning due to momentum (even after the car has stopped),
10209-487: The inboard side of the reverse fins and aggravated the already awkward styling. The 1961 automobile market was generally an off-year for automobile sales, and Dodge production went down to 269,367 units, of which 142,708 were Darts. Among all the Darts sold, almost half (66,100) were the Seneca line, down from 111,600 in 1960. Combined sales of Dart and Polara were lower than Plymouth's sales for 1961. Dodge ranked ninth in sales in
10332-419: The infighting between the divisions. Dart sales were so strong in 1960 that production of the medium-priced model lines were reduced. The full-size, mid-priced Matador was discontinued after the 1960 model year as buyers selected the slightly smaller but better-appointed and less expensive Dart Phoenix. The premium Polara remained in the medium-price segment in 1961. For the 1961 model year, the Dart continued as
10455-411: The larger B-body units. Along with these chassis changes, the wheel bolt pattern on Darts with disc brakes was enlarged from 4 in (101.6 mm) to the 4.5 in (114.3 mm) pattern common to the larger B- and C-body Chrysler-built passenger cars. Darts with 4-wheel drum brakes continued with the smaller bolt pattern. The standard rear axle was still the 7¼-inch unit, but the heavy-duty option
10578-645: The late 1930s and became common during the 1940s and 1950s. If a U.S. vehicle was equipped with overdrive , it was very likely to be a Borg-Warner type, operated by briefly backing off the accelerator pedal when above 28 mph (45 km/h) to enable, and momentarily flooring the same pedal to return to normal gear. The control simply disables overdrive for such situations as parking on a hill or preventing unwanted shifting into overdrive. [REDACTED] Later, European and Japanese models began to have 4-speed column shifters with this shift pattern: [REDACTED] A majority of North American-spec vehicles sold in
10701-399: The latter usually reserved for high-performance transmissions due to their high cost). Mechanical wear of the synchronizer rings and sleeves can cause the synchromesh system to become ineffective over time. These rings and sleeves have to overcome the momentum of the entire input shaft and clutch disk during each gearshift (and also the momentum and power of the engine, if the driver attempts
10824-459: The mechanical linkage for the clutch pedal is replaced by an actuator , servo , or solenoid and sensors , which operate the clutch system automatically when the driver touches or moves the gearshift . This removes the need for a physical clutch pedal. A manual transmission requires the driver to operate the gear stick and clutch in order to change gears (unlike an automatic transmission or semi-automatic transmission , where one (typically
10947-429: The model year; the 1968 GTS was, arguably, improved by fitting the new high-output 340 cu in (5.6 L) V8 as standard equipment. The 1967 Dart, along with all other 1967 Chrysler products, got a new dual-circuit brake hydraulic system to ensure a loss of pressure in the front brakes would not prevent the rear brakes from working, and vice versa. The system also incorporated a brake system fault telltale on
11070-428: The name Zipp. This was promptly rejected in favor of Dart. With the cancellation of Chrysler's upper level DeSoto brand, upper-level Dodge products were pushed upmarket, while using Plymouth products with more features for lower-level Dodge products. The Dart sedans and coupes were based on the unibody Plymouth platform with a 118 in (2,997 mm) wheelbase, shorter than the standard-size Dodge line. However,
11193-412: The nearly pure unibody platform combined with the suspension's low unsprung weight and near-ideal geometry provided sound handling, braking, and acceleration; the latter especially with the mid-year 415 hp (309 kW) "Ramcharger" 413 cu in (6.8 L) V8 which was aimed primarily at sanctioned drag racing, where it quickly broke performance records. The Dart's new B-body chassis platform
11316-462: The nickname "crash" because the difficulty in changing gears can lead to gear shifts accompanied by crashing/crunching noises. Vehicles with manual transmissions use a clutch to manage the linkage between the engine and the transmission, and decouple the transmission from the engine during gearshifts and when the vehicle is stationary. Without a clutch, the engine would stall any time the vehicle stopped, and changing gears would be difficult (deselecting
11439-413: The only compact Darts so equipped. Standard axle ratios in 1964 were 2.93:1 with automatic transmission and 225 engine, or 3.23:1 with manual transmission and 225 engine, or with 170 engine and either transmission. A 3.55:1 ratio was optional. New features included stronger door locks and a refined automatic choke. In 1965, the 2-barrel 273 remained available, but a new performance version of the 273 engine
11562-406: The other shaft, with a bearing located between the two shafts. In a transmission for transverse engined vehicles (e.g., front-wheel-drive cars), there are usually only two shafts: input and countershaft (sometimes called input and output). The input shaft runs the whole length of the gearbox, and there is no separate input pinion. These transmissions also have an integral differential unit, which
11685-485: The output shaft gears are able to rotate independently of the output shaft itself (through the use of bearings located between the gears and the shaft). Through the use of collars (operated using the shift rods ), the speed of the output shaft becomes temporarily locked to the speed of the selected gear. Some transmission designs—such as in the Volvo 850 and S70—have two countershafts, both driving an output pinion meshing with
11808-424: The output shaft. When the driver selects a gear, the dog clutch for that gear is engaged (via the gear selector rods), locking the transmission's output shaft to a particular gear set. This means the output shaft rotates at the same speed as the selected gear, thus determining the gear ratio of the transmission. The dog clutch is a sliding selector mechanism that sits around the output shaft. It has teeth to fit into
11931-477: The previous Lancer or the contemporaneous Valiant. The Dart was available as a 2- or 4-door sedan , a 2-door hardtop coupe, a station wagon , and a convertible. Three trim levels were offered: the low-spec 170 , the high-spec 270 , and the premium GT , which was available only as a 2-door hardtop or convertible. The 1963 Dart has a turning diameter of 38.9 ft (11.9 m). The Dart was an instant market success, with 1963 sales up sharply compared to those of
12054-476: The rear of the car was replaced by Dodge and Dart emblems on the lower right edge of the deck lid. Some Demons with the side and rear panel tape stripes retained the tape devil character. A new, optional, single, hood scoop replaced 1971's dual scoops, and was coupled with a hood-paint blackout that had been standard on the 1971 high-trim/high-value Demon Sizzler model. Cars equipped with the optional rally wheels now came with newly restyled center caps, finished in
12177-501: The rear, the Dart's new rectangular tail lights were set into a wedge-shaped rear bumper design continuing the angled trailing edge of the new deck lid and quarter panels. The revised rear styling did not change the 14.1 cubic ft trunk space of the 1969 model. 14-inch wheels became standard equipment, and the 170 cu in (2.8 L) slant-6 was replaced by a larger 198 cu in (3.2 L) version for improved base-model performance and greater manufacturing economy—the 198 used
12300-449: The revised camshaft the bigger engine had received in 1965. For North American domestic-market vehicles, the base 170 engine was replaced for 1970 with a stronger new 198 cu in (3.2 L) version of the slant-6. This new base engine was also less costly to make, for unlike the previous 170 engine, the 198 used the same block as the 225. The smaller displacement was achieved with a new crankshaft (3.64 in (92 mm) stroke vs.
12423-401: The same axis, since this reduces the torsional forces to which the transmission casing must withstand. The assembly consisting of both the input and output shafts is referred to as the main shaft (although sometimes this term refers to just the input shaft or output shaft). Independent rotation of the input and output shafts is made possible by one shaft being located inside the hollow bore of
12546-622: The same block as the 225, while the 170 had used a different block. Changes to the fuel system improved drivability, economy, and emission control. Part-throttle downshift was added to the 8-cylinder automatic transmissions. In compliance with FMVSS 108 , side marker lights and reflectors were installed at all four corners. 1970 Darts for the US and Canadian markets were built in Canada at the Windsor, Ontario, or Los Angeles, California assembly plant. All 1970 Darts got
12669-441: The same speed when engaged; otherwise, the teeth would refuse to mesh. This was difficult to achieve, so gear changes were often accompanied by grinding or crunching sounds, resulting in the gearboxes being nicknamed "crash boxes". Even after passenger cars had switched to synchronous transmissions (i.e. with synchronizers), many transmissions for heavy trucks, motorcycles and racing cars remained non-synchronous, in order to withstand
12792-422: The selector forks within the transmission. Motorcycles typically employ sequential manual transmissions , although the shift pattern is modified slightly for safety reasons. Gear selection is usually via the left-foot (or, on older motorcycles; right-foot) shift lever with a layout of 1–N–2–3–4–5–6. During the period when U.S. vehicles usually had only three forward speeds, the most common gear-shifter location
12915-498: The smallest full-size Dodge. It retained the 118 in (2,997 mm) wheelbase, and was restyled to emulate the larger Polara. The same three trim levels were available: the premium Phoenix, mid-range Pioneer, and base Seneca. Once again, wagons shared the Polara's 122 in (3,099 mm) wheelbase; they also shared the Polara's unique side-mounted taillights. Engine choices included the 225 cu in (3.7 L) slant-six, and
13038-416: The standard bench seat with all-vinyl bucket seats, with which a center console could be ordered. A performance hood upgrade with scoops was painted flat black with hood tie-down pins. Mechanical options included power-assisted brakes and steering. Rallye wheels and wire wheel covers were also optional, as was a 6000 rpm tachometer and a vinyl roof covering in black or white. For 1971, Chrysler introduced
13161-452: The start of the 1965 model year, as well as disc brakes , which required the 14 in (356 mm) wheels to clear the calipers. Front seat belts became standard. The 170 cu in (2.8 L) Slant-6 engine remained standard equipment, though its power rating rose from 101 bhp (75 kW) to 115 bhp (86 kW) for 1967, owing to the installation of the 225 engine's 1 barrel Carter BBD or Holley 1904 series carburetor and
13284-494: The top Dart engine. The performance model in the Dart line for 1970 was the Swinger 340 2-door hardtop. The 1970 Swinger 340 came with functional hood scoops with 340 emblems. Standard equipment included front disc brakes (only on the Swinger), heavy-duty "Rallye" suspension, a 3.23:1 rear axle ratio, fiberglass-belted bias-ply tires mounted to 14 × 5½ inch steel wheels, and a bumblebee stripe. Optional equipment included an upgrade over
13407-479: The transmission. FF (front-engined, front-wheel drive) vehicles, RR (rear-engined, rear-wheel drive) vehicles and front-engined vehicles with rear-mounted gearboxes often require a mechanical linkage to connect the shifter to the transmission. Some vehicles have a gear lever mounted on the steering column. A 3-speed column shifter, which came to be popularly known as a "three on the tree", began appearing in America in
13530-467: The vehicle's transmission in much the same way a floor-mounted shifter can. However, because of the location of the gear shifter in comparison to the locations of the column shifter and the floor shifter, as well as the positioning of the shifter to the rest of the controls on the panel often require that the gearshift be mounted in a space that does not feature a lot of controls integral to the vehicle's operation, or frequently used controls, such as those for
13653-674: Was added as a refinement to the TorqueFlite automatic transmission in 6-cylinder cars, to retain acceptable city performance with the taller rear axle ratio. A limited option for 1968 only, code L023, the Hurst-reworked Hemi Darts used the 426 cu in (7.0 L) Hemi engine. These special models (only 80 were made) were created strictly for drag racing , and included a non-warranty disclaimer. On February 20, 1968, corporate headquarters in Highland Park, Michigan , sent out
13776-423: Was added in 1961. Brakes were 11-inch drums. Sales of the new Dart were greater than those of the full-size Dodge Matador and Dodge Polara , which also created an in-house competitor for Plymouth. Advertising from 1960 and 1961 compared the Dart to the "C" car ( Chevrolet ), the "F" car ( Ford ) and the "P" car (Plymouth). After the economic downturn of 1958–59, Dodge production for 1960 rebounded to 367,804 cars,
13899-522: Was available at extra cost. The alternator , introduced as standard equipment in 1960 on the Valiant , replaced the previous DC generator on all 1961 Chrysler products. Canadian-built 1961 Darts were identical to U.S. models on the outside, but the interior trim, controls, and displays were those used on the U.S. Plymouth. Virgil Exner 's 1961 styling with its reverse fins, rear fender scalloping (the taillights were widely referred to as "ingrown toenails"), and
14022-471: Was available for less than $ 50 extra. The aluminum engine block for the 225 was discontinued early in the 1963 model year. After the start of the 1964 model year, an all-new, compact, lightweight 273 cu in (4.5 L) LA V8 producing 180 bhp (130 kW) with a 2-barrel carburetor was introduced as the top engine option. 1964 was the last year for pushbutton control of the optional Torqueflite automatic transmission, so 1963 and 1964 models were
14145-433: Was dimensionally identical but not officially a Dart by dint of its different name, and it was not built nor sold in Canada. The Dart models were the same in Canada as in the U.S. except that the base model was badged Dart 220 . The Dart and Polara were downsized as part of Chrysler's hasty effort to compete with what company leaders thought would be downsized large cars from Chevrolet. However, they had overheard talk not of
14268-459: Was introduced in the 2012 Porsche 911 (991) . In 2008, 75.2% of vehicles produced in Western Europe were equipped with manual transmission, versus 16.1% with automatic and 8.7% with other. A manual transmission has several shafts with various gears and other components attached to them. Most modern passenger cars use 'constant-mesh' transmissions consisting of three shafts: an input shaft ,
14391-417: Was now an 8¼-inch item rather than the previous 8¾-inch rear axle. Standard rear axle ratios were 2.76:1 with automatic transmission and 3.23:1 with manual, though other ratios were available. Vent wings were deleted from the Swinger but not from the 4-door sedans. A new "Quiet Car" package was available, consisting of extra sound insulation, premium exhaust hangers, and an exhaust resonator. The Demon fastback
14514-461: Was on the steering column, a layout that was sometimes called "three on the tree". By contrast, high-performance cars, and European vehicles in general, mostly used a four-speed transmission with floor-mounted shifters. That layout was referred to as "four on the floor". Most FR (front-engined, rear-wheel drive) vehicles have a transmission that sits between the driver and the front passenger seat. Floor-mounted shifters are often connected directly to
14637-485: Was optional. The Dart and its sister model—the Plymouth Valiant—were substantially redesigned for the 1967 model year. In addition to new styling, the cars received revised steering systems, wider front track and frame rail spacing, and redesigned K-members capable of accepting larger engines. The Dart kept this basic form, with facelifts consisting of revised front and rear-end styling and interior trim, until
14760-495: Was quite long-lived; while 1962 was the only year for a B-body model named "Dart", the B platform remained in use with only very slight modification and a few new letter designations through to the 1981 R-body cars. For 1963, Dodge made a last-minute decision to drop the Lancer name in favor of Dart for Dodge's newly designed "senior compact", a marketing term referring to the wheelbase having grown to 111 in (2,819 mm) from
14883-517: Was released with a 4-barrel carburetor, 10.5:1 compression, a more aggressive camshaft with solid tappets, and other upgrades which increased output to 235 bhp (175 kW). At the same time, the Dodge Dart Charger was offered. The Dart Chargers were yellow Dart GT hardtops with black interiors, Charger 273 engines, (Plymouth called their 4 barrel 273 Commando), premium mechanical and trim specifications, and special "Charger" badging. They were
15006-418: Was renamed "Dart Sport" in response to poor sales. It was thought that the "Demon" name and devil-with-pitchfork logo negatively affected sales to people of faith. The high-performance model thus became Dart Sport 340, and 1973 saw styling changes to go along with the name change. The Dart Sport received the same new front end as the other Darts, and its taillights were changed to two lights per side, each with
15129-412: Was replaced by the Demon 340, 275 HP engine with an optional 4-speed manual transmission, optional hood scoops, and blackout hood treatment. In 1971, Chrysler ended their longstanding corporate practice of installing left-hand-threaded wheel studs on the left side of the vehicle; all-wheel studs on the Dart thenceforth used conventional right-hand threads. Changes for 1972 included a revised grille without
