TorqueFlite (also spelled Torqueflite) was the trademarked name of Chrysler Corporation's three-speed automatic transmission, which was introduced late in the 1956 model year. TorqueFlite was introduced on the heels of the company's two-speed PowerFlite automatic, which made its debut in 1954. In the 1990s the TorqueFlite name was dropped and the transmissions were referred to by a model number referring to their torque rating and gear set, although some models remained completely unchanged.

History The first Torqueflites provided three speeds forward plus reverse. Gear ratios were 2.45:1 in first, 1.45 in second, and 1.00 in third. The transmission was controlled by a series of pushbuttons located on the vehicle's dashboard to the left of the steering column. Button arrangement varied by vehicle model and year; sequence was Reverse, Neutral, Drive, Second, and First, from top to bottom with vertically-arrayed buttons, from left to right with horizontally-arrayed buttons, and clockwise starting at upper left with clustered buttons. A parking lock was not provided until the advent of the aluminum-case Torqueflite in 1960 (standard-duty A-904) 1962 (heavy-duty A-727), at which point a lever was added adjacent to the pushbuttons: Throwing the lever to the "Park" position placed the car into Neutral and engaged a lock pawl on the transmission's output shaft. Throwing the park lever out of "Park" position unlocked the shift buttons so that a driving range could be selected. The buttons were replaced by conventional steering column- or floor-mounted shift levers in all automatic Chrysler-built vehicles for the 1965 model year.
Unlike some competing automatic transmissions of its era, Torqueflite started in first gear when placed in Drive; Ford Motor Company's Ford-O-Matic and Borg-Warner's automatics started in second unless started in Low. Selecting 2 or 1 locked out third and second gear, respectively, which allowed the driver to manually control shift points. Second-gear starts were not available by any means. It has been suggested that this article be split into articles entitled Ford Motor Company and Ford (vehicles). ...

1962 brought the addition of a canister-style fluid filter factory-installed in the cooler line. For 1964, the canister filter was eliminated, and the transmission's internal intake screen was replaced by an efficient Dacron filter. Fluid life starting in 1964 was extended from 12,000 to 50,000 miles, providing justification for the deletion of the drain plug from the oil pan. The term plastics covers a range of synthetic or semi-synthetic organic condensation or polymerization products that can be molded or extruded into objects or films or fibers. ...
For 1966, the twin-cable shift and park control mechanism was replaced by a simple, single-action solid shift control linkage consisting of a series of pushrods, rotating rods and levers. The rear pump was eliminated, which simplified and cost-reduced the transmission but rendered push-starting impossible; Chrysler engineers reasoned that improved electrical and fuel systems reduced the need to push-start vehicles, and safety concerns weighed against doing so. The gated shift quadrants also permitted the deletion of the reverse safety blocker valve which, in TorqueFlites made through 1965, had shifted the transmission harmlessly into Neutral if the Reverse position were selected with the vehicle moving forward above approximately 3 mph.
In 1968, part-throttle downshift functionality was added to A-904 transmissions used with 6-cylinder engines. This feature permitted the transmission to shift from third to second gear in response to moderate accelerator pressure. Previously, an automatic 3-2 downshift occurred only if the driver pushed the accelerator to the floor. This change was made to maintain acceptable in-town performance with the newly-adopted taller final-drive ratios in the rear axle (2.76:1 rear axle gears were furnished in applications previously equipped with 2.93:1 or 3.23:1 gearsets). Part-throttle downshift functionality was extended to V8 A-904s in 1969, and to most A-727 transmissions in 1970 to 1971.
In 1978, most TorqueFlite transmissions gained a lock-up torque converter (a clutch to mechanically connect the impeller and turbine of the torque converter, eliminating slippage) in the interests of improved fuel economy. This addition required the removal of the torque converter drain plug. Fuel efficiency, sometimes also referred to as fuel economy and commonly gas mileage in the United States, is a numeric measure often used to describe the amount of fuel consumed with regard to the distance travelled in a transportation vehicle, such as an automobile. ...
For 1980, a wide-ratio gearset was released for the A904, A998 and A999, with 2.74:1 in first, 1.54 in second, and 1.00 in third.
TorqueFlite was an available option or standard equipment, depending on model and year, on all Chrysler products (Plymouth, Dodge, DeSoto, Chrysler and Imperial) and on various American Motors (AMC), Jeep, International Harvester, Maserati Quattroporte, Monteverdi [1] and Bristol [2] brand vehicles as well. AMC referred to the transmission as the Torque-Command. When installed in Dodge trucks and vans, the transmission was marketed as LoadFlite.

In the 1990s the transmissions were renamed, however the TorqueFlite remains the basis of all current Chrysler designed transmissions. Jeep used several other manufacturers transmissions until 1997, and Mercedes-Benz uses its own design identified by the number "722". Also several of the pickup lines now use transmissions from various sources.

A488 The original TorqueFlite was designated A488, with a cast iron case and no parking pawl. Cast iron usually refers to grey cast iron, but can mean any of a group of iron-based alloys containing more than 2% carbon (alloys with less carbon are carbon steel by definition). ...
A727 The A488 was replaced in 1962 with the A727 (later 36RH, 37RH), with an aluminum case to reduce weight by about 60 lb (27 kg). The A727 incorporated a parking pawl and various internal improvements. The 727 used either a 10.75 in or an 11.75 in (273 or 298 mm) torque converter. The heavier-duty A727 TorqueFlites became popular (and remain popular to this day) for drag racing and monster truck applications because of their controllability and strength. Aluminum is a soft and lightweight metal with a dull silvery appearance, due to a thin layer of oxidation that forms quickly when it is exposed to air. ...

A904 For standard-duty applications in smaller and lighter vehicles with Slant-6 or small V8 engines, with relatively modest torque and a compact case, the A904 (later 30RH) was introduced in 1960. This transmission used a 10.75 in (273 mm) torque converter. Slant 6 was an all-female punk rock trio based in Washington, D.C.

In the late 1970s, Chrysler designed the A404 TorqueFlite 3-speed automatic transaxle for its front wheel drive Dodge Omni and Plymouth Horizon subcompact cars. This transaxle would be upgraded in the 1980s into the A413 and A670 units, which were progressively heavier-duty, for Chrysler's K-cars and their derivatives, including the minivans. The 4-speed Ultradrive electronic 4-speed automatic transaxle would eventually replace it, but the 3-speed lasted for more than a decade after the 1989 debut of the 4-speed unit.
