Although not strictly a part of classic torque converter design, many automotive converters include a lock-up clutch to improve cruising power transmission efficiency and reduce heat. The application of the clutch locks the turbine to the impeller, causing all power transmission to be mechanical, thus eliminating losses associated with fluid drive.
For the 1981 model year, a lock-up torque converter was introduced which coincided with the new EMC control of most GM cars; this version is the THM350-C, which was phased out in 1984 in GM passenger cars for the 700R4. Chevrolet/GMC trucks and vans used the THM350-C until 1986. The lock-up torque converter was unpopular with transmission builders.
Many TCUs now have an input from the vehicle's traction control system. If the TCS detects unfavourable road conditions, a signal is sent to the TCU. The TCU can modify shift programmes by upshifting early, eliminating the torque converter lock-up clutch application, and also eliminating the first gear totally and pulling off in 2nd. [3]
Toyota Motor Corporation's A family is a family of automatic FWD/RWD/4WD/AWD transmissions built by Aisin-Warner.They share much in common with Volvo's AW7* and Aisin-Warner's 03-71* transmissions, which are found in Suzukis, Mitsubishis, and other Asian vehicles.
The early model C4 (1964–1969) used a .788-inch 24-spline input shaft, which was upgraded in 1970 to 26-spline and .839-inch. The upgrade also included a matching 26-spline clutch hub. In 1971, Ford went to a 26/24-spline input shaft, meaning the torque-converter side is 26-spline and the clutch hub is 24-spline.
During the 1980s, automatic transmissions with four gear ratios became increasingly common, [31] and many were equipped with lock-up torque convertors in order to improve fuel economy. Electronics began to be more commonly used to control the transmission, replacing mechanical control methods such as spring-loaded valves in the valve body.
The aluminum die-cast case is 10 % lighter, yet 30 % more rigid, even with two additional gears and a 22 % greater torque capacity the new transmission weighs 95 kg (209 lb) or 10 % more than the previous unit. With new micro-laser technology gear tooth production tolerances have been reduced 50 %.
Other than the bell housing pattern (main transmission case) and the torque converter, the AMC version is the same as other Chrysler transmissions—all parts interchange (torque converters do not interchange - unlike the Chrysler torque converters which have a pressed on ring gear for the starter teeth AMC uses a traditional 164 tooth ...
