ABSTRACT:
An automatic automotive transmission is designed for drag racing. It includes a torque converter and the conventional gear sets, clutches and bands for establishing power transmission paths with different gear ratios through the transmission. The selector valve is modified to provide an additional transmission braking position adjacent the low-speed manual position. In the braking position, two different gear trains are established through the transmission, locking the transmission. This allows the torque converter to be loaded by accelerating the engine without movement of the vehicle. Release of the gear shift lever allows the selector valve to return to the low-speed manual position resulting in high acceleration of the vehicle.
