ABSTRACT:
Methods and systems for improving the operation of a transmission for an automotive vehicle are provided for modifiying the original hydraulic circuits to increase the capacity or holding ability of the low and reverse clutches when the transmission is shifted into manual low gear to slow down a moving vehicle, to provide a quick and smooth apply of the low and reverse clutches when the driver selects manual low when the vehicle is moving at a relatively high road speed, and to permit the connection of two low hydraulic circuits to feed torque converter and cooler/lubrication circuits by application of relatively low fluid pressure to assure that the necessary pressure required to connect the circuits will be properly applied.
