摘要： A control system for an automatic transmission for an automative vehicle having a torque converter and a combustion engine including a microprocessor that is adapted to establish optimum control pressure levels for fluid pressure operated clutch and brake servos that effect gear ratio changes wherein provision is made for adjusting system pressures to maintain ratio shift quality in accordance with variations in a plurality of control sensor inputs including vehicle deceleration during ratio shifting and changes in the rate of change of converter turbine speed wherein optimum servo pressures are maintained following a ratio shift and during a ratio shift as torque capacity of one servo is reduced in synchronism with a torque capacity increase for a companion servo.

摘要： Controlling the speed of an engine used with an automatic transmission to reduce tip in jerk includes determining any difference between transmission gearset speed and engine speed. Engine speed is increased if it is below transmission gearset speed so as to reduce any speed differential between the engine and transmission gearset.
