摘要： An automatic transmission mechanism having multiple ratio gearing and clutch and brake elements operated by fluid pressure operated servos for changing speed ratio in the transmission and a controller for actuating and releasing the clutches and brakes in response to operating demands determined by sensed variables such as vehicle speed, engine torque, manual valve position, transmission turbine speed, and engine temperature, and means for achieving improved control of a synchronous downshift event by electronically regulating the exhaust pressure from an off-going friction element of the clutch and brake structure, thus controlling the torque-carrying capacity of that off-going element during the downshift interval.

摘要： An automatic control system for a multiple ratio power transmission mechanism having a hydrokinetic torque converter (12) and multiple ratio gearing (32), the speed ratio of which is controlled by selectively engageable clutches (Cl 1 , Cl 2 , und C1 3 ) and brakes (B,) the control system including a timing valve circuit (302, 322) that is effective to establish optimum timing between the clutch (Cl 1 ,) and brake (B 1 ) engagement and release pattern during ratio changes at various driving torques and at various magnitudes of transmission throttle valve pressures, the latter being an indicator of the operator's demand for driving torque.

摘要： An automatic transmission mechanism having multiple ratio gearing and clutch and brake elements operated by fluid pressure operated servos for changing speed ratio in the transmission and a controller for actuating and releasing the clutches and brakes in response to operating demands determined by sensed variables such as vehicle speed, engine torque, manual valve position, transmission turbine speed, and engine temperature, and means for achieving improved control of a synchronous downshift event by electronically regulating the exhaust pressure from an off-going friction element of the clutch and brake structure, thus controlling the torque-carrying capacity of that off-going element during the downshift interval.
