ABSTRACT:
A control system according to the present invention is to control an automatic transmission which includes a one-way clutch and a friction element, and is shiftable from one speed ratio to another speed ratio by increasing actuating hydraulic pressure applied to the friction element and releasing the one-way clutch. In the control system, the instant when the one-way clutch is released during a shift operation when the transmission shifts from the one speed ratio to the another speed ratio is determined; and actuating hydraulic pressure applied to the friction element is regulated such that the actuating hydraulic pressure applied to the friction element is held at a fixed magnitude after said instant has been determined. The fixed magnitude is not less than the magnitude of actuating hydraulic pressure applied to the friction element when said instant is determined.
