ABSTRACT:
A shift control system for an automatic power transmission employs an electrically operable timing control valve. The timing control valve is disposed in a second pressure line connected to a second frictional element, which second pressure line is connected to a first pressure line connected to a first frictional element. The timing control valve is designed to be switched between a first position for shutting-off the fluid communication between the first pressure line to the second frictional element and a second position for establishing fluid communication therebetween. The timing control valve is operated by a control signal from an electric or electronic control unit which provides the control signal for the timing control valve for operating the latter with a given lag time from starting of variation of pressure in the first frictional element.
