ABSTRACT:
A device for controlling the supply pressure of a hydraulic actuator for an automatic transmission of an automobile. A pressure modulator varies the hydraulic pressure depending on the output of a controller. The controller receives input information on engine speed, turbine speed, engine load and vehicle speed. The transmission is controlled to be disengaged when the automobile is stopped, and reengaged smoothly.
