ABSTRACT:
An automatic transmission having a hydraulic torque converter and a multiple-ratio gear system in an automotive vehicle driveline wherein the converter includes a pressure-actuated bypass clutch and a control valve system for maintaining a regulated charge pressure in the torque converter and for controlling the actuation and release of the bypass clutch, the valve system including a main regulator that establishes a circuit pressure and that establishes priority distribution of pressurized fluid to the torque converter while temporarily interrupting distribution of pressurized fluid to the transmission lubrication circuit.
