ABSTRACT:
A torque converter and slipping clutch assembly wherein the clutch engagement force is determined by the torque transmitted by the turbine of the torque converter. The clutch engagement force is controlled by differential pressure on opposite sides of the clutch plate. The pressure on one side of the clutch plate is determined by fluid flow through a variable restriction and a fixed restriction arranged in series. The size of the variable restriction opening changes in response to the torque transmitted by the turbine.
