ABSTRACT:
A positive displacement hydraulic mechanism for controlling the engagement of a slipping clutch in parallel drive relationship with a torque converter. The hydraulic device is operable in response to the speed differential between the impeller (input) and turbine (output) of the torque converter to control fluid flow from one side of a single plate clutch thereby controlling the pressure differential across the plate of the clutch so that the engagement force of the clutch is controlled to maintain a fixed speed differential between the turbine and impeller.
