ABSTRACT:
A torque converter clutch has a normally closed valve member disposed on the clutch pressure plate. During normal forward (engine to transmission) torque transmission, the valve remains closed. Upon torque reversal (transmission to engine), the vibration damper associated with the clutch engages and opens the valve member so that a reduction in clutch apply pressure occurs resulting in clutch disengagement.
