ABSTRACT:
A damper device for a torque converter clutch to allow slipping of the clutch under low torque transmitting conditions to absorb objectionable torque fluctuations. A fluid communication port in the clutch plate is exposed or covered to control the pressure differential across the clutch plate which operates the clutch. A valve member is connected to the turbine vane wheel on the output side of the torque converter to expose or cover the hole as the torque being transmitted is reduced or increased, respectively. In one form the valve member is mounted on the turbine vane wheel while in another form it is mounted on the clutch plate.
