Abstract
A clutch vibration damper for a clutch disposed within an automatic transmission torque converter, wherein the damping between the clutch hub and the clutch pressure plate is provided by frictional drag resulting from the clutch damper being applied simultaneous with clutch engagement. The damper is rotatively locked to the clutch hub through engaging lugs. The clutch damper is frictionally engaged to the pressure plate by the apply fluid pressure which forces the pressure plate to engage the torque converter input shell.
