Abstract
A transmission includes a housing, and a transmission input member. A torque converter includes a pump and a turbine. The turbine of the torque converter is connected to the transmission input member. A lock-up clutch selectively connects the pump and the turbine. A cover is connected to and rotatable with the pump. The cover at least partially defines an interior of the torque converter. A torque converter input member passes through the cover. A one way clutch interconnects the torque converter input member and the cover. An engine brake friction clutch is disposed within the interior of the torque converter. The engine brake friction clutch selectively interconnects the torque converter input member and the cover in torque communication to transfer a braking torque therebetween.
