Abstract
A power transmission includes a rotary input member adapted to receive drive torque from a source of torque, a rotary output member and a torque transmitting mechanism selectively operable to transfer drive torque between the input member and the output member. The torque transmitting member includes a selectively operable one-way clutch including a rotatable member for switching the one-way clutch between a released mode and a locked mode. The torque transmitting mechanism also includes a friction clutch and an actuator. The friction clutch is operable to transmit torque to the rotatable member and control the mode of operation of the one-way clutch. The actuator is operable to apply a clutch and brake engagement force to the friction clutch.
