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.
