A hybrid transmission includes a multi-speed planetary gearbox, an automated shift system, and an electric motor/generator. The electric motor is operably controlled to drive the gearbox to establish an electric drive mode. The electric mode is further operable to provide a speed synchronization function during sequential gear shifting. The transmission includes plurality of power-operated clutches arranged to selectively engage components of the planetary geartbox to establish the distinct gear ratios. A central system functions to control automated operation of the power-operated clutches as well coordinated actuation of the engine and the electric motor.
