Beschreibung
Zusammenfassung:	A hybrid transmission for use with a vehicle having an engine has an electric-only mode where the engine is off and a hybrid mode where the engine is on. The hybrid transmission includes an engine connection member configured for connection with the engine, a motor/generator unit configured to selectively operate as a motor, a transmission gearing arrangement, and a transmission input member connected with the transmission gearing arrangement. A torque transfer device is controllable to transfer torque from the motor to the transmission input member upstream in power flow from the transmission gearing arrangement, and a starter gear set includes a planetary gear set positioned in power flow between the engine connection member and the motor. The starter gear set is selectively engageable with the transmission input member and the engine connection member.
