Patent ID: 8029404

Claim:
A transmission comprising: an input member; an output member; a stationary member; first and second planetary gearsets having a plurality of planetary gearset members; a first one-way clutch operatively connected to the input member and at least one of the planetary gearset members; a second one-way clutch operatively connected to at least one of the planetary gearset members and the stationary member; a first torque transmitting mechanism being selectively engageable to couple at least one of the planetary gearset members to the stationary member; and a second torque transmitting mechanism being selectively engageable to operatively connect the input member to at least one of the planetary gearset members for unitary rotation; a motor/generator having a rotor that is operatively connected to at least one of the planetary gearset members for unitary rotation; wherein the second one-way clutch and the first and second torque transmitting mechanisms are operative in various combinations to provide four forward speed ratios between the input member and the output member.
