ABSTRACT:
A hybrid transmission includes an input member, an output member, a stationary member, and first and second planetary gearsets having a plurality of planetary gearset members. A first one-way clutch is operatively connected to the input member and at least one of the planetary gearset members. A second one-way clutch is operatively connected to at least one of the planetary gearset members and the stationary member. A first torque transmitting mechanism is selectively engageable to couple at least one of the planetary gearset members to the stationary member. 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.
