Abstract
An electric motor damping module includes an electric motor, a motor damper continuously interconnected with the electric motor, and an input member continuously interconnected with the motor damper. A transmission includes these elements, plus an output member, first, second, and third planetary gear sets each having first, second and third members, a first interconnecting member continuously interconnecting the third member of the first planetary gear set with the second member of the second planetary gear set, a second interconnecting member continuously interconnecting the second member of the first planetary gear set and the output member with the third member of the third planetary gear set, and a third interconnecting member continuously interconnecting the third member of the second planetary gear set with the second member of the third planetary gear set. The transmission also includes six torque transmitting mechanisms and a hydraulic pump. A sealing assembly is also provided.
