Abstract
A hydraulic transmission pump assembly adapted to provide fluid under pressure to predetermined components in a transmission including a one-way clutch assembly operatively coupled to the pump and an electric motor operatively coupled to the one-way clutch. The one-way clutch is operatively connected to an engine to provide motive power the pump and the electric motor at engine speeds above a predetermined level thereby providing fluid under pressure to the transmission and driving the electric motor to generate electricity. The electric motor is operable to drive the pump at engine speeds below the predetermined level to provide fluid under pressure to the transmission during this operating condition.
