An electric motor has a shaft projecting from an end bearing bracket, and an annular hub member is clamped to the projecting portion of the motor shaft. The hub member supports a plurality of clutch discs and defines an impeller inlet for receiving a liquid coolant or oil which is pumped by the hub member through ports outwardly between the discs. A housing includes a section which mounts on the motor bearing bracket, and the housing has an intermediate section which supports a plurality of non-rotating brake plates. The brake plates interfit between the brake discs and are pressed together with the discs in response to axial movement of a non-rotating annular piston surrounding the hub member and supported by the intermediate section of the housing. The housing also has an end closure portion which directs the oil from the discs and plates to the inlet within the hub member and is effective to dissipate heat from the recirculating oil.
