ABSTRACT:
A transmission includes a housing, an electric motor having a stator within the housing, and a member including a generally cylindrical portion that circumscribes at least part of the stator. The member cooperates with the housing to form an annular coolant flowpath therebetween, and the member includes a plurality of holes to provide radial inflow of coolant from the flowpath to the stator to provide significantly improved motor cooling compared to the prior art.
