Abstract: A power drive unit for a vehicle includes a monolithic housing defining a cavity that is configured to house components. The monolithic housing includes a body, a plurality of protrusions, and at least one rib. The plurality of protrusions are spaced apart from each other and protrude away from the cavity of the body. The rib protrudes from the body and extends between two protrusions of the plurality of protrusions.

Abstract: A transmission includes a torque converter, an output shaft, rotatable gearing components, a case, and a pan secured to the case. The case defines a torque converter housing for receiving the torque converter, an output shaft housing for receiving the output shaft, and a central barrel extending between the torque converter housing and the output shaft housing for receiving the rotatable gearing components. The case further defines a first hole and a second hole through a bottom wall of the central barrel and a tapering channel extending longitudinally along the central barrel from the first hole to the second hole. The pan defines a fluid reservoir disposed below the first and second holes to receive gravity-fed fluid from the tapering channel through the first and second holes.
