US 10,208,850 B1 · Transmission case with integrated drain channel

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.
