Abstract
The invention provides a transmission case that includes a rear housing that partially encloses transmission components about a center axis. The rear housing sealingly connects to a main housing at one end and to a drive unit extension at another end. The rear housing has an axial passage generally parallel to the center axis and a cross passage that is substantially perpendicular to the axial passage. The cross passage is in fluid communication with the axial passage to allow draining of fluid within the drive unit extension to the main housing. A method of returning fluid to a transmission oil sump is also provided.
