Method of forming a vehicle transmission clutch housing

摘要

A clutch housing (10) for a vehicle transmission assembly and a method of making the same. The housing is generally cup-shaped with an axial hub (14). The outer wall (16) of the housing (10) is formed with a plurality of longitudinal splines (22) of varying configurations. Select splines are formed at an increased depth. A groove is formed in the exterior surface of the housing at a depth sufficient to intersect the select splines (22) of the inner surface thereby forming apertures (26) through the wall of the housing. The dimensions of the apertures (26) are determined by the configuration of the exterior groove and the interior splines (22).
