Abstract
A clutch assembly for a vehicle transmission includes a housing defined by a wall having an annular configuration circumscribing a clutch axis. The wall extends between an open end and a floor. The floor extends inwardly from the wall toward the clutch axis. A plurality of splines formed in the wall and each is spaced from the open end of the housing. A snap ring retains clutch plates in the housing. The open end of the wall is deformed inwardly toward the clutch axis defining a retainer for retaining the snap ring within the housing.

A method of forming housing for use with a clutch assembly, comprises the steps of:
- forming an annular wall and a floor from a continuous sheet of metal, with said annular wall terminating at a flange disposed at an opposite end of said annular wall from said floor;
- forming a plurality of splines radially inwardly of said annular wall and said splines extending between said floor and said flange;
- and
- slotting said flange for defining a plurality of teeth in a distal end of said flange, then folding said flange radially inwardly forming a retainer defining a space between said retainer and said splines, with said teeth being circumferentially aligned with said splines formed in said annular wall securing a snap ring of the clutch assembly between said retainer and said splines.
