Abstract

A clutch separator plate (24) utilized in a clutch or brake pack (10) for an automotive transmission for vehicles, with the plates being internally or externally splined to be operatively connected to the rotatable and/or stationary members (12, 14) in a torsional coupling, wherein the separator plate surfaces (44) are treated by a suitable surface treatment, such as lapping, and the sputter coated with titanium nitride or a similar material (46) to provide a surface texture which enhances the frictional characteristics of the plate but does not substantially increase the wear of the lining of interleaved clutch plates (16).
