Abstract

A transmission clutch assembly includes at least one rotatable clutch plate or friction plate, a reaction plate, a non-rotatable piston, at least one bearing roller, and a cage. The reaction plate is arranged to rotate with and apply a force to the at least one rotatable clutch plate or friction plate. The non-rotatable piston is arranged for sealing engagement with a transmission housing. The at least one bearing roller arranged between and contactable with the reaction plate and the piston to permit relative rotational motion therebetween. The cage is for positioning the at least one roller and is retained by the reaction plate or the piston.
