Abstract
A piston apply ring for providing a more uniform load distribution from an apply piston to clutch plates in a clutch apply piston assembly, effectively increasing the lifetime of various components of the clutch apply piston assembly, is disclosed. An L-shaped cross-sectional shape of the piston apply ring helps locate the apply ring on the clutch apply piston and prevents torsional movement between the apply ring and the apply piston. Various alternative embodiments are disclosed.
