ABSTRACT:
A clutch piston amplifier assembly is provided for applying pressure to a clutch pack for engaging a first member and second member of an automatic transmission. The clutch piston amplifier assembly utilizes an amplifier piston which applies a secondary force to an apply piston for increasing the amount of apply force that can be obtained from the clutch assembly without increasing the diameter of the apply piston or the line pressure supplied to the piston assembly.
