Abstract
A clutch assembly has two pistons each having an apply chamber for independently controlling engagement of respective friction plates. An axially fixed wall is disposed adjacent the pistons opposite to the apply chambers. Fluid is admitted between the wall and the pistons such that during rotation of the clutch assembly, centrifugal pressure generated in the fluid in the apply chambers is counteracted by centrifugal pressure generated in the fluid between the wall and the pistons.
