Abstract
A balanced clutch system is provided for use in a transmission. The balanced clutch system includes a clutch assembly that has a clutch piston and a balance piston that cooperate with a clutch piston cavity and a balance piston cavity. Each of the clutch piston cavity and balance piston cavity receives a continuous supply of fluid and establishes a centrifugal head pressure therein, during use. The centrifugal head pressure established in the balance piston cavity contributes to a force that opposes a self-engaging tendency of the clutch assembly that is created by the centrifugal head pressure established within the clutch piston cavity.
