Abstract
A lubrication mechanism is provided for a transmission unit having a balance piston. The lubrication mechanism is movable between a closed position when a clutch assembly is disengaged which prevents cooling flow of lubrication to a clutch pack of the clutch assembly, and an open position when the clutch assembly is engaged which provides for a cooling flow of lubrication to the clutch pack. In both positions, lubrication is supplied to a balance piston cavity between the clutch assembly and the balance piston.
