Abstract
A method and apparatus reduces hot spotting in transmission clutch packs actuated by a piston with axial fingers engaging the clutch pack. The method and apparatus combine an alternative pack arrangement with the fingered actuator, the alternative pack preferably being an inverted double sided pack or a single sided pack. The friction plates may have single or double side friction layers, but a second set of plates are splined for rotation with the shaft when the friction plates and the piston are splined for rotation with the housing in which the shaft rotates.
