Abstract
A clutch includes a clutch fluid chamber with a movable clutch piston configured to selectively engage a clutch pack to connect an input drive portion and an output portion. A brake reaction plate is configured for selective frictional braking of the output portion. A brake fluid chamber contains a brake piston configured to selectively move the brake reaction plate from a disabled position to an enabled position. In a first state, the clutch pack is disengaged and the brake reaction plate is in the disabled position. In a second state, the clutch pack is engaged and the brake reaction plate is in the enabled position, without frictional braking of the output portion of the clutch being applied. In a third state, the clutch pack is disengaged and the brake reaction plate is in the enabled position such that frictional braking of the output portion is applied.
