The torque transfer mechanism includes a power-operated clutch actuator for generating and applying a clutch engagement force on the clutch assembly. Clutch actuator assembly includes a clutch apply operator for controlling the magnitude of a clutch engagement force applied to the clutch assembly. The clutch operator includes a first and second cam plate that are spaced form in one another to define a cavity therebetween. A sealing element extends between the first and second cam plates to seal the cavity between the first and second cam plates for retaining fluids in the cavity.
