A lubrication and shift system for a power transfer device includes an input shaft, an output shaft driven by the input shaft and a lubrication pumping system, including a pump being driven by the input shaft to provide pressurized fluid to a first fluid path. A first pump control system includes a cover plate being moveable to vary the output of the pump. A second pump control system includes a valve member selectively moveable to open and close a second fluid path. The pump output pressure is reduced when the second fluid path is open. A third pump control system includes a torque-limiting coupling limiting a maximum input torque to the pump.
