A second cavity is adapted to be selectively supplied with pressurized fluid to provide cooling to the multi-disk clutch pack. A first fluid passage adapted to provide pressurized fluid to the first cavity, and a second fluid passage is adapted to provide pressurized fluid to the second fluid passage.
