| 1. A device for transferring power flow between a multidisplacement engine and a transmission comprising:
an enclosed housing having a first shell on the engine side and nonrotatably connected to the drive shaft/crankshaft of the
engine, a second shell on the transmission side, and an axis of rotation, said housing being at least partially filled with
oil and connected to an oil pump outside said housing;
an opening on said second shell for receiving a transmission input shaft from said transmission;
a hub located within said housing, said hub nonrotatably connected to said transmission input shaft;
a planetary gear set comprising an outer ring gear, a set of intermediate planet gears contained within a planet carrier,
and a sun gear attached to a stator;
a first clutch pack comprising a plurality of friction discs connecting said housing and said ring gear when engaged;
a piston means said piston means designed to engage said first clutch pack;
a second clutch pack comprising a plurality of friction plates, said second clutch pack connecting said ring gear with said
sun gear when engaged;
a preloaded diaphragm spring connecting said second clutch pack with said ring gear;
