Beschreibung
Zusammenfassung:	A transmission to transfer power from an electric motor to first and second axles of a vehicle includes an input shaft adapted to be driven by the electric motor and a first planetary gear set. A second planetary gear set has a first member driven by the first planetary gear set, a second member restricted from rotation and a third member. A differential assembly has a first side gear adapted to drive the first axle, a second side gear adapted to drive the second axle and a pair of pinion gears meshed with the first and second side gears. A first clutch is operable to drivingly interconnect the first member and the differential assembly. A second clutch is operable to drivingly interconnect the third member and the differential assembly.
