Abstract
A multispeed power transmission has an input shaft, a pair of parallel transfer shafts, a differential gear set and a pair of output shafts. The output shafts extend from opposite sides of the differential gear set and are disposed coaxial with one of the transfer shafts and the input shaft. An output gear set is connected for torque transfer between the other transfer shaft and the differential gear set. A plurality of clutch controlled ratio gears sets are connectible between the transfer shafts to provide selective gear ratios therebetween. A direct clutch provides selective connection between the one transfer shaft and the differential gear set in bypass relation with the output gear set. A forward clutch is selectively operable in combination with the clutch controlled ratio gear sets and a direct clutch to provide a plurality of drive paths between the input shaft and the differential gear set. A clutch controlled reverse gear set is selectively operable to provide a reversing drive path between the input shaft and the differential gear set.
