Abstract
A power transmission has an input shaft, an output shaft and a transfer or secondary input shaft disposed on parallel noncoaxial axes. A transfer gear train including a gear member supported on each axis is connectible to the input shaft through a forward friction clutch for drivingly connecting the input shaft and the transfer shaft through a one-way drive connection to the output shaft. The transfer gear train provides the first and lowest forward drive ratio between the input and output shafts through the one-way drive connection. A plurality of friction clutches on the input and transfer shafts and associated reaction gears on the shafts are selectively operable to provide a plurality of higher forward ratios during which the one-way device permits the output shaft to overcome the transfer gear mounted thereon.
