A manual transmission comprising an input shaft, and output shaft, an intermediate shaft having a transfer gear fixed thereto. First and second constant-mesh gearsets are supported between the input and output shafts and a f irst synchronizer clutch is provided for selectively engaging either of the first and second gearsets for drivably connecting the output shaft to the input shaft and establi sh first and second forward speed ratios therebetween. Third and fourth constant-mesh gearsets are supported between the input shaft and the intermediate shaft. A fi fth constant-mesh gearset is supported between the input and output shafts and is meshed with the transfer gear for drivably connecting the intermediate shaft to the output shaft. A second synchronizer clutch is provided for selectively engaging either of the third and fourth gearsets for drivably connecting the intermediate shaft to the input shaft for establishing third and fourth speed rations between the i nput shaft and output shaft. A sixth constant-mesh gearset is supported between the input and output shafts and a third synchronizer clutch is provided for selectiv ely engaging either of the fifth and sixth gearsets for drivably connecting the inpu t shaft to the output shaft for respectively establishing a fifth forward speed ration a nd a reverse speed ration therebetween. |
