A manual transmission comprising an input shaft, an 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 first 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 establish first and second foward speed ratios therebetween. Third and fourth constant-mesh gearsets are supported between the input shaft and the intermediate shaft. A fifth 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 thid and foruth speed ratios between the input 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 selectively engaging either of the fifth and sixth gearsets for drivably connecting the input shaft to the output shaft for respectively establishing a fifth forward speed ratio and a reverse speed ratio therebetween. |
