A manual transmission (10) comprising an input shaft (14), an output shaft (20), an intermediate shaft (26) having a transfer gear (92) fixed thereto. First (60) and second (66) constant-mesh gearsets are supported between the input (14) and output (20) shafts and a first synchronizer clutch (106) is provided for selectively engaging either of the first (60) and second (66) gearsets for drivably connecting the output shaft (20) to the input shaft (14) and establish first and second forward speed ratios therebetween. Third (72) and fourth (78) constant-mesh gearsets are supported between the input shaft (14) and the intermediate shaft (26). A fifth (84) constant-mesh gearset is supported between the input (14) and output shafts (20) and is meshed with the transfer gear (92) for drivably connecting the intermediate shaft (26) to the output shaft (20). A second synchronizer clutch (116) is provided for selectively engaging either of the third (72) and fourth (78) gearsets for drivably connecting the intermediate shaft (26) to the input shaft (14) for establishing third and fourth speed ratios between the input shaft and output shaft. A sixth constant-mesh gearset (94) is supported between the input (14) and output (20) shafts and a third synchronizer clutch (124) is provided for selectively engaging either of the fifth (84) and sixth (94) gearsets for drivably connecting the input shaft (14) to the output shaft (20) for respectively establishing a fifth forward speed ratio and a reverse speed ratio therebetween. |
