Abstract
A compact manual transmission includes an input shaft having four fixed input gears, a first intermediate shaft rotatably supporting two speed gears meshing with two of the input gears, a second intermediate shaft rotatably supporting three speed gears meshed with three of the input gears and a reverse gear meshed with a speed gear on the first intermediate shaft, and an output shaft. Two speed gears on each of the intermediate shafts meshes with common input gears. A transfer gear on each intermediate shaft is meshed with the output shaft. The transmission further includes a synchronizer clutch for establishing two forward gears by selectively coupling the two speed gears to the first intermediate shaft and a pair of synchronizer clutches for establishing three forward gears and the reverse gear by selectively coupling the three speed gears and reverse gear to the second intermediate shaft.
