Abstract
A countershaft transmission provides three forward speeds and three reverse speeds using an input shaft, an output shaft, an intermediate shaft, five rotating clutch assemblies of the interleaved multiple plate and disc type, and eight gears. The first speed clutch assembly is mounted on the intermediate shaft, the second and third speed clutch assemblies are mounted on the output shaft, the remaining directional clutch assemblies are mounted on the input shaft, and the clutch assemblies are generally compactly grouped. Advantageously, no separate idler gear and associated shaft are required.
