ABSTRACT:
A manual transmission comprises a primary shaft and first and second secondary shafts placed parallel with the primary shaft. First speed, second speed, fifth speed and reverse idling gears are rotatably mounted on the first secondary shaft. A first double synchronizer is mounted on the first secondary shaft between the first speed idling gear and the second speed idling gear. A second double synchronizer is mounted on the first secondary shaft between the fifth speed idling gear and the reverse idling gear. Third and fourth speed idling gears are rotatably mounted on the second secondary shaft. A third double synchronizer is mounted on the second secondary shaft between the third speed idling gear and the fourth speed idling gear. A third speed gear is mounted on the primary shaft and meshes with the third speed idling gear, the third speed gear being axially positioned between the teeth of the reverse idling gear and the second double synchronizer. A fourth speed gear is mounted on the primary shaft and drivingly meshes with both the fourth speed idling gear and the fifth speed idling gear. A reverse intermediate gear is mounted on a fixed intermediate pin and meshes with the reverse idling gear.
