ABSTRACT:
The transmission and clutch assembly including a conventional casing, a slidable input shaft directly engageable to the drive member for high gear, and further including an output shaft which is rotatably engaged in the open end of the input shaft, and further including a countershaft for change speed mode and reverse speed, a reverse speed shaft, a clutch housing, a clutch shaft connected to the clutch housing, a pair of pressure members, and a throw-out bearing for change speed mode including reverse speed. This transmission and clutch assembly does not use any internal oil pressure to effect changing of gears and substantially reduces the rotating weight of the transmission when the vehicle is in high gear, because the clutch housing, clutch shaft, input gear and pressure members do not rotate when the transmission is in direct drive speed mode unlike other known transmissions.
