Manual Transmission/Transaxle: Description and Operation

E55F5 And E57F5 Transaxle:

- The E55F5 and E57F5 transaxle has been made compact by arranging the transmission, the center differential, the front differential and the transfer on the same quadruple case axle.
- The center differential, which compensates for the difference between the rotation speed of the front and rear wheels, provide durability and reliability by utilizing bevel gear to distributing the engine power from the transmission to both the front and rear propeller shafts in a 50/50 split. This center differential has been equipped with a lock mechanism which enables the vehicle to get out of the trouble spot more easily when one of the four wheels spins in the deep snow or muddy roads, etc.
