The transaxle provides five forward speeds and one reverse speed by means of three synchronizers and three
shafts-cluster gear (input shaft), main shaft and reverse gear shaft. All forward gears are in constant mesh, and
reverse uses a sliding idler gear arrangement.
The 1st and 2nd speed synchronizer is mounted on main shaft and engaged with main shaft 1st gear or 2nd
gear, also the 3rd and 4th speed synchronizer is done on main shaft and engaged with main shaft third gear or
4th gear.

attached to the front wheels.

is made of aluminum. The case fastening bolts must be tightened to specified torque by means of torque
wrench. It is also important that all parts are thoroughly cleaned with cleaning fluid and air dried before reassem-
bling.
New synchronizer rings are prohibited from being lapped with respective gear cones by using lapping com-
pound before they are assembled.
