7A2-2 MANUAL TRANSAXLE (M13 ENGINE)
General Description
Manual Transaxle Construction and Servicing
The transaxle provides five forward speeds and one reverse speed by means of three synchronizers and three
shafts-input shaft, countershaft and reverse gear shaft. All forward gears are in constant mesh, and reverse
uses a sliding idler gear arrangement.
The low speed synchronizer is mounted on counter shaft and engaged with counter shaft first gear or second
gear, while the high speed synchronizer is done on input shaft and engaged with input shaft third gear or fourth
gear.
The fifth speed synchronizer on input shaft is engaged with input shaft fifth gear mounted on the input shaft.
The double cone synchronizing mechanism is provided to 2nd gear synchromesh device for high performance
of shifting to 2nd gear.
The countershaft turns the final gear and differential assembly, thereby turning the front drive shafts which are
attached to the front wheels.
4WD model is equipped with transfer assembly on transaxle being mated to right side of differential output in
transaxle.
For servicing, it is necessary to use genuine sealant or its equivalent on mating surfaces of transaxle case which
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 reas-
sembling.
Further, care must be taken to adjust preload of counter shaft taper roller bearings. New synchronizer rings are
prohibited from being lapped with respective gear cones by using lapping compound before they are assembled.
