Manual Transaxle Construction

The transaxle provides six forward speeds and one reverse speed with four synchromesh devices and three shafts: input shaft, countershaft and reverse gear shaft.

The low speed sleeve & hub is mounted on countershaft and engaged with countershaft 1st gear or 2nd gear, while the high speed sleeve & hub is mounted on input shaft and engaged with input shaft 3rd gear or 4th gear. The 5th & 6th speed sleeve & hub is mounted on input shaft and engaged with input shaft 5th gear or 6th gear. The reverse gear sleeve & hub is mounted on reverse gear shaft and engaged with reverse idler left gear or reverse idler right gear.

The triple cone synchronizing mechanism is provided to 1st and 2nd gear synchromesh devices for high performance of shifting to 2nd gear in particular. The double cone synchronizing mechanism is provided to 3rd gear synchromesh device for high performance of shifting to 3rd gear.

The gear shift control lever provides a pull-up-for-reverse mechanism. Pulling up the reverse inhibit ring under the gear shift control lever knob releases the selection restriction and allows shifting of the gear to reverse.

For servicing, it is necessary to use genuine sealant or its equivalent on mating surfaces of transaxle case. It is also important that all parts are thoroughly cleaned with cleaning fluid and air-dried before reassembling.

Further, care must be taken to adjust between case and shaft to thrust clearance of input shaft and countershaft. Synchronizer rings are inhibited from being lapped with respective gear cones using lapping compound before they are assembled.
