    â€¢ The reverse gear
    â€¢ The differential output

The basic components of the 5-speed transaxle assembly units are the:

    â€¢ Transaxle case
    â€¢ Input shaft
    â€¢ Input shaft gears
    â€¢ Output shaft
    â€¢ Output shaft gears
    â€¢ Ring gear and differential assembly

Forward Gear

Shifting to a forward gear is accomplished through a combination of synchronizers with blocker rings controlled by sliding shift forks.

Reverse Gear

Reverse gear is not synchronized and uses a sliding idler gear arrangement.

Differential Assembly

The differential is a conventional arrangement of gears that is supported by tapered roller bearings. The final output gear turns the ring gear and differential assembly which turns the drive axle shafts.
