This 5-speed transaxle assembly is a transmission of constant mesh design.

Combined in the assembly are:

    • All forward gears
    • The reverse gear
    • The differential output

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

    • Transaxle case
    • Input shaft
    • Input shaft gears
    • Output shaft
    • Output shaft gears
    • 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.
