GENERAL DESCRIPTION
AND SYSTEM OPERATION
FIVE–SPEED MANUAL TRANSAXLE
This five–speed transaxle assembly is a transmission of
constant–mesh design.
Combined in the assembly are:
S All forward gears.
S The reverse gear.
S The differential output.
The basic components of the five–speed transaxle as-
sembly units are the:
S Transaxle case.
S Input shaft.
S Input shaft gears.S Output shaft.
S Output shaft gears.
S Ring gear and differential assembly.
Forward Gear
Shifting to a forward gear is accomplished through a com-
bination 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 out-
put gear turns the ring gear and differential assembly
which turns the drive axle shafts.
