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.

CLUTCH RELEASE POINT
ADJUSTMENT
Adjustment Procedure
1. Apply the parking brake.
2. Run the engine at idle speed.
3. While you move the shift lever into the reverse
position, depress the clutch pedal slowly and mea-
sure the distance between the point when gear
noise is not heard and the point the clutch pedal is
completely depressed. The distance should be 30
to 40 mm (1.2 to 1.6 inches).
4. If the distance is not within the specified value,
check the following:
S Clutch pedal height
S Clutch pedal play
S Air in the system
S Clutch cover and disc pressure plate
AIR BLEEDING
Bleed the hydraulic system to remove the air which en-
tered when the pipes were disconnected for repairs. The
clutch/brake fluid in the clutch/brake reservoir must be
maintained at the MIN level or higher during air bleeding.
1. Attach a vinyl hose to the bleeder plug. Place the
other end of the vinyl tube in a glass container half–
filled with brake fluid.
2. Slowly pump the clutch pedal several times.
3. While you press the clutch pedal, loosen the bleed-
er screw until the fluid starts to run out. Close the
bleeder screw.
4. Repeat Step 3 until there are no air bubbles in the
fluid.
5. Fill the reservoir with brake fluid up to the proper
level.
PRESSURE PLATE AND CLUTCH
DISC
Removal Procedure
1. Disconnect the negative battery cable.
2. Remove the transaxle from the vehicle. Refer to
Section 5B, Five–Speed Manual Transaxle.
3. Remove the pressure plate bolts and the pressure
plate.
Important : Support the pressure plate when you remove
the last bolt.
