CLEANING AND INSPECTION
TRANSAXLE
Clean the gears, bearings, shafts, synchronizers,
thrust washers, oil feeder, shift mechanism, gear
case, and bellhousing with solvent. Dry all parts
except the bearings with compressed air. Allow the
bearings to either air dry or wipe them dry with
clean shop towels.
Inspect the gears, bearings, shafts and thrust
washers. Replace the bearings and cups if the rollers
are worn, chipped, cracked, flat spotted, or brin-
nelled, or if the bearing cage is damaged or distorted.
Replace the thrust washers if cracked, chipped, or
worn. Replace the gears if the teeth are chipped,
cracked, or worn thin. Inspect the synchronizers.
Replace the sleeve if worn or damaged in any way.
Replace the stop rings if the friction material is
burned, flaking off, or worn. Check the condition of
the synchro keys and springs. Replace these parts if
worn, cracked, or distorted.
SYNCHRONIZER
CLEAN
Do not attempt to clean the blocking rings in sol-
vent. The friction material will become contaminated.
Place synchronizer components in a suitable holder
and clean with solvent. Air dry.
INSPECT
Proper inspection of components involve:
²Teeth, for wear, scuffed, nicked, burred, or bro-
ken teeth
²Keys, for wear or distortion
²Balls and springs, for distortion, cracks, or wear
If any of these conditions exist in these compo-
nents, replace as necessary.
ADJUSTMENTS
GEARSHIFT CROSSOVER CABLE
(1) Remove shift console from vehicle.
(2) Loosen adjusting screw on crossover cable at
shifter (Fig. 136).(3) Pin transaxle crossover lever in 3-4 neutral
position using a 1/4 inch drill bit. Align hole in cross-
over lever with the hole in the boss on the transaxle
case (Fig. 137). Be sure drill bit goes into transaxle
case at least one±half inch.
(4) The shifter is spring±loaded and self±centering.
Allow shifter to rest in its neutral position. Torque
adjustment screw to 8 N´m (70 in. lbs.). Care must be
taken to avoid moving the shift mechanism off-center
during screw tightening.
(5) Remove drill bit from transaxle case and per-
form functional check by shifting transaxle into all
gears.
(6) Reinstall center shift console. Blouse boot out

(8) Recheck fluid level after transaxle is at normal
operating temperature. The level should be in the
HOT region.
ALUMINUM THREAD REPAIR
Damaged or worn threads in the aluminum tran-
saxle case and valve body can be repaired by the use
of Heli-Coils. This repair consists of drilling out the
worn-out or damaged threads. Then tap the hole with
a Heli-Coil tap, and install a Heli-Coil insert into the
hole. This brings the hole back to its original thread
size.
Heli-Coil tools and inserts are readily available
from most automotive parts suppliers.
FLUSHING COOLERS AND TUBES
When a transaxle failure has contaminated the
fluid, the oil cooler(s) must be flushed. The cooler
bypass valve in the transaxle must be replaced also.
The torque converter must also be replaced with an
exchange unit. This will ensure that metal particles
or sludged oil are not later transferred back into the
reconditioned (or replaced) transaxle.
The recommended procedure for flushing the cool-
ers and tubes is to use Tool 6906A Cooler Flusher.

INSPECTION
Inspect facing material on all driving discs.
Replace discs that are charred, glazed, or heavily pit-
ted. Discs should also be replaced if they show evi-
dence of material flaking off, or if facing material can
be scraped off easily. Inspect driving disc splines for
wear or other damage. Inspect steel plate and pres-
sure plate surface for burning, scoring, or damaged
driving lugs. Replace if necessary. Inspect plates and
discs for flatness; they must not be warped or cone-
shaped.
Inspect steel plate lug grooves in clutch retainer
for smooth surfaces; plates must travel freely in the
grooves. Note ball check in piston; be sure ball moves
freely. Inspect seal rings surfaces in clutch retainer
for nicks or deep scratches; light scratches will not
interfere with sealing of the seals. Inspect Neoprene
seal rings for deterioration, wear, and hardness.

To remove the differential bearing cup from the
extension housing/adapter side, use Special Tool
6062A, Remover. To install the differential bearing
cup on the extension housing/adapter side, use Spe-
cial Tool 6536, Driver and Special Tool C-4171, Han-
dle.
DETERMINING SHIM THICKNESS
Shim thickness need be determined only if any of
the following parts are replaced:
²Transaxle case
²Differential carrier
²Differential bearing retainer
²Extension housing
²Differential bearing cups and cones
Refer to Bearing Adjustment Procedure in rear of
this section to determine proper shim thickness.
CLEANING AND INSPECTION
VALVE BODY
Allow all parts to soak a few minutes in a suitable
clean solvent. Wash thoroughly and blow dry with
compressed air. Be sure all passages are clean and
free from obstructions.
Inspect manual and throttle valve operating levers
and shafts for being bent, worn or loose. If a lever is
loose on its shaft, it should be replaced. Do not
attempt to straighten bent levers.
Inspect all mating surfaces for burrs, nicks and
scratches. Minor blemishes may be removed with cro-
cus cloth, using only a very light pressure. Using a
straightedge, inspect all mating surfaces for warpage
or distortion. Slight distortion may be corrected,
using a surface plate. Be sure all metering holes in
steel plate are open. Using a penlight, inspect bores
in valve body for scores, scratches, pits, and irregu-
larities.
Inspect all valve springs for distortion and col-
lapsed coils. Inspect all valves and plugs for burrs,
nicks, and scores. Small nicks and scores may be
removed with crocus cloth, providing extreme care is
taken not to round off sharp edges. The sharpness of
these edges is vitally important. It prevents foreign
matter from lodging between valve and valve body.
This reduces the possibility of sticking. Inspect all
valves and plugs for freedom of operation in valve
body bores.
When bores, valves, and plugs are clean and dry,
the valves and plugs should fall freely in the bores.
The valve body bores do not change their dimensions
with use. Therefore, a valve body that was function-
ing properly when vehicle was new, will operate cor-
rectly if it is properly and thoroughly cleaned. There
is no need to replace a valve body unless it is dam-
aged in handling.
ADJUSTMENTS
GEARSHIFT CABLE
Normal operation of the Park/Neutral Position
Switch provides a quick check to confirm proper link-
age adjustment.
Move the selector level slowly forward until it
clicks into the PARK (P) position. The starter should
operate.
After checking the (P) position, move selector
slowly toward the NEUTRAL (N) position until lever
drops in the (N) position. If the starter will operate
also at this point, the gearshift linkage is properly
adjusted. If the starter fails to operate in either posi-
tion, linkage adjustment is required.

ADJUSTMENT
(1) Set parking brake.
(2) Remove floor console. Refer to Group 23, Body.
(3) Place gearshift lever in the (PARK) (P) posi-
tion.
(4) Push down on the tab and unsnap the collar at
the shifter cable to allow the cable to be adjusted
(Fig. 196).
(5) Move the gearshift lever on the transaxle to
the PARKposition.
(6) Verify the shift lever and transaxle are in the
PARK position. Rotate collar on the shift cable
adjuster end up until it seats against the plastic
housing. NOTE: If the collar will not rotate to the
fully detented lock position, rotate the collar back to
its initial unlocked position. Position the ATX in the
gated PARK position. Apply a slight load to the shift
lever, fore or aft in vehicle, while simultaneously
rotating the collar upward to the LOCK position. The
collar must seat against the plastic housing to
achieve the required detented lock position. The gear-
shift linkage should now be properly adjusted.
Check adjustment as follows:
(7) Detent position for NEUTRAL and DRIVE
should be within limits of hand lever gate stops.
(8) Key start must occur only when the shift lever
is in PARK or NEUTRAL positions.
THROTTLE PRESSURE CABLE ADJUSTMENT
PROCEDURE
The throttle pressure cable adjustment is very
important to proper transaxle operation. This adjust-
ment positions a valve which controls shift speed,
shift quality, and part throttle downshift sensitivity.
If the setting is too long, early shifts and slippage
between shifts may occur. If the setting is too short,
shifts may be delayed and part throttle downshifts
may be very sensitive.(1) Perform transaxle throttle pressure cable
adjustment while engine is at normal operating tem-
perature.
(2) Release cross-lock on the cable assembly (pull
cross-lock upward) see (Fig. 197).
(3) To ensure proper adjustment, the cable must be
free to slide all the way toward the engine, against
its stop, after the cross-lock is released.
(4) Move transaxle throttle control lever fully
clockwise, against its internal stop, and press cross-
lock downward into locked position.
The adjustment is complete and transaxle throttle
cable backlash was automatically removed.
Test cable freedom of operation by moving the
transaxle throttle lever forward (counterclockwise).
Then slowly release it to confirm it will return fully
rearward (clockwise).
No lubrication is required for any component of the
throttle cable system.
SHIFTER/IGNITION INTERLOCK SYSTEM
If ignition switch cannot be turned to the LOCK
position, with shifter in PARK, an adjustment of the
Interlock System may be required. To adjust Shifter/
Ignition Interlock System, follow procedure listed
below.
(1) Disconnect and isolate, the battery negative (-)
cable from the vehicle battery.
(2) Remove console assembly. Refer to Group 23,
Body.
(3) Remove the gearshift knob set screw and knob.
(4) Remove the screws retaining the gearshift indi-
cator bezel and remove bezel and indicator lamp.
(5) Reinstall the gearshift knob.
(6) Place shifter in PARK.
(7) Turn ignition switch to the LOCK or ACCES-
SORY position. If cable has lost its adjustment, man-
ually position cable to get key into LOCK or
ACCESSORY position. Grasp slug on interlock cable

DIAGNOSIS AND TESTING
WATER LEAKS
Water leaks can be caused by poor sealing,
improper body component alignment, body seam
porosity, missing plugs, or blocked drain holes. Cen-
trifugal and gravitational force can cause water to
drip from a location away from the actual leak point,
making leak detection difficult. All body sealing
points should be water tight in normal wet-driving
conditions. Water flowing downward from the front of
the vehicle should not enter the passenger or luggage
compartment. Moving sealing surfaces will not
always seal water tight under all conditions. At
times, side glass or door seals will allow water to
enter the passenger compartment during high pres-
sure washing or hard driving rain (severe) condi-
tions. Overcompensating on door or glass
adjustments to stop a water leak that occurs under
severe conditions can cause premature seal wear and
excessive closing or latching effort. After completing
a repair, water-test vehicle to verify leak has stopped
before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK
TESTS
Verify that floor and body plugs are in place, body
drains are clear, and body components are properly
aligned and sealed. If component alignment or seal-
ing is necessary, refer to the appropriate section of
this group for proper procedures.
WATER LEAK TESTS
WARNING: DO NOT USE ELECTRIC SHOP LIGHTS
OR TOOLS IN WATER TEST AREA. PERSONAL
INJURY CAN RESULT.
When the conditions causing a water leak have
been determined, simulate the conditions as closely
as possible.
²If a leak occurs with the vehicle parked in a
steady light rain, flood the leak area with an open-
ended garden hose.
²If a leak occurs while driving at highway speeds
in a steady rain, test the leak area with a reasonable
velocity stream or fan spray of water. Direct the
spray in a direction comparable to actual conditions.
²If a leak occurs when the vehicle is parked on an
incline, hoist the end or side of the vehicle to simu-
late this condition. This method can be used when
the leak occurs when the vehicle accelerates, stops or
turns. If the leak occurs on acceleration, hoist the
front of the vehicle. If the leak occurs when braking,
hoist the back of the vehicle. If the leak occurs on left
turns, hoist the left side of the vehicle. If the leak
occurs on right turns, hoist the right side of the vehi-cle. For hoisting recommendations refer to Group 0,
Lubrication and Maintenance, General Information
section.
WATER LEAK DETECTION
To detect a water leak point-of-entry, do a water
test and watch for water tracks or droplets forming
on the inside of the vehicle. If necessary, remove inte-
rior trim covers or panels to gain visual access to the
leak area. If the hose cannot be positioned without
being held, have someone help do the water test.
Some water leaks must be tested for a considerable
length of time to become apparent. When a leak
appears, find the highest point of the water track or
drop. The highest point usually will show the point of
entry. After leak point has been found, repair the
leak and water test to verify that the leak has
stopped.
Locating the entry point of water that is leaking
into a cavity between panels can be difficult. The
trapped water may splash or run from the cavity,
often at a distance from the entry point. Most water
leaks of this type become apparent after accelerating,
stopping, turning, or when on an incline.
MIRROR INSPECTION METHOD
When a leak point area is visually obstructed, use
a suitable mirror to gain visual access. A mirror can
also be used to deflect light to a limited-access area
to assist in locating a leak point.
BRIGHT LIGHT LEAK TEST METHOD
Some water leaks in the luggage compartment can
be detected without water testing. Position the vehi-
cle in a brightly lit area. From inside the darkened
luggage compartment inspect around seals and body
seams. If necessary, have a helper direct a drop light
over the suspected leak areas around the luggage
compartment. If light is visible through a normally
sealed location, water could enter through the open-
ing.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compart-
ment cannot be detected by water testing, pressurize
the passenger compartment and soap test exterior of
the vehicle. To pressurize the passenger compart-
ment, close all doors and windows, start engine, and
set heater control to high blower in HEAT position. If
engine can not be started, connect a charger to the
battery to ensure adequate voltage to the blower.
With interior pressurized, apply dish detergent solu-
tion to suspected leak area on the exterior of the
vehicle. Apply detergent solution with spray device or
soft bristle brush. If soap bubbles occur at a body
seam, joint, seal or gasket, the leak entry point could
be at that location.
