THROTTLE VALVE CABLE ADJUSTMENT
PROCEDURE
The transmission throttle valve is operated by a
cam on the valve body throttle lever. The throttle
lever is actuated by a cable connected to the engine
throttle body lever.
The throttle valve is located within the transaxle
valve body and is responsible for transaxle shift
speed, shift quality, and part-throttle downshift sen-
sitivity. Proper cable adjustment is essential for
proper transaxle operation.
NOTE: The air cleaner/throttle body assembly must
be installed into position before making this adjust-
ment.
(1) Verify cable is routed properly with no kinked
or binding conditions.(2) Release adjustment locking clip on cable at
throttle body.It is not necessary to remove clip.
(3) Grab cable conduit near adjustment body, push
in towards throttle body, then release grip (Fig. 217).
This allows cable to self adjust.
(4) Press locking clip to secure cable position (Fig.
218).
(5) Road test vehicle to verify proper transaxle
operation.

BAND ADJUSTMENT
KICKDOWN BAND (FRONT)
The kickdown band adjusting screw is located on
left side (top front) of the transaxle case.
(1) Loosen locknut and back±off nut approximately
five turns. Test adjusting screw for free turning in
the transaxle case.
(2) Using wrench, tighten adjusting screw to 8
N´m (72 in. lbs.).
(3) Back±off adjusting screw the number of turns
listed in Specifications. Hold adjusting screw in this
position and tighten locknut to 47 N´m (35ft. lbs.)
LOW/REVERSE BAND (REAR)
To adjust low/reverse band, proceed as follows:
(1) Loosen and back off locknut approximately five
turns.
(2) Using an inch-pound torque wrench, tighten
adjusting screw to 5 N´m (41 in. lbs.) true torque.
(3) Back±off adjusting screw the number of turns
listed under Specifications. A chart is located at the
rear of this section.
(4) Tighten locknut to 14 N´m (10 ft. lbs.).
HYDRAULIC CONTROL PRESSURE
ADJUSTMENTS
LINE PRESSURE
An incorrect throttle pressure setting will cause
incorrect line pressure readings even though line
pressure adjustment is correct. Always inspect andcorrect throttle pressure adjustment before adjusting
the line pressure.
The approximate adjustment for line pressure is
1-5/16 inches, measured from valve body to inner
edge of adjusting nut. However, due to manufactur-
ing tolerances, the adjustment can be varied to
obtain specified line pressure.
The adjusting screw may be turned with an Allen
wrench. One complete turn of adjusting screw
changes closed throttle line pressure approximately
1-2/3 psi. Turning adjusting screw counterclockwise
increases pressure, and clockwise decreases pressure.
THROTTLE PRESSURE
Throttle pressures cannot be tested accurately;
therefore, the adjustment should be measured if a
malfunction is evident.
(1) Insert gauge pin of Tool C-3763 between the
throttle lever cam and kickdown valve.
(2) By pushing in on tool, compress kickdown
valve against its spring so throttle valve is com-
pletely bottomed inside the valve body.
(3) While compressing spring, turn throttle lever
stop screw with adapter C-4553. Turn until head of
screw touches throttle lever tang, with throttle lever
cam touching tool and throttle valve bottomed. Be
sure adjustment is made with spring fully com-
pressed and valve bottomed in the valve body.
BEARING ADJUSTMENT PROCEDURES
(1) Take extreme care when removing and install-
ing bearing cups and cones.Use only an arbor
press for installation, as a hammer may not
properly align the bearing cup or cone.Burrs or
nicks on the bearing seat will give a false end play
reading, while gauging for proper shims. Improperly
seated bearing cup and cones are subject to low-mile-
age failure.
(2) Bearing cups and cones should be replaced if
they show signs of pitting or heat distress.
(3) If distress is seen on either the cup or bearing
rollers, both cup and cone must be replaced.
NOTE: Bearing end play and drag torque specifica-
tions must be maintained to avoid premature bear-
ing failures.
(4) Used (original) bearing may lose up to 50 per-
cent of the original drag torque after break-in.
NOTE: All bearing adjustments must be made with
no other component interference or gear inter-
mesh, except the transfer gear bearing.
(5) Refer to the conversion chart in specifications
to convert inches to millimeter measurements. Refer
to bearing shim chart for proper shim thicknesses.

signals when the vehicle is equipped with Anti-Lock
Brakes.
The use of tires from different manufactures on the
same vehicle is NOT recommended. The proper tire
pressure should be maintained on all four tires.
SPARE TIRE±TEMPORARY
The temporary spare tire is designed for emer-
gency use only. The original tire should be repaired
or replaced at the first opportunity, then reinstalled.
Do not exceed speeds of 50 M. P. H. when using the
temporary spare tire. Refer to Owner's Manual for
complete details.
REPLACEMENT TIRES
The original equipment tires provide a proper bal-
ance of many characteristics such as:
²Ride
²Noise
²Handling
²Durability
²Tread life
²Traction
²Rolling resistance
²Speed capabilityIt is recommend that tires equivalent to the origi-
nal equipment tires be used when replacement is
needed.
Failure to use equivalent replacement tires may
adversely affect the safety and handling of the vehi-
cle.
The use of oversize tires may cause interference
with vehicle components. Under extremes of suspen-
sion and steering travel, interference with vehicle
components may cause tire damage.
WARNING: FAILURE TO EQUIP THE VEHICLE WITH
TIRES HAVING ADEQUATE SPEED CAPABILITY
CAN RESULT IN SUDDEN TIRE FAILURE.
DIAGNOSIS AND TESTING
TREAD WEAR INDICATORS
Tread wear indicators are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators will appear as a
13 mm (1/2 in.) band (Fig. 3).
Tire replacement is necessary when indicators
appear in two or more grooves or if localized balding
occurs.

DESCRIPTION AND OPERATION
WHEEL
Original equipment wheels are designed for proper
operation at all loads up to the specified maximum
vehicle capacity.All models use steel or cast aluminum drop center
wheels (Fig. 1). Every wheel has raised sections
between the rim flanges and rim drop well called
safety humps (Fig. 2).
Initial inflation of the tires forces the bead over
these raised sections. In case of air loss the raised

sections help hold the tire in position on the wheel
until the vehicle can be brought to a safe stop.
Cast aluminum wheels require special balance
weights to fit on the thicker flange of the rim and
special wheel clamps for the alignment equipment.
The wheel studs and nuts are designed for specific
wheel applications and must be replaced with equiv-
alent parts. Do not use replacement parts of lesser
quality or of a substitute design. All aluminum
wheels use wheel nuts with an enlarged nose. This
enlarged nose is necessary to ensure proper retention
of the wheels.
Vehicles that are equipped with lock-on wheel cov-
ers use large nose wheel nuts. The wheel nuts are
externally threaded so that the wheel covers can be
attached to the wheel nuts.
WHEEL COVER (LOCK-ON)
This vehicle uses a lock-on type wheel cover (Fig.
3) on certain models.
The wheel cover is attached to the wheel using the
5 nuts located in the wheel cover (Fig. 3). The nuts in
the wheel cover thread onto a special externally
threaded wheel nut (Fig. 4) to retain the wheel cover
to the wheel.
The wheel cover retaining nut (Fig. 3) is retained
in the wheel cover and will stay on the wheel cover
when un-threaded from the wheel nut. If required,
the retaining nut can be removed from the wheel
cover and replaced as a separate part of the wheel
cover.
The lock-on wheel cover can not be removed from
the wheel until all 5 wheel cover retaining nuts areun-threaded from the wheel nuts. Then the lock-on
wheel cover can be removed by hand from the wheel.DIAGNOSIS AND TESTING
WHEEL INSPECTION
Inspect wheels for:
²Excessive run out
²Dents or cracks
²Damaged wheel lug nut holes
²Air Leaks from any area or surface of the rim
NOTE: Do not attempt to repair a wheel by ham-
mering, heating or welding.
If a wheel is damaged an original equipment
replacement wheel should be used. When obtaining
replacement wheels, they should be equivalent in
load carrying capacity. The diameter, width, offset,
