(4) Place valve body manual lever in low (1 posi-
tion) so ball on park lock rod will be easier to install
in sprag.
(5) Lubricate shaft of manual lever with petroleum
jelly. This will ease inserting shaft through seal in
case.
(6) Lubricate seal rings on valve body harness con-
nector with petroleum jelly.
(7) Position valve body in case and work end of
park lock rod into and through pawl sprag. Turn pro-
peller shaft to align sprag and park lock teeth if nec-
essary. The rod will click as it enters pawl. Move rod

or two bolts to hold valve body in place.
(11) Tighten valve body bolts alternately and
evenly to 11 N´m (100 in. lbs.) torque.
(12) Install new fluid filter on valve body. Tighten
filter screws to 4 N´m (35 in. lbs.) torque.
(13) Install throttle and gearshift levers on valve
body manual lever shaft.
(14) Check and adjust front and rear bands if nec-
essary.
(15) Connect solenoid case connector wires.
(16) Install oil pan and new gasket. Tighten pan
bolts to 13.6 N´m (125 in. lbs.) torque.
(17) Lower vehicle and fill transmission with
MopartATF +4, type 9602, fluid.
(18) Check and adjust gearshift and throttle valve
cables, if necessary.
ADJUSTMENTS - VALVE BODY
CONTROL PRESSURE ADJUSTMENTS
There are two control pressure adjustments on the
valve body;
²Line Pressure
²Throttle Pressure
Line and throttle pressures are interdependent
because each affects shift quality and timing. As a
result, both adjustments must be performed properly
and in the correct sequence. Adjust line pressure first
and throttle pressure last.

LINE PRESSURE ADJUSTMENT
Measure distance from the valve body to the inner
edge of the adjusting screw with an accurate steel
scale (Fig. 318).
Distance should be 33.4 mm (1-5/16 in.).
If adjustment is required, turn the adjusting screw
in, or out, to obtain required distance setting.
NOTE: The 33.4 mm (1-5/16 in.) setting is an
approximate setting. Manufacturing tolerances may
make it necessary to vary from this dimension to
obtain desired pressure.
One complete turn of the adjusting screw changes
line pressure approximately 1-2/3 psi (9 kPa).
Turning the adjusting screw counterclockwise
increases pressure while turning the screw clockwise
decreases pressure.THROTTLE PRESSURE ADJUSTMENT
Insert Gauge Tool C-3763 between the throttle
lever cam and the kickdown valve stem (Fig. 319).
Push the gauge tool inward to compress the kick-
down valve against the spring and bottom the throt-
tle valve.
Maintain pressure against kickdown valve spring.
Turn throttle lever stop screw until the screw head
touches throttle lever tang and the throttle lever cam
touches gauge tool.
NOTE: The kickdown valve spring must be fully
compressed and the kickdown valve completely
bottomed to obtain correct adjustment.

exception being when the road surface is covered by
ice and snow.
The low range reduction gear system is operative
in 4LO range only. This range is for extra pulling
power in off road situations. Low range reduction
ratio is 2.72:1.
A front axle disconnect system is used to achieve
two-wheel drive mode. The axle disconnect vacuum
motor is actuated by a vacuum switch on the transfer
case. The switch is operated by the transfer case
range rod.
SHIFT MECHANISM
The transfer case is operated by an adjustable floor
mounted shift linkage. The transfer case shift lever
is directly attached to the shift sector. The sector
operates the range and mode forks within the trans-
fer case.
A straight line shift pattern is used with a NEU-
TRAL detent. Lever range positions are imprinted in
the shift knob.
SHIFTING
The synchronizer components allow the transfer
case to be shifted between the 2H and 4H operating
ranges while the vehicle is in motion. The vehicle
must have the transmission placed in NEUTRAL, or
the clutch depressed in the case of a manual trans-
mission, and be moving less than 2-3 MPH when
shifting into the 4L operating range.
DIAGNOSIS AND TESTING - TRANSFER CASE
Before beginning repair on a suspected transfer
case malfunction, check all other driveline compo-
nents beforehand.
The actual cause of a problem may be related to
such items as: front hubs, axles, propeller shafts,
wheels and tires, transmission, or clutch instead. If
all other driveline components are in good condition
and operating properly, refer to the Diagnosis Chart
for further information.

INSTRUMENT PANEL SYSTEM
DESCRIPTION
The instrument panel is located at the front of the
passenger compartment. This instrument panel is
molded from a blend of various plastics that are
mechanically attached to the vehicle. Colors are
molded into the plastic components to minimize
appearance degradation from scratches or abrasions.
The panel components are internally ribbed and riv-
eted to steel reinforcements for additional structural
integrity and dimensional stability. The instrument
panel surface components are designed to deform
upon impact without breaking. This type of construc-
tion provides improved energy absorption which, in
conjunction with the dual airbags and seat belts,
helps to improve occupant protection.
The top of the instrument panel is secured to the
top of the dash panel near the base of the windshield
using screws. An end bracket integral to each end of
the instrument panel structure is secured to each
cowl side inner panel with a screw. A stamped metal
bracket supports the center of the instrument panel
by securing it to the top of the floor panel transmis-
sion tunnel below the instrument panel with screws.
The instrument cluster, radio, heater-air conditioner
control, passenger airbag, glove box, electrical junc-tion block, Central Timer Module (CTM), accessory
switches, ash receiver, cigar lighter, accessory power
outlet, park brake release handle, inside hood release
handle, as well as numerous other components are
secured to and supported by this unit.
The instrument panel for this vehicle includes the
following major features:
²Cluster Bezel- This molded plastic bezel is
secured with snap clips to the instrument panel sup-
porting structure. It trims out the edges of the head-
lamp switch, instrument cluster, radio, heater-air
conditioner controls, passenger airbag on-off switch,
and the heated seat switches on vehicles so equipped.
On vehicles without the heated seat option, a small
storage cubby bin is provided in the cluster bezel.
This bezel also incorporates three completely adjust-
able panel outlets for the climate control system, and
fills the opening between the instrument cluster and
the top of the steering column where it passes
through the instrument panel.
²Cup Holder/Storage Bin- Vehicles equipped
with an automatic transmission feature a latching
fold-down, adjustable cup holder located on the lower
instrument panel between the glove box and the ash
receiver. Vehicles equipped with a manual transmis-
sion have a lighted storage bin on the instrument
panel in place of the cup holder.
