CHECKING FLUID LEVEL AND CONDITION
Recommended fluid for AW-4 transmissions is Mo-
par Dexron IIE/Mercon.
Mopar Dexron II can also be used but only when
Mercon fluid is not available.
CHECKING FLUID LEVEL
(1) Be sure transmission fluid is at normal operat-
ing temperature. Normal operating temperature is
reached after approximately 15 miles (25 km) of op-
eration.
(2) Position vehicle on level surface. This is impor-
tant for an accurate fluid level check.
(3) Shift transmission through all gear ranges and
back to Park.
(4) Apply parking brakes.
(5) Verify that transmission is in Park.
(6) Wipe off dipstick handle to prevent dirt from
entering fill tube. Then remove dipstick and check
fluid level and condition.
(7) Correct fluid level isto FULL mark on dip-
stick when fluid is at normal operating temper-
ature(Fig. 1).
(8) If fluid level is low, top off level with Mopar
Dexron IIE/Mercon. Mopar Dexron II can be used but
only if Mercon is not available.Do not overfill
transmission. Add only enough fluid to bring
level to Full mark.
(9) If too much fluid was added, excess amount can
be removed with suction gun and appropriate diame-
ter plastic tubing. Tubing only has to be long enough
to extend into oil pan.
CHECKING FLUID CONDITION
Inspect the appearance of the fluid during the fluid
level check. Fluid color should range from dark red to
pink and be free of foreign material, or particles. If
the fluid is dark brown or black in color and smells
burnt, the fluid has been overheated and must be
changed.Transmission operation should also be checked if
the fluid is severely discolored and contains quanti-
ties of foreign material, metal particles, or clutch disc
friction material.
A small quantity of friction material or metal
particles in the oil pan is normal. The particles
are usually generated during the break-in pe-
riod and indicate normal seating of the various
transmission components.
REFILLING AFTER OVERHAUL OR FLUID/FILTER
CHANGE
The best way to refill the transmission after a fluid
change or overhaul is as follows:
(1) If transmission has been overhauled, install
transmission in vehicle.
(2) Remove dipstick and insert clean funnel in
transmission fill tube.
(3) Add following initial quantity of Mopar Dexron
IIE/Mercon to transmission:
(a) If fluid/filter change was performed, add4
pints (2 quarts)of fluid to transmission.
(b) If transmission was completely overhauled
and torque converter was replaced or drained, add
10 pints (5 quarts)of fluid to transmission.
(c) Remove funnel and install dipstick.
(4) Operate vehicle until fluid reaches normal op-
erating temperature.
(5) Apply parking brakes.

21 - 182 AW-4 IN-VEHICLE SERVICEJ

(6) Let engine run at normal curb idle speed, apply
service brakes. Then shift transmission through all
gear ranges and back to PARK (leave engine run-
ning).
(7) Remove dipstick and check fluid level. Add only
enough fluid to bring level to Full mark on dipstick.
Do not overfill.If too much fluid is added, excess
amount can be removed with suction gun and
plastic tubing. Tubing only has to be long
enough to extend into oil pan.
(8) When fluid level is correct, shut engine off, re-
lease park brake, remove funnel, and reseat dipstick
in fill tube.
TRANSMISSION CONTROL MODULE (TCM)
SERVICE
Use the DRB scan tool to diagnose transmission
control module function whenever a fault is sus-
pected. Replace the module only when the scan tool
indicates the module is actually faulty.
TRANSMISSION CONTROL MODULE
REPLACEMENT
The transmission control module is mounted under
the instrument panel. On left hand drive models, it is
at the driver side of the lower finish panel (Fig. 2).
On right hand drive models, it is at the passenger
side of the lower finish panel (Fig. 3).
To remove the module, disconnect the wire harness,
remove the mounting screws and remove the module
from the finish panel. Tighten the module mounting
screws securely after installation. Also be sure the
wire harness is not twisted, kinked or touching any
body panels.
PARK/NEUTRAL POSITION SWITCH
SWITCH TESTING
Test switch continuity with an ohmmeter. Discon-
nect the switch and check continuity at the connector
terminal positions and in the gear ranges indicated
in Figure 3. Switch continuity should be as follows:
²Continuity should exist between terminals B and
C with the transmission in Park and Neutral only
(Fig. 4).²Continuity should exist between terminals A and E
with the transmission in Reverse (Fig. 4).
²Continuity should exist between terminals A and
G with the transmission in third gear (Fig. 4).
²Continuity should exist between terminals A and
H with the transmission in first and/or second gear
(Fig. 4).
²Continuity should not exist in D position.
PARK/NEUTRAL POSITION SWITCH REMOVAL

GENERAL INFORMATION
The NP242 is a full and part-time transfer case
(Fig. 1). It provides full time 2-wheel, or 4-wheel
drive operation. The NP242 is used in XJ models.
A differential in the transfer case is used to control
torque transfer to the front and rear axles. A low
range gear provides increased low speed torque capa-
bility for off road operation. The low range provides a
2.72:1 reduction ratio.
OPERATING RANGES
NP242 operating ranges are 2WD (2-wheel drive),
4x4 part-time, 4x4 full time, and 4 Lo.
The 2WD and 4x4 full time ranges can be used at
any time and on any road surface.
The 4x4 part-time and 4 Lo ranges are for off road use
only. The only time these ranges can be used on hard sur-
face roads, is when the surface is covered with snow and
ice.
SHIFT MECHANISM
Transfer case operating ranges are selected with a floor
mounted shift lever. The shift lever is connected to the trans-fer case range lever by an adjustable linkage rod. Range po-
sitions are marked on the shift knob or shifter bezel plate.
TRANSFER CASE IDENTIFICATION
A circular I.D. tag is attached to the rear case of
each NP242 transfer case (Fig. 2). The tag provides
the transfer case model number, assembly number,
serial number and low range ratio.
The transfer case serial number also represents the
date of build. For example, a serial number of
1-10-94 would represent January 10, 1994.
RECOMMENDED LUBRICANT/CAPACITY/FILL LEVEL
Mopar Dexron II is the recommended fluid for the
NP242 transfer case. Approximate dry fill lubricant
capacity is 1.4 liters (1.48 qts.).
Correct transfer case lubricant level is to the bot-
tom edge of the fill plug hole.
TRANSFER CASE CHANGES
The only service change for 1995 involves the front
output shaft seal which is new. The new seal does
not have the flange used on prior seals and changes
seal installation. The new seal must be seated below
the edge of the seal bore in the front case. Refer to
the overhaul information for seal installation.

VEHICLE VIBRATION
Vehicle vibration can be caused by:
²Tire/wheel unbalance or excessive runout
²Defective tires with extreme tread wear
²Nylon overlay flat spots (performance tires only)
²Incorrect wheel bearing adjustment (if applicable)
²Loose or worn suspension/steering components
²Certain tire tread patterns
²Incorrect drive shaft angles or excessive drive
shaft/yoke runout
²Defective or worn U-joints
²Excessive brake rotor or drum runout
²Loose engine or transmission supports/mounts
²And by engine operated accessories
Refer to the appropriate Groups in this man-
ual for additional information.
VIBRATION TYPES
There are two types of vehicle vibration:
²Mechanical
²Audible.
Mechanical vehicle vibration can be felt through
the seats, floor pan and/or steering wheel.
Audible vehicle vibration is heard above normal
background noise. The sound can be a droning or
drumming noise.
Vibrations are sensitive to change in engine torque,
vehicle speed or engine speed.
ENGINE TORQUE SENSITIVE VIBRATION
This vibration can be increased or decreased by:
²Accelerating
²Decelerating
²Coasting
²Maintaining a constant vehicle speed
VEHICLE SPEED SENSITIVE VIBRATION
This vibration condition always occurs at the same
vehicle speed regardless of the engine torque or en-
gine speed.
ENGINE SPEED (RPM) SENSITIVE VIBRATION
This vibration occurs at varying engine speeds. It
can be isolated by increasing or decreasing the en-
gine speed with the transmission in NEUTRAL posi-
tion.
VIBRATION DIAGNOSIS
A vibration diagnosis should always begin with a
10 mile (16 km) trip (to warm the vehicle and tires).
Then a road test to identify the vibration. Corrective
action should not be attempted until the vibration
type has been identified via a road test.
During the road test, drive the vehicle on a smooth
surface. If vibration exists, note and record the fol-
lowing information:²Identify the vehicle speed range when the vibra-
tion occurs
²Identify the type of vibration
²Identify the vibration sensitivity
²Determine if the vibration is affected by changes
in vehicle speed, engine speed and engine torque.
When the vibration has been identified, refer to the
Vibration Diagnosis chart for causes. Consider cor-
recting only those causes coded in the chart that are
related to the vibration condition.
Refer to the following cause codes and descriptions
for explanations when referring to the chart.
TRRÐTire and Wheel Radial Runout:Vehicle
speed sensitive, mechanical vibration. The runout
will not cause vibration below 20 mph (32 km/h).
WHÐWheel Hop:Vehicle speed sensitive, me-
chanical vibration. The wheel hop generates rapid
up-down movement in the steering wheel. The vibra-
tion is most noticeable in the 20 - 40 mph (32 - 64
km/h) range. The wheel hop will not cause vibration
below 20 mph (32 km/h). Wheel hop is caused by a
tire/wheel that has a radial runout of more than
0.045 of-an-inch (1.14 mm). If wheel runout is accept-
able and combined runout cannot be reduced by re-
positioning the tire on wheel, replace tire.
TBÐTire/Wheel Balance:Vehicle speed sensitive,
mechanical vibration. Static tire/wheel unbalance
will not cause vibration below 30 mph (46 km/h). Dy-
namic tire/wheel unbalance will not cause vibration
below 40 mph (64 km/h).
TLRÐTire/Wheel Lateral runout:Vehicle speed
sensitive, mechanical vibration. The runout will not
cause vibration below 50 - 55 mph (80 - 88 km/h). Ex-
cessive lateral runout will also cause front-end
shimmy.
TWÐTire Wear:Vehicle speed sensitive, audible
vibration. Abnormal tire wear causes small vibration
in the 30 - 55 mph (88 km/h) range. This will pro-
duce a whine noise at high speed. The whine will
change to a growl noise when the speed is reduced.
WÐTire Waddle:Vehicle speed sensitive, mechan-
ical vibration. Irregular tire uniformity can cause
side-to-side motion during speeds up to 15 mph (24
km/h). If the motion is excessive, identify the defec-
tive tire and replace it.
UAJÐUniversal Joint (Drive Shaft) Angles:
Torque/vehicle speed sensitive, mechanical/audible vi-
bration. Incorrect drive shaft angles cause mechani-
cal vibration below 20 mph (32 km/h) and in the 70
mph (112 km/h) range. The incorrect angles can also
produce an audible vibration in the 20 - 50 mph (32 -
80 km/h) range. Caster adjustment could be required
to correct the angles.
UJÐUniversal Joints:Engine torque/vehicle
speed sensitive, mechanical/audible vibration. If the
