OPERATION
The differential assembly is driven by the transfer
shaft by way of the differential ring gear. The ring
gear drives the differential case, and the case drives
the driveshafts through the differential gears. The
differential pinion and side gears are supported in
the case by thrust washers and a pinion shaft. Dif-
ferential pinion and side gears make it possible for
front tires to rotate at different speeds while corner-
ing.
DISASSEMBLY
NOTE: The differential is serviced as an assembly.
Differential service is limited to bearing cups and
cones. Any other differential component failure
must be remedied by differential assembly and
transfer shaft replacement.
The transfer shaft should be removed for differen-
tial repair and bearing turning torque checking.
(1) Remove the differential cover and bolts (Fig.
169) (Fig. 170).
(2) Remove the differential bearing retainer and
bolts (Fig. 171) (Fig. 172).
(3) Using a plastic hammer, remove extension
housing/adapter plate on the right side of the trans-
axle.
WARNING: HOLD ONTO DIFFERENTIAL ASSEMBLY
TO PREVENT IT FROM ROLLING OUT OF HOUSING.
(4) Use Miller Special Tool 5048, 5048-3 Collets,
and L-4539-2 Button to remove the differential bear-
ing cone on the extension housing side.

stick closely. If there is any doubt about its condition,
drain out a sample for a double check.
MopartATF+4 (Automatic Transmission Fluid)
when new is red in color. The ATF is dyed red so it
can be identified from other fluids used in the vehicle
such as engine oil or antifreeze. The red color is not
permanent and is not an indicator of fluid condition.
As the vehicle is driven, the ATF will begin to look
darker in color and may eventually become brown.
This is normal.ATF+4 also has a unique odor that
may change with age. Consequently,odor and color
cannot be used to indicate the fluid condition
or the need for a fluid change.
After the fluid has been checked, seat the dipstick
fully to seal out water and dirt.STANDARD PROCEDURE - FLUID AND FILTER
SERVICE
NOTE: Refer to the maintenance schedules in
LUBRICATION and MAINTENANCE, or the vehicle
owner's manual, for the recommended maintenance
(fluid/filter change) intervals for this transaxle.
NOTE: Only fluids of the type labeled MoparTATF+4
(Automatic Transmission Fluid) should be used. A
filter change should be made at the time of the
transmission oil change. The magnet (on the inside
of the oil pan) should also be cleaned with a clean,
dry cloth.
NOTE: If the transaxle is disassembled for any rea-
son, the fluid and filter should be changed.

FLUID (Continued)

FLUID/FILTER SERVICE (RECOMMENDED)
(1) Raise vehicle on a hoist. Refer to LUBRICA-
TION and MAINTENANCE for proper procedures.
Place a drain container with a large opening, under
transaxle oil pan.
(2) Loosen pan bolts and tap the pan at one corner
to break it loose allowing fluid to drain, then remove
the oil pan.
(3) Install a new filter and o-ring on bottom of the
valve body (Fig. 207).
(4) Clean the oil pan and magnet. Reinstall pan
using new Mopar Silicone Adhesive sealant. Tighten
oil pan bolts to 19 N´m (165 in. lbs.).
(5) Pour four quarts of MopartATF+4 (Automatic
Transmission Fluid) through the dipstick opening.
(6) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.
(7) Check the transaxle fluid level and add an
appropriate amount to bring the transaxle fluid level
to 3mm (1/8 in.) below the lowest mark on the dip-
stick (Fig. 208).
(8) Recheck the fluid level after the transaxle has
reached normal operating temperature (180ÉF.). Refer
to Fluid Level and Condition Check for the proper
fluid fill procedure.
(9) To prevent dirt from entering transaxle, make
certain that dipstick is fully seated into the dipstick
opening.
DIPSTICK TUBE FLUID SUCTION METHOD
(ALTERNATIVE)
(1) When performing the fluid suction method,
make sure the transaxle is at full operating temper-
ature.
(2) To perform the dipstick tube fluid suction
method, use a suitable fluid suction device (VaculaŸ
or equivalent).
(3) Insert the fluid suction line into the dipstick
tube.
NOTE: Verify that the suction line is inserted to the
lowest point of the transaxle oil pan. This will
ensure complete evacuation of the fluid in the pan.
(4) Follow the manufacturers recommended proce-
dure and evacuate the fluid from the transaxle.
(5) Remove the suction line from the dipstick tube.
(6) Pour four quarts of MopartATF+4 (Automatic
Transmission Fluid) through the dipstick opening.
(7) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.
(8) Check the transaxle fluid level and add an
appropriate amount to bring the transaxle fluid level
to 3mm (1/8 in.) below the lowest mark on the dip-
stick (Fig. 208).
(9) Recheck the fluid level after the transaxle has
reached normal operating temperature (180ÉF.).

SOLENOID/PRESSURE
SWITCH ASSY
DESCRIPTION
The Solenoid/Pressure Switch Assembly (Fig. 304)
is external to the transaxle and mounted to thetransaxle case. The assembly consists of four sole-
noids that control hydraulic pressure to the LR/CC,
2/4, OD, and UD friction elements. The reverse
clutch is controlled by line pressure from the manual
valve in the valve body. The solenoids are contained
within the Solenoid/Pressure Switch Assembly, and
can only be serviced by replacing the assembly.
The solenoid assembly also contains pressure
switches that monitor and send hydraulic circuit
information to the PCM/TCM. Likewise, the pressure
switches can only be service by replacing the assem-
bly.
OPERATION
SOLENOIDS
The solenoids receive electrical power from the
Transmission Control Relay through a single wire.
The PCM/TCM energizes or operates the solenoids
individually by grounding the return wire of the sole-
noid needed. When a solenoid is energized, the sole-
noid valve shifts, and a fluid passage is opened or
closed (vented or applied), depending on its default
operating state. The result is an apply or release of a
frictional element.
The 2/4 and UD solenoids are normally applied,
which by design allow fluid to pass through in their
relaxed or ªoffº state. This allows transaxle limp-in
(P,R,N,2) in the event of an electrical failure.
The continuity of the solenoids and circuits are
periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike
