(5) If the turning torque is within specifications,
remove tools. Setup is complete.
(6) If turning torque is not within specifications
proceed with the following steps.
(a) Remove differential bearing retainer from
the transaxle case.
(b) Remove the bearing cup from the differential
bearing retainer using Tool 6062A.
(c) Remove the existing shim from under the
cup.

PRELOAD ADJUSTMENT W/O SHIM
(1) Remove the bearing cup from the differential
bearing retainer using Miller special Tool 6062A.
(2) Remove existing shim from under bearing cup.
(3) Reinstall the bearing cup into the retainer
using Miller Special Tool 6061, and C-4171.
NOTE: Oil baffle is not required when making the
shim calculation.
(4) Install the bearing retainer into the case.
Torque bolts to 28 N´m (250 in. lbs.).
(5) Position the transaxle assembly vertically on
the support stand and install Miller Special Tool
L-4436-A into the bearing retainer.
(6) Rotate the differential at least one full revolu-
tion to ensure the tapered roller bearings are fully
seated.
(7) Attach a dial indicator to the case and zero the
dial. Place the tip on the end of Special Tool
L-4436-A.
(8) Place a large screwdriver to each side of the
ring gear and lift. Check the dial indicator for the
amount of end play.
CAUTION: Do not damage the transaxle case and/or
differential retainer sealing surface.
(9) Using the end play measurement that was
determined, add 0.18mm (0.007 inch). This should
give you between 5-18 inch pounds of bearing pre-
load. Refer to the Differential Bearing Shim Chart to
determine which shim to use.
(10) Remove the differential bearing retainer.
Remove the bearing cup.
(11) Install the oil baffle. Install the proper shim
combination under the bearing cup.
(12) Install the differential bearing retainer. Seal
the retainer to the housing with MopartSilicone
Rubber Adhesive Sealant. Torque bolts to 28 N´m
(250 in. lbs.).
(13) Using Miller Special Tool L-4436-A and an
inch-pound torque wrench, check the turning torque
of the differential (Fig. 208). The turning torque
should be between 5-18 inch-pounds.
NOTE: If turning torque is too high install a 0.05mm
(0.002 inch) thicker shim. If the turning torque is too
low, install a 0.05mm (0.002 inch) thinner shim.
Repeat until 5-18 inch-pounds of turning torque is
obtained.
FLUID
STANDARD PROCEDURE
FLUID LEVEL AND CONDITION CHECK
NOTE: Only transmission fluid of the type labeled
Mopar ATF+4 (Automatic Transmission Fluid)
should be used in this transaxle.
FLUID LEVEL CHECK
The transmission sump has a fluid level indicator
(dipstick) to check oil similar to most automatic
transmissions. It is located on the left side of the
engine. Be sure to wipe all dirt from dipstick handle
before removing.
The torque converter fills in both the P Park and N
Neutral positions. Place the selector lever in P Park
to be sure that the fluid level check is accurate.The
engine should be running at idle speed for at
least one minute, with the vehicle on level
ground.At normal operating temperature 82É C
(180É F), the fluid level is correct if it is in the HOT
region on the oil level indicator (Fig. 209). The fluid
level should be within the COLD region of the dip-
stick at 27É C (80É F) fluid temperature.
FLUID LEVEL CHECK USING DRB
NOTE: Engine and Transaxle should be at normal
operating temperature before performing this proce-
dure.
(1) Start engine and apply parking brake.
(2) Hook up DRB scan tool and select transmis-
sion.

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 283). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate, the clearance between the gear teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage.
(1) Remove the reaction shaft support bolts.
(2) Remove reaction shaft support from pump
housing (Fig. 284).
(3) Remove the pump gears (Fig. 285) and check
for wear and damage on pump housing and gears.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 286). Clearance should be
0.089±0.202 mm (0.0035-0.0079 in.).
(6) Measure clearance between outer gear and
crescent. Clearance should be 0.060-0.298 mm
(0.0023-0.0117 in.).
(7) Measure clearance between inner gear and
crescent. Clearance should be 0.093-0.385 mm
(0.0036-0.0151 in.).
(8) Position an appropriate piece of Plastigage
across both pump gears.

ASSEMBLY
(1) Assemble oil pump as shown in (Fig. 287)
(2) Install and torque reaction shaft support-to-oil
pump housing bolts to 28 N´m (20 ft. lbs.) torque.
PLANETARY GEARTRAIN
DESCRIPTION
The planetary geartrain is located between the
input clutch assembly and the rear of the transaxle
case. The planetary geartrain consists of two sun
gears, two planetary carriers, two annulus (ring)
gears, and one output shaft (Fig. 288).
OPERATION
The planetary geartrain utilizes two planetary gear
sets that connect the transmission input shaft to the
output shaft. Input and holding clutches drive or lock
different planetary members to change output ratio
or direction.
