THICKNESS / INPUT SHAFT END PLAY: (a) Select the thinnest #4 thrust plate thickness
and install to input clutch assembly (Fig. 139). Use
petrolatum to retain. (b)
Install input clutch assembly into position and
verify that it is completely seated by viewing through
input speed sensor hole. If view through input speed
sensor hole is not as shown in (Fig. 140), the input
clutch assembly is not seated properly.
(c) Remove oil pump o-ring (Fig. 141). Be sure
to reinstall oil pump o-ring after selecting the
proper #4 thrust plate. (d) Install pump and gasket to transmission.
Install and torque bolts. (e) Set up input shaft for measurement with
Indicator Set C3339 and End Play Set 8266 as
shown in (Fig. 142). (f) Measure the input shaft end play with the
transaxle in the vertical position. Input shaft end
play must be within 0.005 to 0.025 inch. For
example, if end play reading is 0.055 inch, select
No. 4 Thrust Plate which is 0.071 to 0.074 thick.
This should provide an input shaft end play read-
ing of 0.020 inch which is within specifications. (g) Refer to the No. 4 thrust plate chart to select

ASSEMBLY
NOTE: The differential is serviced as an assembly.
The only parts that are serviceable within the differ-
ential are the differential bearing cups and cones. If
any other part fails within the differential, you must
replace the differential assembly along with the
transfer shaft.
NOTE: Use MoparTATF RTV (MS-GF41), or equiva-
lent, on retainer and extension housing/adapter
plate to seal to case.
(1) Using Miller Special Tool L-4410, and C-4171,
install differential bearing to differential (extension
housing side) (Fig. 180).
(2) Using Miller Special Tool 5052 and C-4171,
install differential bearing to differential (bearing
retainer side). (3) Using Miller Special Tool 6061 and C-4171,
install differential bearing race to bearing retainer
(Fig. 181). (4) Using Miller Special Tool L±4520 and C-4171,
install differential bearing cup to extension housing. (5) Measure and adjust differential bearing pre-
load (Refer to 21 - TRANSMISSION/TRANSAXLE/
AUTOMATIC - 41TE/FINAL DRIVE -
ADJUSTMENTS) . (6) Install differential assembly to case. Install
extension housing/adapter plate and bearing retainer. (7) Install bearing retainer with a bead of Mopar t
ATF RTV (MS-GF41) and torque bolts (Fig. 182) to
28 N´m (250 in. lbs.).
(8) Install extension housing/adapter plate with a
bead of Mopar tATF RTV (MS-GF41) and torque
bolts to 28 N´m (250 in. lbs.).

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 ²m (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 and 18 inch pounds of bearing
preload. 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 Mopar tSilicone
Rubber Adhesive Sealant. Torque bolts to 28 N ²m
(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. 186). 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. 187). 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.
Fig. 187 Fluid Level Indicator
1 - FLUID LEVEL INDICATOR
21s - 102 40TE AUTOMATIC TRANSAXLERS
FINAL DRIVE (Continued)

(3) Select sensors.
(4) Read the transmission temperature value.
(5) Compare the fluid temperature value with the
fluid temperature chart (Fig. 188). (6) Adjust transmission fluid level shown on the
indicator according to the chart. (7) Check transmission for leaks.
Low fluid level can cause a variety of conditions
because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles
make the fluid spongy, therefore, pressures will be
low and build up slowly. Improper filling can also raise the fluid level too
high. When the transaxle has too much fluid, the
gears churn up foam and cause the same conditions
which occur with a low fluid level. In either case, air bubbles can cause overheating
and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator
operation. Foaming can also result in fluid escaping
from the transaxle vent where it may be mistaken
for a leak.FLUID CONDITION
Along with fluid level, it is important to check the
condition of the fluid. When the fluid smells burned,
and is contaminated with metal or friction material
particles, a complete transaxle recondition is proba-
bly required. Be sure to examine the fluid on the dip-
stick closely. If there is any doubt about its condition,
drain out a sample for a double check. Mopar tATF+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.
