ADJUSTMENTS
ADJUSTMENT - DIFFERENTIAL TURNING
TORQUE
NOTE: Differential turning torque should only be
measured with the geartrain out of the transaxle. If
measurement is taken with transaxle assembled, an
inaccurate measurement will result.
NOTE: All differential cover-to-case bolts and exten-
sion housing-to-case bolts must be installed and
torqued to obtain accurate measurement.(1) If transaxle is assembled, remove geartrain
and leave differential in place. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/MANUAL - DISASSEMBLY)
(2) Install differential cover and torque differential
cover-to-case bolts to 54 N´m (40 ft. lbs.).
(3) Install extension housing and torque extension
housing-to-case bolts to 28 N´m (250 in. lbs.).
(4) Place transaxle on work bench so axle center-
line is parallel to the ground.
(5) Install turning torque tool C-4995 to differen-
tial at side opposite extension housing.
(6) Using in. lb./N´m dial indicator, rotate differen-
tial case multiple times and record measurement
(Fig. 123). Differential turning torque should be
within 2.3-3.4 N´m (20-30 in. lbs.). Refer to shim
chart for proper shim selection. If turning torque
measured is less than 2.3 N´m (20 in. lbs.), install a
thicker shim. If turning torque measured is greater
than 3.4 N´m (30 in. lbs.), install a thinner shim.

ADJUSTMENT - DIFFERENTIAL SIDE GEAR
END PLAY
Measure side gear end play: Insert feeler gauges
180É apart between differential side gear and thrust
washer as shown in (Fig. 124). Measurement taken
here applies to both sides. Side gear end play should
be between 0.025-0.152 mm (0.001-0.006 in.). If clear-ance is greater than 0.152 mm (0.006 in.), install a
thicker thrust washer (both sides). If clearance is less
than 0.025 mm (0.001), install a thinner thrust
washer (both sides). Refer to (Fig. 125) for available
side gear shim thicknesses.

If end play measurement indicates a thrust washer
change is necessary, the differential must be disas-
sembled. (Refer to 21 - TRANSMISSION/TRANS-

STANDARD PROCEDURE - FLUID LEVEL
CHECK
NOTE: For proper fluid level check intervals, (Refer
to LUBRICATION & MAINTENANCE/MAINTENANCE

The fluid required in this transaxle is Mopart
ATF+4. Use of substitute fluids may result in
improper transaxle operation and/or failure.
(1) Raise vehicle on hoist.
(2) Remove transaxle fill plug (Fig. 126).
(3) Inspect fluid level. Fluid should be within 3/16º
below fill hole. Add MopartATF+4 as neccessary.
(4) Install fill plug, ensuring it is properly seated.
(5) Lower vehicle.

INTERMEDIATE SHAFT
DESCRIPTION
The intermediate shaft assembly (Fig. 227) is part
of the transaxle geartrain, meshes with and is driven
by the input shaft, drives the differential via an inte-
grated pinion gear, and consists of the following com-
ponents:
²Intermediate Mainshaft
²1st Speed Gear
²2nd Speed Gear
²3/4 Cluster Gear
²5th Speed Gear
²Reverse Gear
²1/2 Synchronizer
²5/R Synchronizer
The intermediate shaft is supported by a caged
roller bearing at the front of the transaxle, and a
sealed roller bearing at the rear of the transaxle.DISASSEMBLY
CAUTION: Do not re-use snap rings when servicing
the intermediate shaft assembly. Discard upon dis-
assembly and install new ones provided with avail-
able snap ring service kit.
NOTE: Depending on date of transaxle manufacture,
some intermediate shafts will utilize a needle bear-
ing under the 2nd and 5th Speed Gears.
(1) Install intermediate shaft assembly to arbor
press table with bearing splitter P-334 under the
reverse gear.
