ACCUMULATOR, VALVE BODY, OIL PAN, AND TORQUE CONVERTER
1. Install accumulator inner spring (3) (V-10 engine
only), piston (1), and outer spring (2) (diesel engine
only).
2. Verify that the transmission range sensor hasnot
been installed in case. Valve body can not be
installed if sensor is in position.
3. Install new valve body manual shaft seal (2) in
case. Lubricate seal lip and manual shaft with
petroleum jelly. Start seal over shaft and into case.
Seat seal with 15/16 inch, deep well socket (1).
4. Install valve body as follows:
a. Start park rod into park pawl. If rod will not
slide past park pawl, pawl is engaged in park
gear. Rotate overdrive output shaft with suit-
able size 12 point socket; this will free pawl
and allow rod to engage.
b.Alignandseatvalvebodyoncase.Besure
manual lever shaft and overdrive connector are
fully seated in case.
c. Install and start all valve body attaching bolts
by hand. Then tighten bolts evenly, in a diago-
nal pattern to 12 Nꞏm (105 in. lbs.) torque.Do
not overtighten valve body bolts. This could
result in distortion and cross leakage after
installation..
5. Install new filter on valve body. Tighten filter screws to 4 Nꞏm (35 in. lbs.).
CAUTION: If the condition of the transmission before the overhaul procedure caused excessive metallic or
fiber contamination in the fluid, replace the torque converter. Fluid contamination and transmission failure
can result if not done.
6. Move the transmission manual shaft lever to the manual LOW position.
7. Install the TRS mounting bracket into the transmission case. Using TRS Mounting Bracket Socket 8581 (3),
tighten the mounting bracket (2) to 34 Nꞏm (300 in.lbs.).

d. Push overdrive piston into position in retainer.
e. Verify that the locating lugs entered the lug bores in the retainer.
6. Install intermediate shaft spacer on intermediate shaft.
7. Install overdrive piston thrust plate on overdrive piston.
8. Install overdrive piston thrust bearing on overdrive piston.
9. Install transmission speed sensorand o-ring seal in overdrive case.
INSTALLATION
1. Be sure overdrive unit Alignment Tool 6227-2 is
fully seated before moving unit. If tool is not seated
and gear splines rotate out of alignment, overdrive
unit will have to be disassembled in order to realign
splines.
2. If overdrive piston retainer was not removed during
service and original case gasket is no longer reus-
able, prepare new gasket by trimming it.
3. Cut out old case gasket (1) around piston retainer
with razor knife (2).
4. Use old gasket as template and trim new gasket to
fit.
5. Position new gasket over piston retainer and on
transmission case. Use petroleum jelly to hold gas-
ket in place if necessary. Do not use any type of
sealer to secure gasket. Use petroleum jelly only.
6. Install selective spacer (1) on intermediate shaft
(3), if removed. Spacer goes in groove just rear-
ward of shaft rear splines.
7. Install thrust bearing in overdrive unit sliding hub. Use petroleum jelly to hold bearing in position.
CAUTION: Be sure the shoulder on the inside diameter of the bearing is facingforward.
8. Verify that splines in overdrive planetary gear and overrunning clutchhub are aligned with Alignment Tool 6227-2.
Overdrive unit cannot be installed if splines are not aligned. If splines have rotated out of alignment, unit will
have to be disassembled to realign splines.
9. Carefully slide Alignment Tool 6227-2 out of overdrive planetary gear and overrunning clutch splines.
10. Raise overdrive unit and carefully slide it straight onto intermediate shaft. Insert park rod into park lock reaction
plug at same time. Avoid tilting overdrive during installation as this could cause planetary gear and overrunning
clutch splines to rotate out of alignment. If this occurs, it will be necessary to remove and disassemble overdrive
unit to realign splines.
11. Work overdrive unit forward on intermediate shaft until seated against transmission case.
12. Install bolts attaching overdrive unit to transmission unit. Tightenbolts in diagonal pattern to 34 Nꞏm (25 ft-lbs).
13. Connect the transmission speed sensor and overdrive wiring connectors.
14. Install the transfer case, if equipped. (Refer to 21 - TRANSMISSION/TRANSAXLE/TRANSFER CASE - INSTAL-
LATION)

6– bolt pattern.
Wheels must be replaced if they have:
Excessive runout
Bent or dented
Leak air through welds
Have damaged bolt holes
Wheel repairs employing hammering, heating, or welding are not allowed.
Original equipment wheels are available through your dealer. Replacement wheels from any other source should be
equivalent in:
Load carrying capacity
Diameter
Width
Offset
Mounting configuration
Failure to use equivalent replacement wheels may affect the safety and handling of your vehicle. Replacement with
usedwheels is not recommended. Their service history may have included severetreatment.
DUAL REAR WHEELINSTALLATION
Dual rear wheels use a special heavy duty lug nut wrench. It is recommended to remove and install dual rear
wheels only when the proper wrench is available. The wrench is also use to remove wheel center caps for more
information refer to Owner’s Manual.
The tires on both wheels must be completely raised off the ground when tightening the lug nuts. This will ensure
correct wheel centering and maximum wheel clamping.
A two piece flat face lug nut with right-hand threads is
used for retaining the wheels on the hubs.
The dual rear wheel lug nuts should be tightened
according to the following procedure:
NOTE: Do not use more then two drops of oil on
the nut/washer (1), since the center caps attach in
this area.
Place two drops of oil to the interface of the nut/
washer (1) before installing on the wheel stud.
