SERVICE SLEEVE ASSEMBLY
NOTE: Two sleeve halves are included with each
kit. Modifications as follow, are necessary to create
the correct sleeve assembly for each application.
(1) On 4X2 models, the9lower9sleeve is made by
cutting off the tab and cutting out a notch in the bot-
tom sleeve portion. Round the corners of the cut out
to keep stress cracks from forming. On 4X4 models
the9lower9sleeve is used as provided. (Fig. 15)
(2) On both 4X2 and 4X4 models cut off the front
tab on the upper sleeve portion. (Fig. 16)(3) The sleeve halves are shipped slightly over-
sized to allow custom fitting to each replacement
frame rail tip. It is necessary to grind the mating
surfaces to achieve the desired snug fit into the
replacement tip (rail tube has increasing height rear-
ward of the cut line). Once the two sleeve halves are
fitted, bevel the edges 25É - 30É.
NOTE: Scribing a line 2 mm from the cut edge and
then grinding back to the mark will simplify the
bevel creation process and accuracy.
(4) Remove any burrs at the beveled edges.
(5) Using the Weld Process Specifications table
(Refer to 13 - FRAME & BUMPERS/FRAME - SPEC-
IFICATIONS - WELDING), weld the two halves of
the repair sleeve together. (Fig. 17)
(6) Clean the welds of any flux and other impuri-
ties and grind smooth before proceeding with the
installation of the sleeve.
(7) Find the centerline of the sleeve and scribe a
centerline mark. Mark two additional lines 2 mm
(0.08 in.) on either side of the centerline mark to help
ensure the required 4 mm-6mm(0.16 in. - 0.24 in.)
weld root gap. (Fig. 17)

STANDARD PROCEDURE - REAR FRAME
H-SECTION REPLACEMENT
CAUTION: This procedure is designed to replace
the H-section/spare tire support located at the rear
of the frame assembly. Prior to any cutting, the
vehicle must be mounted on the appropriate frame
repair equipment (ªframe rackº), checked with three
dimensional measuring equipment, and the neces-
sary pull corrections made. If damage remains in
the frame beyond the area covered by this service
part after the pull, the frame must be replaced in its
entirety.

DIAGNOSIS AND TESTING - CONVERTER
HOUSING FLUID LEAK
When diagnosing converter housing fluid leaks,
two items must be established before repair.
(1) Verify that a leak condition actually exists.
(2) Determined the true source of the leak.
Some suspected converter housing fluid leaks may
not be leaks at all. They may only be the result of
residual fluid in the converter housing, or excess
fluid spilled during factory fill or fill after repair.
Converter housing leaks have several potential
sources. Through careful observation, a leak source
can be identified before removing the transmission
for repair. Torque converter seal leaks tend to move
along the drive hub and onto the rear of the con-
verter. Pump cover seal tend to run down the cover
and the inside surface of the bellhousing.
Some leaks, or suspected leaks, may be particu-
larly difficult to locate. If necessary, a Mopart
approved dye may be used to locate a leak.
TORQUE CONVERTER LEAK POINTS
Possible sources of converter leaks are:
(1) Leaks at the weld joint around the outside
diameter weld (Fig. 7).
(2) Leaks at the converter hub weld (Fig. 7).
STANDARD PROCEDURE - ALUMINUM
THREAD REPAIR
Damaged or worn threads in the aluminum trans-
mission case and valve body can be repaired by the
use of Heli-CoilsŸ, or equivalent. This repair con-
sists of drilling out the worn-out damaged threads.
Then tap the hole with a special Heli-CoilŸ tap, or
equivalent, and installing a Heli-CoilŸ insert, or
equivalent, into the hole. This brings the hole back to
its original thread size.
Heli-CoilŸ, or equivalent, tools and inserts are
readily available from most automotive parts suppli-
ers.
REMOVAL
(1) Disconnect the negative battery cable.
(2) Raise and support the vehicle
(3) Remove any necessary skid plates. (Refer to 13
- FRAMES & BUMPERS/FRAME/TRANSFER CASE
SKID PLATE - REMOVAL)
(4) Mark propeller shaft and axle companion
flanges for assembly alignment.
(5) Remove the rear propeller shaft
(6) Remove the front propeller shaft, if necessary.
(7) Remove the engine to transmission collar (Fig.
8).
(8) Remove the exhaust support bracket from the
rear of the transmission.
(9) Disconnect and lower or remove any necessary
exhaust components.
