VALVE-TORQUE CONVERTER DRAINBACK
DESCRIPTION
GAS ENGINES
The drainback valve is located in the transmission cooler outlet (pressure) line.
DIESEL ENGINE
The converter drainback check valve is located in the in the TOC pressure - supply line, between the engine
mounted TOC and the air to oil TOC.
OPERATION
GAS ENGINES
The valve prevents fluid from draining from the converter into the cooler and lines when the vehicle is shut down for
lengthy periods. Production valves have a hose nipple at one end, while theopposite end is threaded for a flare
fitting. All valves have an arrow (or similar mark) to indicate direction of flow through the valve.
DIESEL ENGINE
The valve prevents fluid from draining from the converter into the cooler and lines when the vehicle is shut down for
lengthy periods. Production valves have pipe thread on one end, while the opposite end is threaded for a flare
fitting, and are threaded into the oil cooler mounted on the side of the engine. All valves have an arrow (or similar
mark) to indicate direction of flow through the valve.
STANDARD PROCEDURE
GAS ENGINES
The converter drainback check valve is located in the cooler outlet (pressure) line near the radiator tank. The valve
prevents fluid drainback when the vehicle is parked for lengthy periods. The valve check ball is spring loaded and
has an opening pressure of approximately 2 psi.
The valve is serviced as an assembly; it is not repairable. Do not clean the valve if restricted, or contaminated by
sludge, or debris. If the valve fails, or if a transmission malfunction occurs that generates significant amounts of
sludge and/or clutch particles and metal shavings, the valve must be replaced.
If the valve is restricted, installed backwards, or in the wrong line, it will cause an transmission overheating condition
and possible transmission failure.
CAUTION: The drainback valve is a one-way flow device. It must be properly orientedintermsofflowdirec-
tion for the cooler to function properly. The valve must be installed in thepressure line. Otherwise flow will
be blocked and would cause an transmission overheating condition and eventual transmission failure.

WHEEL DESIGN
The rim size is on the vehicle safety certification label
located on the drivers door shut face. The size of the
rim is determined by the drivetrain package. Original
equipment wheels/rims are designed for operation up
to the specified maximum vehicle capacity.
All models use stamped steel, cast aluminum or
forged aluminum wheels. Every wheel has raised sec-
tions between the rim flanges (1) and rim drop well (3)
called safety humps.
Initial inflation of the tire forces the bead over these
raised sections. In case of rapid loss of air pressure,
the raised sections help hold the tire on the wheel.
The wheel studs and nuts are designed for specific
applications. All aluminum and some steel wheels
have wheel stud nuts with an enlarged nose. This
enlarged nose is necessary to ensure proper retention
of the wheels. Do not use replacement studs or nuts with a different design orlesserquality.
DIAGNOSIS AND TESTING
WHEEL INSPECTION
Inspect wheels for:
Excessive run out
Dents or cracks
Damaged wheel lug nut holes
Air Leaks from any area or surface of the rim
NOTE: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged an original equipment replacement wheel should be used. When obtaining replacement
wheels, they should be equivalent in load carrying capacity. The diameter, width, offset, pilot hole and bolt circle of
the wheel should be the same as the original wheel.
WARNING: Failure to use equivalent replacement wheels may adversely affect the safety and handling of
the vehicle. Used wheels are not recommended. The service history of the wheel may have included severe
treatment or very high mileage. The rim could fail without warning.
STANDARD PROCEDURE
WHEEL REPLACEMENT
The wheel studs and nuts are designed for specific applications. They mustbe replaced with equivalent parts. Do
not use replacement parts of lesser quality or a substitute design. All aluminum and some steel wheels have wheel
stud nuts which feature an enlarged nose. This enlarged nose is necessary to ensure proper retention of the alu-
minum wheels.
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.

PANEL SECTIONING
If it is required to section a large panel for a plastic
repair, it will be necessary to reinforce the panel. To
bond two plastic panels together, a reinforcement
must overlap both panels. The panels must be “V’d” at
a 20 degree angle. The area to be reinforced should
be washed, then sanded. Be sure to wipe off any
excess soap and water when finished. Lightly sand or
abrade the plastic with an abrasive pad or sandpaper.
Blow off any dust with compressed air or wipe with a
clean dry rag.
When bonding plastic panels, follow repair material
manufacturers recommendations. Be sure that enough
adhesive has been applied to allow squeeze out and
to fill the full bond line. Once the pieces have been
brought together, do not move them until the adhesive
is cured. The assembly can be held together with
clamps, rivets, etc. A faster cure can be obtained by heating with a heat lamp or heat gun. After the parts have been
bonded and have had time to cure, rough sand the seam and apply the final adhesive filler to the area being
repaired. Smooth the filler with a spreader, wooden tongue depressor, or squeegee. For fine texturing, a small
amount of water can be applied to the filler surface while smoothing. The cured filler can be sanded as necessary
and, as a final step, cleanup can be done with soapy water. Wipe the surface clean with a dry cloth allowing time
for the panel to dry before moving on with the repair.
