Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion. This inspection should be made with the vehicle in
a level position.
For 1500 Model axles, the fluid level should be even with
the bottom of the fill hole (within 1/4 in (6.4 mm) of edge
of hole) for the FDU215 HD front axle and C235FE rear
axle.
For all 2500/3500 Model axles, the fluid level should be
1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on
the 9.25 in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on
10.5 in rear axles. The 11.5 in rear axle level should be 1/4
in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole.
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentials
1500 Model rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) MOPAR Limited
Slip Additive be added to the gear lubricant. Refer to
“Fluids, Lubricants, And Genuine Parts” in “Maintaining
7
MAINTAINING YOUR VEHICLE 825

Your Vehicle” for further information. The MOPAR Lim-
ited Slip Additive should be added to the gear lubricant
whenever a fluid change is made to an axle equipped
with a Limited Slip Differential.
2500/3500 Model axlesDO NOT REQUIREany limited
slip oil additive (friction modifiers).
NOTE:When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive), the
Limited Slip Additive should be added before the gear
lubricant is added to insure proper additive fill.
Transfer Case
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in this
section for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid. No chemical flushes should be used
826 MAINTAINING YOUR VEHICLE

in any transmission; only the approved lubricant should
be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, And
Genuine Parts” in this section for fluid specifica-
tions.
Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product and
its performance may be impaired by supplemental addi-
tives. Therefore, do not add any fluid additives to thetransmission. Avoid using transmission sealers as they
may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check — Eight-Speed Transmission
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Routine fluid level checks are not required, therefore the
transmission has no dipstick. Your authorized dealer can
check your transmission fluid level using special service
tools.
If you notice fluid leakage or transmission malfunction,
visit your authorized dealer immediately to have the7

5. Place the shift lever momentarily into each gear posi-
tion (allowing time for the transmission to fully en-
gage in each position), ending with the transmission in
PARK.
6. Remove the dipstick, wipe it clean and reinsert it until
seated.
7. Remove the dipstick again and note the fluid level on
both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid
if the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube
to bring it to the proper level.Do not overfill.Use
ONLY the specified fluid (seeFluids, Lubricants, And
Genuine Partsfor fluid specifications). After adding
any quantity of oil through the dipstick tube, wait aminimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at 60-70°F / 16-21°C. Only use the COLD
region of the dipstick as a rough reference when setting
the fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as required,
once the transmission reaches normal operating tempera-
ture.
CAUTION!
If the fluid temperature is below 50 °F (10 °C) it may
not register on the dipstick. Do not add fluid until
the temperature is elevated enough to produce an
accurate reading. Run the engine at idle, in PARK, to
warm the fluid.

•For tough stains, apply MOPAR Total Clean, or a mild
soap solution to a clean, damp cloth and remove stain.
Use a fresh, damp towel to remove soap residue.
•For grease stains, apply MOPAR Multi-Purpose
Cleaner to a clean, damp cloth and remove stain. Use
a fresh, damp towel to remove soap residue.
•Do not use any harsh solvents or any other form of
protectants on Stain Repel products.
Interior Care
Use MOPAR Total Clean to clean fabric upholstery and
carpeting.
Use MOPAR Total Clean to clean vinyl upholstery.
MOPAR Total Clean is specifically recommended for
leather upholstery.Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPAR Total Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid. Please
do not use polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia-based cleaners to clean your leather
upholstery. Application of a leather conditioner is not
required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.

WARNING!
Do not use silicon-based protection products to clean
your bedliner. Silicon-based products can become
slippery and may result in personal injury.
Spray-On Bedliners are chemically-resistant to many
different types of chemicals (including gasoline, oil,
hydraulic fluids) for short periods of time. If a spill
occurs on your Spray-On Bedliner, rinse the truck out as
soon as possible to avoid permanent damage.
Repairing The Spray-On Bedliner
While extremely tough, it is possible to damage a
Spray-On Bedliner. One common condition is when
loading a heavy pallet and dragging that pallet across the
floor of the bed. If a nail or sharp point is exposed under
the weight of the pallet a scratch or tear is possible. While
not covered by your new vehicle warranty, a cosmetic fixto cover the metal exposed by the scratch is required. To
repair a tear or gouge, follow the directions provided in
the MOPAR Quick Repair Kit.
FUSES
WARNING!
•When replacing a blown fuse, always use an appro-
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Failure
to use proper fuses may result in serious personal
injury, fire and/or property damage.
•Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
