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 — If Equipped
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Useonly 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
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 the
transmission. 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
Check the fluid level when the engine is fully warmed up
and the transmission fluid is at normal operating tem-
perature. Driving with an improper fluid level will
greatly reduce the life of the transmission and of the
fluid. Check the fluid level whenever the vehicle is
serviced.
Fluid Level Check — Procedure
It is best to check the fluid level when the transmission is
at normal operating temperature (170-180°F / 77-82°C for
66RFE transmission, or 158–176°F / 70–80°C for AS66RC
transmission). This normally occurs after at least 15 miles
(25 km) of driving. At normal operating temperature the
fluid cannot be held comfortably between the fingertips.

Chassis
ComponentFluid, Lubricant, or Genuine Part
Automatic Transmission (6.4L Engine with
66RFE Transmission) (For Diesel Engine
See Diesel Supplement) Use only ATF+4 Automatic Transmission Fluid. Failure to use ATF+4
fluid may affect the function or performance of your transmission.
We recommend MOPAR ATF+4 fluid.
Automatic Transmission (6.4L Engine with
AS66RC Transmission) Use only MOPAR ASRC Automatic Transmission Fluid or equivalent.
Failure to use the proper fluid may affect the function or performance
of your transmission.
Transfer Case We recommend you use MOPAR BW44-44 Transfer Case Fluid.
Front and Rear Axle Fluid (4500/5500) We recommend you use GL-5 SAE 75W-90 Synthetic (MS-9763).
Brake Master Cylinder We recommend you use MOPAR DOT 3 and SAE J1703. If DOT 3
brake fluid is not available, then DOT 4 is acceptable.
Power Steering Reservoir We recommend you use MOPAR Power Steering Fluid +4, MOPAR
ATF+4 Automatic Transmission Fluid.

Once A Month Or Before A Long Trip:
•Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic trans-
mission and fill as needed.
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following
pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Rotate the tires. Rotate at the first sign of irregu-
lar wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required.
• Inspect automatic transmission fluid if equipped
with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses
and park brake.
• Inspect engine cooling system protection and
hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or
off-road conditions.
• Lube the front drive shaft fitting. 8
