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.
You can read the transmission sump temperature in the EVIC/DID display (refer to “Electronic Vehicle Informa-
tion Center (EVIC)/Driver Information Display (DID)” in
“Understanding Your Instrument Panel” for further in-
formation).
Use the following procedure to check the transmission
fluid level properly:
1. Monitor the transmission temperature using the
EVIC/DID display, and operate the vehicle as re-
quired to reach the normal operating temperature. If
the transmission is not functioning properly, or the
vehicle cannot be driven, see the NOTE and CAU-
TION below about checking the fluid level at colder
temperatures.
2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60
seconds, and leave the engine running for the rest of
this procedure.598 MAINTAINING YOUR VEHICLE

4. Fully apply the parking brake and press the brake
pedal.
5. Place the gear selector momentarily into each gear
position (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
6. Wipe the area around the dipstick clean to prevent dirt
from entering the transmission.
7. Remove the dipstick, wipe it clean and reinsert it until
seated.
8. 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 (see  Fluids, Lubricants, and
Genuine Parts  for fluid specifications). After adding
any quantity of oil through the dipstick tube, wait a
minimum 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 transmission below
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 for 66RFE transmis-
sion, or 68-86°F / 20-30°C for AS66RC transmission. 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
temperature. 7MAINTAINING YOUR VEHICLE 599

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.
9. Reinsert the dipstick. Check for leaks. Release the
parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated position, as long as its seal remains
engaged in the dipstick tube. Fluid And Filter Changes — Six Speed
Transmission
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter(s) if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and chemicals that are sprayed
on trees and road surfaces during other seasons, are
highly corrosive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne contami-
nants, road surfaces on which the vehicle is operated,600 MAINTAINING YOUR VEHICLE

Chassis
Component Fluid, Lubricant, or Genuine Part
Automatic Transmission (6.4L Engine with 66RFE Trans-
mission) (For Diesel Engine See Diesel Supplement) Use only ATF+4 Automatic Transmission Fluid. Failure
to use ATF+4 fluid may affect the function or perfor-
mance 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. 7MAINTAINING YOUR VEHICLE 629

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.
• 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
