AUTOMATIC TRANSMISSION
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 additives. Therefore, do
not add any fluid additives to the transmission. The
only exception to this policy is the use of special
dyes for diagnosing fluid leaks in 6-speed
transmissions. Avoid using transmission sealers as
they may adversely affect seals.
Fluid Level Check — 8-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. An authorized dealer can check your
transmission fluid level using special service tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid Level Check — 6-Speed Transmission
It is best to check the fluid level when the
transmission is at normal operating temperature
(158-176°F / 70-80°C). 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
instrument cluster screen Ú page 89.
Use the following procedure to check the
transmission fluid level properly:

1. Monitor the transmission temperature using the instrument cluster display, and operate
the vehicle as required to reach the normal
operating temperature. If the transmission is
not functioning properly, or the vehicle cannot be driven, see the following Note and Caution
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.
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. 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 Ú page 421. After adding any
quantity of oil through the dipstick tube, wait a
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.

23_DPF_OM_EN_USC_t.book Page 372

SERVICING AND MAINTENANCE373
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. Only
use the COLD region of the dipstick as a rough
reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
8. Reinsert the dipstick. Check for leaks. Release the parking brake.
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 68-86°F / 20-30°C. Only
use the COLD region of the dipstick as a rough
reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
Fluid And Filter Changes — 8-Speed
Transmission
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Fluid And Filter Changes — 6-Speed
Transmission
For the proper maintenance intervals Úpage 344.
In addition, change the fluid and filters if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
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 Ú page 421. 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!
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.
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.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder, and (for 6-speed
transmissions) will require more frequent fluid
and filter changes Ú page 421.

SERVICING AND MAINTENANCE403
WHEEL AND WHEEL TRIM CARE
All wheels and wheel trim, especially aluminum
and chrome plated wheels, should be cleaned
regularly using mild (neutral Ph) soap and water to
maintain their luster and to prevent corrosion.
Wash wheels with the same soap solution
recommended for the body of the vehicle and
remember to always wash when the surfaces are
not hot to the touch.
Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other road
chemicals used to melt ice or control dust on dirt
roads. Use a soft cloth or sponge and mild soap to
wipe away promptly. Do not use harsh chemicals or
a stiff brush. They can damage the wheel’s
protective coating that helps keep them from
corroding and tarnishing. When cleaning extremely dirty wheels including
excessive brake dust, care must be taken in the
selection of tire and wheel cleaning chemicals and
equipment to prevent damage to the wheels.
Mopar® Wheel Treatment or Mopar® Chrome
Cleaner or their equivalent is recommended or
select a non-abrasive, non-acidic cleaner for
aluminum or chrome wheels.
NOTE:If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the
brakes to remove the water droplets from the
brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle
vibration when braking.
Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat Wheels
CAUTION!
Avoid products or automatic car washes that use
acidic solutions or strong alkaline additives or
harsh brushes. Many aftermarket wheel
cleaners and automatic car washes may
damage the wheel's protective finish. Such
damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap, Mopar®
Wheel Cleaner or equivalent is recommended.
CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes or oven cleaner. These
products may damage the wheel's protective
finish. Such damage is not covered by the New
Vehicle Limited Warranty. Only car wash soap,
Mopar® Wheel Cleaner or equivalent is
recommended.CAUTION!
If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners, abrasives,
or polishing compounds. They will permanently
damage this finish and such damage is not
covered by the New Vehicle Limited Warranty.
HAND WASH ONLY USING MILD SOAP AND
WATER WITH A SOFT CLOTH. Used on a regular
basis; this is all that is required to maintain this
finish.
