Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an engi-
neered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmis-
sion. The only exception to this policy is the use
of special dyes for diagnosing fluid leaks. Avoid
using transmission sealers as they may ad-
versely affect seals.
CAUTION!
Do not use chemical flushes in your trans-
mission as the chemicals can damage your
transmission components. Such damage is
not covered by the New Vehicle Limited
Warranty.
Fluid Level Check – 3.6L And 3.0L Diesel
Engine
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 a special service
dipstick.
If you notice fluid leakage or transmission mal-
function, visit your authorized dealer immedi-
ately to have the transmission fluid level
checked. Operating the vehicle with an im-
proper fluid level can cause severe transmis-
sion damage.
CAUTION!
• If a transmission fluid leak occurs, visit
your authorized dealer immediately. Se-
vere transmission damage may occur.
Your authorized dealer has the proper
tools to adjust the fluid level accurately.
Fluid Level Check – 5.7L Engine
It is best to check the fluid level when the
transmission is at normal operating temperature
(approximately 180°F / 82°C). This occurs after
at least 15 miles (25 km) of driving. At normal
operating temperature the fluid cannot be held
comfortably between the fingertips.
Use the following procedure to check the fluid
level properly:
1. Park the vehicle on level ground.
2. Run the engine at idle speed and normal
operating temperature.
3. Fully apply the parking brake, and press the
brake pedal.
4. Place the shift lever momentarily into each
gear position (allowing time for the transmission
to fully engage in each position), ending with the
shift lever in PARK.
5. Remove the dipstick, wipe it clean and rein-
sert it until seated.
