528 SERVICING AND MAINTENANCE
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
And Lubricants” in “Technical 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 lubri-
cant should be used. Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis
-
sion Fluid (ATF) is an engineered product and its perfor -
mance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the transmis -
sion. Avoid using transmission sealers as they may
adversely affect seals.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate the brake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids, Lubricants, And Genuine
Parts” in this section for fluid specifications.
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.

SERVICING AND MAINTENANCE 529
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 transmis-
sion 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 And Filter Changes — Eight-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.
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 And Lubricants” in “Technical Specifications” for
further information. This inspection should be made with
the vehicle in a level position.
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, 11.5 in rear axle, and 12.0 in rear axle.
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.
