236SERVICING AND MAINTENANCE
AUTOMATIC TRANSMISSION
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use the manufacturer specified transmission
fluid Úpage 274. It is important to maintain the
transmission fluid at the correct level using the
recommended fluid.
NOTE:
No chemical flushes should be used in any trans -
mission; only the approved lubricant should be used.

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 9-speed
transmissions. Avoid using transmission sealers as
they may adversely affect seals.
Fluid Level Check

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 filler tube is capped and no dipstick
is provided. An authorized dealer can check your
transmission fluid level using a special service dipstick.
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
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.
FUSES
General Information
The fuses protect electrical systems against
excessive current.

When a device does not work, you must check the fuse
element inside the blade fuse for a break/melt.

CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú
page 274.
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.
