SERVICING AND MAINTENANCE 227
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.
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 six-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. Your
authorized dealer can check your transmission
fluid level using a special service dipstick. If you
notice fluid leakage or transmission
malfunction, visit your 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
For the proper maintenance intervals
Ú
page 212.
In addition, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if
the transmission is disassembled for any
reason.
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
will require more frequent fluid and filter
changes
Ú
page 270.
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.
