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 supple-
mental 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. Avoid using
transmission sealers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check — Four-Speed Automatic
Transmission
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Run the engine at normal idle speed for at least 60
seconds, and leave the engine running for the rest of this
procedure.
3. Fully apply the parking brake, and press the brake
pedal.
4. 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.
5. Wipe the area around the dipstick clean to prevent dirt
from entering the transmission.
6. Remove the dipstick and determine if the fluid is hot or
cold. You can also read the transmission fluid tempera-
ture using the instrument cluster. Refer to ⬙Instrument
Cluster Display⬙ in ⬙Understanding Your Instrument
Panel⬙ for further information. Hot fluid is approxi-
mately 180°F (82°C), which is the normal operating
temperature after the vehicle is driven at least 15 miles
(24 km). Hot fluid cannot be held comfortably between
the fingertips. Cold fluid is at a temperature of approxi-
mately 80°F (27°C).
