SERVICING AND MAINTENANCE 233
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” for fluid specifications. 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
tr
ansmission; 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.
Th
erefore, 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.
Fluid Level Check
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
l
east 60 seconds, and leave the engine
running for the rest of this procedure.
3. Fully apply the parking brake, and press the
b
rake pedal.
4. Place the gear selector momentarily into
e
ach 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
p
revent dirt from entering the transmission.
6. Remove the dipstick and determine if the
f
luid is hot or cold. You can also read the
transmission fluid temperature using the
instrument cluster. Refer to "Instrument
Cluster Display" in "Getting To Know Your
Instrument Panel" for further information.
Hot fluid is approximately 180°F (82°C),
which is the normal operating temperature
after the vehicle is driven at least 15
miles
(2
4 km). Hot fluid cannot be held
co
mfortably between the fingertips. Cold
fluid is at a temperature of approximately
80°F (27°C).
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. Refer to
“Fluids And Lubricants” in “Technical
Specifications” 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.
