When to Check and Change Automatic
Transmission Fluid
It is usually not necessary to check the
transmission fluid level. A transmission fluid leak is
the only reason for fluid loss. If you suspect a
small leak, then use the following checking
procedures to check the fluid level. However, if
there is a large leak, then it may be necessary to
have the vehicle towed to a dealership service
department and have it repaired before driving the
vehicle further.
Notice: Use of the incorrect automatic
transmission fluid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission fluid listed in Recommended
Fluids and Lubricants on page 533.
Change the fluid and filter at the intervals listed in
the Maintenance Schedule. See Scheduled
Maintenance on page 523. Be sure to use the
transmission fluid listed in Recommended Fluids
and Lubricants on page 533.
How to Check Automatic
Transmission Fluid
Notice: Too much or too little fluid can
damage your transmission. Too much can
mean that some of the fluid could come out
and fall on hot engine parts or exhaust system
parts, starting a fire. Too little fluid could
cause the transmission to overheat. Be sure to
get an accurate reading if you check your
transmission fluid.
Before checking the fluid level, prepare your
vehicle as follows:
1. Start the engine and park your vehicle on a
level surface. Keep the engine running.
2. Apply the parking brake and place the shift
lever in PARK (P).
3. With your foot on the brake pedal, move the
shift lever through each gear range, pausing
for about three seconds in each range.
Then, move the shift lever back to PARK (P).
4. Allow the engine to idle (500 – 800 rpm) for at
least one minute. Slowly release the brake
pedal.
