Automatic Transmission Fluid
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 527.
Change the fluid and filter at the intervals listed
in the Maintenance Schedule. See Scheduled
Maintenance on page 517. Be sure to use
the transmission fluid listed in Recommended
Fluids and Lubricants on page 527.
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 part 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).
