When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to check
the transmission fluid level. The only
reason for fluid loss is a
transmission leak or overheating the
transmission. If a small leak is
suspected, use the following
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 dealer and
have it repaired before driving the
vehicle further.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule on page 11 3, and be sure
to use the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11 13.
Vehicle Care
How to Check Automatic
Transmission Fluid
Because this operation can be
difficult, it is recommended to have
this check done at the dealer, which
can monitor the transmission
temperature. The transmission fluid
level increases with temperature. To
obtain a highly accurate fluid level
check, the transmission temperature
must be measured.
If it is decided to check the fluid
level, be sure to follow all the
instructions here, or a false reading
on the dipstick may occur.
Notice: Too much or too little
fluid can damage the
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 checking the
transmission fluid.
