Automatic Transmission Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take the vehicle to the
dealer/retailer service department and have it repaired
as soon as possible.
There is a special procedure for checking and changing
the transmission fluid. Because this procedure is
difficult, you should have this done at the dealer/retailer
service department. Contact your dealer/retailer for
additional information or the procedure can be found in
the service manual. To purchase a service manual,
see Service Publications Ordering Information on
page 7-15.
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 6-11.
Change the fluid and filter at the intervals listed in
Additional Required Services on page 6-5, and be sure
to use the fluid listed in Recommended Fluids and
Lubricants on page 6-11.

How to Check Manual
Transmission Fluid
Because this operation can be difficult, you may choose
to have this done at your dealer/retailer service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
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.
