How
to
Check
Because this operation can be a little difficult, you may
choose
to
have this done at the dealership service
department.
If you do it yourself, be sure
to
follow all the instructions
here, or you could get a false reading on the dipstick.
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.
Wait at least 30 minutes before checking the
transmission fluid level
if
you have been driving:
When outside temperatures are above
90°F
(32°C).
At high speed for quite a while.
0
In heavy traffic
-
especially in hot weather.

While pulling
a
trailer.
To
get the right reading, the fluid should be at
normal operating temperature, which is
180°F
to 200°F
(82°C
to
