Automatic
Transmission
Fluid
When
to
Check
and
Change
A good time to check your automatic transmission fluid level is when the
engine oil
is
changed. Refer to the Maintenance Schedule to determine
when
to
change your fluid. See “Scheduled Maintenance Services” in the
Index.
How
to
Check
Because this operation
can
be a little difficult, you may choose to have this
done at your
GM
dealer 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 parts or exhaust system parts, starting
a
fire. 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).
0
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 93°C).
