How to Check
Because this operation can be a little difficult, you
may choose to have this done at your
GM
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
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). See "Checking Transmission Fluid
Hot" in the Index.
