A utomafic 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
t o
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.
