Automatic Transmission Fluid - Chevrolet 2007 TrailBlazer Owner's Manua

CAUTION:
{
Operating the engine with the air
cleaner/filter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop flames if
the engine backfires. If it is not there and
the engine backfires, you could be
burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire
can cause a damaging engine fire. And, dirt can
easily get into your engine, which will damage
it. Always have the air cleaner/filter in place
when you are driving.

When to Check and Change Automatic
Transmission Fluid
A good time to check your automatic transmission
fluid level is when the engine oil is changed.
Change the fluid and filter at the intervals listed in
Additional Required Services on page 522, and
be sure to use the transmission fluid listed in
Recommended Fluids and Lubricants on page 529.
How to Check Automatic
Transmission Fluid
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 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.
