Automatic Transmission Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the transmission uid
level. A transmission uid leak is the only
reason for uid loss. If a leak occurs, take the
vehicle to the dealership service department and
have it repaired as soon as possible.
There is a special procedure for checking and
changing the transmission uid. Because
this procedure is difficult, you should have this
done at the dealership service department.Contact your dealer for additional information or
the procedure can be found in the service manual.
To purchase a service manual, seeService
Publications Ordering Information on page 543.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 516.
Change the uid and lter at the intervals listed in
Additional Required Services on page 508, and
be sure to use the uid listed inRecommended
Fluids and Lubricants on page 516.

Maintenance Footnotes
†The U.S. Environmental Protection Agency or
the California Air Resources Board has determined
that the failure to perform this maintenance item
will not nullify the emission warranty or limit
recall liability prior to the completion of the
vehicle’s useful life. We, however, urge that all
recommended maintenance services be performed
at the indicated intervals and the maintenance
be recorded.
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc.

and hoses for proper hook-up, binding, leaks,
cracks, chang, etc.(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.

(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and

you see anything that might keep a safety belt
system from doing its job, have it repaired. Have
any torn or frayed safety belts replaced. Also look
for any opened or broken airbag coverings, and
have them repaired or replaced. The airbag system
does not need regular maintenance.
