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 a
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, starting
a fire. Be sure to get
an accurate reading if you check your transmission fluid.

is in the
acceptable range,
push the dipstick
back in all the
way; then flip
the
handle down to
lock the dipstick
in place.
How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants’’
in the Index.
If the fluid level is low, add only enough
of the proper fluid to bring the
level up to the
COLD area for a cold check or the HOT area for a hot check.
It doesn’t take much fluid, generally
less than a pint. Don’t overfill. We
recommend you use only fluids labeled DEXR0N’-I11 or DEXR0N’-IIE,
because fluids with those labels are made especially for your automatic
transmission. Damage caused by fluids other than DEXRON@-I11 or
DEXRON@-IIE
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
Check.”
When the correct fluid level is obtained, push the dipstick back in all
the way; then flip
the handle down to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid in your manual transmission doesn’t require changing.

NOTICE:
Your radiator cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed to prevent coolant
loss and possible
engine damage from overheating.
Be sure the arrows on the cap

replacement parts. If you don’t, your brakes may no longer work properly.
For example, if someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes can change, for the
worse. The braking performance you’ve come to expect can change in many
other ways if someone puts in the wrong replacement brake parts.
Fluid Leak Check
After the vehicle has been parked for a while, inspect the surface under the
vehicle for water, oil, fuel or other fluids. Water dripping from
the air
conditioning system after it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Battery
Every new vehicle has a Delco Freedom@ battery. You never have to add
water
to one of these. When it’s time for a new battery, we recommend a
Delco Freedom@ battery. Get one that has the catalog number shown on the
original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.
Contact your dealer to learn how to prepare your vehicle for longer storage
periods.

Refer to the Maintenance Schedule to determine how often the slip and
universal joints must be lubricated and what type of lubricant to use.
Body
Normal use of your vehicle will cause metal to metal wear at some points on
the cab and body if they are not lubricated.
For exposed surfaces, such as door checks, door lock bolts, lock s\
triker plates,
dovetail bumper wedges, etc., a
thin film of engine oil should be applied.
Where oil holes are provided
in the body or cab, a dripless oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
Door weatherstrips and rubber hood bumpers should be wiped clean with a
wet cloth and lightly coated with a rubber lubricant.
Never use too much of any lubricant and be sure to wipe up any extra
lubricant when
you are finished.
Window regulators and controls are inside the doors. They are lubricated
with a long lasting grease.
If lubrication is required your dealer should
perform this service.
Refer to the Maintenance Schedule to determine how often to lubricate
these items and what type of lubricant to use.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer to the Maintenance Schedule to determine how often
to lubricate them
and what type of lubricant to
use.
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause
the lock to bind. De-icers which contain
alcohol could also wash away the lubricant,
so be sure to lubricate the lock
after using a de-icer of this type.
Endgate Handle
The endgate handle pivot points on your vehicle should be lubricated to
keep the handle working smoothly.
Refer to the Maintenance Schedule
to determine how often to lubricate them
and what type of lubricant to use.

air-fuel mixture at a proper level. Use only unleaded fuel
in your vehicle. If
you use leaded fuel, you could damage your oxygen (02) sensor and affect
your vehicle’s emissions.

If it does not come on
when you start your engine, or
if it comes on and stays on while you’re
driving, your system may need service. Your vehicle should still be
driveable, but you should have your system serviced right away.
