When to Add Oil
If the oil is at or below the ADD mark you’ll need to
add some oil.
But you must use the right kind. This part
explains what kind of oil to use.
For crankcase capacity,
see “Capacities and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.

Then install the longer knobs into the outer holes.
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 your Chevrolet 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.

I 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.

Downloaded from www.Manualslib.com manuals search engine 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).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
To get the right reading, the fluid should be at normal
operating temperature, which is
1 80°F to 200°F (82 "C
to 93 " C).
To check transmission fluid hot: Get the vehicle
warmed up by driving about
15 miles (24 km) when
outside temperatures are above 50°F
(10°C). You may
have to drive longer to bring the fluid to 180°F to
200" F
(82°C to 93 "C) in colder outside temperatures. See
"Automatic Transmission Fluid Temperature Reading"
in the Index.
To check transmission fluid cold: A cold check is
made after the vehicle has been sitting for eight hours or
more with the engine off and is used only as a reference.
Let the engine run at idle for five minutes if outside
temperatures are
50°F (10°C) or more. If it's colder
than
50°F (IOOC), you may have to idle the engine
longer. Should the fluid level be low during a cold
check, you
must perform a hot check before adding
fluid. This will give you
a more accurate reading of the
fluid level.
To check the fluid hot or cold

With the parking brake applied, place the shift lever
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in PARK (P).
Let the engine run at idle for three minutes or more.
Then, without shutting off the engine, follow these steps:
1. Pull out the dipstick and wipe it with a clean rag or
paper towel.

then pull it back out again.

Check both sides of the dipstick, and read the lower
level. The fluid level should be in the area marked
“80°F” for a cold check and will move into the
“WARM”
area as the temperature increases. When
the fluid is at normal operating temperature
( 180 OF
to 200”F, 82°C to 93”C), the level must be in the
crosshatched area marked
“1 90°F.” See “Automatic
Transmission Fluid Temperature Reading” in the
Index.
If the fluid level is in the acceptable range, push the
dipstick back in all the way.
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.
Add fluid only after checking the transmission fluid
HOT.
(A COLD check is used only as a reference.) If
the fluid level is low, add only enough of the proper
fluid to bring the level up to the HOT area for a hot
check. It doesn’t take much fluid, generally less than a
pint.
Don ’t ove@ZZ. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON@-I11 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”

1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of
the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated.
If the fluid level is low, add more
fluid as described in the next steps.

Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level up to the bottom
of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The clutch linkage in your vehicle is self-adjusting. The
clutch master cylinder reservoir is filled with hydraulic
clutch fluid.
It isn’t a good idea to “top
off’ your clutch fluid. Adding
fluid won’t correct a leak.
A fluid
loss in this system could indicate a problem.
Have
the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the fluid level in
your clutch
master cylinder reservoir and for the proper fluid. See
“Owner Checks and Services” and “Recommended
Fluids and Lubricants” in the Index.

Loosen the two inboard nuts on the unit. Move the ECM
unit to either side.
Fluid should be added if the fluid level is at or below the
ADD mark on the reservoir. There are additional
instructions on the reservoir cap.
When returning the
ECM to its proper position, make
sure the bolts are aligned with the slots in the bracket.
Then gently push down on the unit. When replacing the
unit, be careful not to over-tighten the nuts --just
tighten them until they are snug.
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. See “Periodic Maintenance
Inspections” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler
plug hole.
