be sure to drain all free-flowing
oil from the filter before disposal. Don’t
ever dispose
of oil by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies
of water. Instead, recycle it by taking it to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station
or a local recycling center
for help.

still attached after the filter is changed.
Refer to the Maintenance Schedule to determine when to replace the air
filter.
See “Scheduled Maintenance Services”
in the Index.

it. Always have the air cleaner in place when you’re driving.
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 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.
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).
0 At high speed for quite a while.
0 In heavy traffic - especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is 180°F to
200°F (82°C to 93°C).
6- 18

Downloaded from www.Manualslib.com manuals search engine 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).
If it's colder than
50°F (lO°C), drive the vehicle in DRIVE (D) until the
engine temperature gage moves and then remains steady for ten minutes.
Then follow the hot check procedures.
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 (lO"C), 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
Park your vehicle on a level place. Keep the engine running.
With the parking brake applied, place the shift lever in PARK (P).
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. Flip the handle up and then pull out the dipstick and wipe it with a

level must be in the COLD area for a cold check or in the
HOT area or
cross-hatched area for a hot check.
4. If the fluid level 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.
Add fluid only after checking the transmission fluid

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 int.
Don ’t overjill. We recommend
you use only fluid labeled DEXRON
8 -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.”
