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 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.
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.
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.
0 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).
To check transmission fluid hot: Get the vehicle warmed up by driving
about
15 miles (24 krn) when outside temperatures are above 50°F ( 1 0°C).
If it’s colder than 50°F (lO”C), drive the vehicle in THIRD GEAR (D) until
the engine temperature gage moves and then remains steady for ten minutes.
Then follow the hot check procedures.

The headlamp wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights to go on and
off, or in some cases to
remain off. If this happens, have your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due to heavy snow, etc., the wiper will stop until the
motor cools. If the overload is caused by some electrical problem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the problem is fixed.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse is near the junction block in the
front, driver’s side fender. See “Trailer Wiring Harness”
in the Features &
Controls section.
Fuse Block
. .. . .,
The fuse block is in
the instrument panel
on the driver’s side.
Remove the cover by
turning the fastener
counterclockwise.
Then you can remove
fuses with a fuse
extractor. Extra fuses
are provided in the
cover.
