Automatic Transaxle
Fluid
When to Check
and
Change
A good time to check your automatic
transaxle 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 Chevrolet 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 transaxle. 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
transaxle fluid.
Vait at least 30 minutes before checking
le transaxle fluid level if you have been
riving:
1
When outside temperatures are above
90°F (32°C).
1
At high speed for quite a while.
1
In heavy traffic
--
especially in hot
weather.
1
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).
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), you may
have to drive longer.
To Check the Fluid Level
Park your vehicle on a level place.
With the parking brake applied, place
the shift lever in "P' (Park).
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 "P" (Park).
0
Let the engine run at idle for three to
five minutes.
