the front of the oil
container.

is American Petroleum
Institute certified for. gasoline engines.

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 your Oldsmobile retailer
Service Department.
If yon 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 parts, starting a fire. Be sure to
get an accurate reading if
you check your
transaxle fluid.
Wait at least 30 minutes before, checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
a ' 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.
