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 Chevrolet/Geo 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:
0
When outside temperatures are above
90°F
(32°C).
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).
