Chevrolet 1998 Cavalier Owner's Manual page 280

If you do nor use your vehicle under any of these
conditions, the fluid and filter do not require changing.
NOTICE:
We recommend you use only fluid labeled
DEXR0N'-111, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON-I11
is not covered by your new vehicle warranty.
Manual Transaxle Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transaxle
doesn't require changing.
How to Check
Because this operation can be a little difficult, you
may
choose to have this done at your 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.
ITICE:
Too much or too little fluid can damage your
manual transaxle. Too much can mean that some
of the fluid could come out and fall on hot engine
1
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transaxle fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the manual
transaxle is cool enough for you to rest your fingers on
the transaxle case.
