3. Check both sides of the dipstick, and read the lower level. The fluid
level must be in the COLD area for a cold check or in the HOT area or
cross-hatched area for a hot check.
4.
If the fluid. level is where it should be, push the dipstick bac\
k in all the
way.
If you have a flip-top handle, flip the handle down to lock it in place.
How To Add Fluid:
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants” in \
the Index.
If the fluid level is low, add only enough of the proper fluid to bring the level
up to the COLD area for a cold check or the HOT area for a hot c\
heck. It
doesn’t take much fluid, generally less than a pint. Don’\
t overfill. We
recommend you use only fluid labeled DEXRON@lIE, because fluids \
with that
label are made especially for your automatic transmission. Damag\
e caused by
fluid other than DEXRON@IIE is not covered by your new vehicle\
warranty.
After adding fluid, recheck the fluid level as described under \
“How To
Check”.
When the correct fluid level is obtained, push the dipstick ba\
ck in all the
way. Flip the handle down
if you have a flip-top handle.

When to Check:
A good time to have it checked is when the engine oil is chang\

How to Check:
Because this operation can be a little difficult, you may choose to have this
done at a
GM dealership Service Department.

Check the fluid level only when your engine is off, the vehic\
le
is parked on
level place and the transmission is cool enough for you to re\
st your fingers
on the transmission case.
Then,
follow these steps: a
