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
check. It doesn't take much fluid, generally less than a pint. Don't overfill.
We recommend you use only fluid labeled DEXRON@-I11 or
DEXRON@-IIE, because fluids with that label are made especially for our
automatic transmission. Damage caused by fluid other than DEXRON -111
or 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 back in all
the way.
