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.
Add fluid only after checking the transmission fluid HOT. (A COLD check
is used only as a reference.) If the fluid level is low, add only enough of the
proper fluid to bring the level up to the HOT area for a hot check. It doesn't
take much fluid, generally less than a int. Don't overfill. We recommend
you use only fluid labeled DEXRON
-III,
because fluid with that label is
made especially for your automatic transmission. Damage caused by fluid
other than DEXRON@-111 is not covered by your new vehicle warranty.
