level. The fluid level must be in the COLD area,
below the cross-hatched area, for a cold check or in
the HOT area or cross-hatched area for a hot
check.

dipstick back in all the way; then flip the handle

How to Add Fluid

Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Part D:
Recommended Fluids and Lubricants on page 6-33 .
Add fluid only after checking the transmission fluid while
it is 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 one pint
(0.5 L). Don't overfill.
Notice: 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
not covered by your new vehicle warranty.

After adding fluid, recheck the fluid level as
described under "How to Check" earlier.
•
When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.
