5. Inspect the color of the fluid on the dipstick.
6. A safe operating fluid level is within the HOT crosshatch band on the dipstick. If the fluid level is not within the HOT
band, and the transmission temperature is between 82–93°C (180–200°F), add or drain fluid as necessary to bring
the level into the HOT band. If the fluid level is low, add only enough fluid to bring the level into the HOT band.
NOTE:
To assist in reaching the correct temperature range of 82–93°C (180–200°F), drive the vehicle in second gear
until the desired temperature is reached.
7. If the fluid level is low, add only enough fluid to bring the level into the HOT band. It does not take much fluid,
generally less than one pint (0.5L). Do not overfill. Also, if the fluid level is low, inspect the transmission for leaks.
8. If the fluid level is in the acceptable range, push the dipstick back into the dipstick tube all the way, and then flip the
handle down to lock the dipstick in place.
9. If applicable and if the vehicle is equipped, reset the transmission oil life monitor only if the fluid was changed.
How to Add Fluid
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:
Use only fluid labeled DEXRON® VI, because fluid with that label is made especially for your automatic
transmission. Damage caused by fluid other than DEXRON® VI is not covered by your transmission 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; then flip the handle down to lock the
dipstick in place.
