Engine Coolant - GMC Chevrolet SSR 2003 Owner's Manual

How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission fluid to use. See
Part D: Recommended Fluids and Lubricants
on page 6-15.
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.
