Cooling System - Chevrolet 2009 Impala Owner's Manual

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Fluids and Lubricants on page 6-12.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It does not take much fluid, generally less than
one pint (0.5 L). Do not overfill.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 6-12.
3. After adding fluid, recheck the fluid level as
described under "How to Check Automatic
Transmission Fluid," earlier in this section.
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
