Pontiac 2004 GTO - Manual (Page 212)

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 6-13.
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.
The level should never read over the HOT mark, so be
careful not to add too much. It doesn’t take much
fluid, generally less than 0.6 pints (0.3 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
® -III is
not covered by your new vehicle 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.
Remember to always replace the dipstick and lock
the handle down.
• If fluid has to be added often, there may be a
problem or leak and you should see your vehicle
dealer.
