Chevrolet 2009 Tahoe Automobile User Manual


 
5. Safe operating level is within the HOT cross hatch
band on the dipstick. If the fluid level is not within the
HOT band, and the transmission temperature is
between 160°F and 200°F (71°C and 93°C), 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. It does not
take much fluid, generally less than one pint (0.5L).
Do not overfill.
6. If the fluid level is in the acceptable range, push the
dipstick back in all the way, then flip the handle
down to lock the dipstick in place.
Consistency of Readings
Always check the fluid level at least twice using the
procedure described previously. Consistency (repeatable
readings) is important to maintaining proper fluid level. If
readings are still inconsistent, contact your dealer/retailer.
