Buick 2007 Rainier - Manual (Page 377)

Then, without shutting off the engine, follow
these steps:
1. Flip the handle up and then remove the
dipstick and wipe it with a clean rag or
paper towel.
The automatic
transmission dipstick
handle with this symbol
on it is located in the
engine compartment on
the passenger’s side
of the vehicle.
See Engine Compartment Overview on
page 366 for more information on location.
2. Reinstall it back in all the way, wait three
seconds and then pull it back out again. If
the dipstick does not go down the tube easily,
turn the blade and try again until it is fully
inserted in the tube.
3. Check both sides of the dipstick, and read the
lower level. The fluid level must be in the
COLD area, below the cross-hatched area, for
a cold check or in the HOT or cross-hatched
area for a hot check. Be sure to keep the
dipstick pointed down to get an accurate
reading.
4. If the fluid level is in the acceptable range,
reinstall the dipstick back in all the way;
then flip the handle down to lock the dipstick
in place.
