GMC 2007 Envoy - Manual (Page 403)

Checking the Fluid Level
Prepare your vehicle as follows:
1. Park your vehicle on a level place. Keep the
engine running.
2. With the parking brake applied, place the shift
lever in PARK (P).
3. With your foot on the brake pedal, move the
shift lever through each gear range, pausing
for about three seconds in each range.
Then, position the shift lever in PARK (P).
4. Let the engine run at idle for three minutes
or more.
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 390 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.
