Torque Lock (Automatic Transmission); Shifting Out Of Park (P) (Automatic Transmission) - GMC 1996 Sonoma Owner's Manual

If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
position, hold the regular brake pedal down. Then, see if
you can move the shift lever away from PARK (P)
without first pulling it toward you. If you can, it means
that the shift lever wasn't fully locked into PARK (P).

Torque Lock (Automatic Transmission)
If you are parking on a hill and you don't shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called "torque lock."
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see "Shifting Into
PARK (P)" in the Index.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the transmission, so you can pull the shift
lever out of PARK
(P).
Shifting Out of PARK (P)
(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock:
You have to fully apply your regular brake before you
can shift from PARK (P) when the ignition is in the
RUN position. See "Automatic Transmission Operation"
in the Index.
If you cannot shift out of PARK (P), ease pressure
on the shift lever
--
push the shift lever all the way
into PARK (P)
a s
you maintain brake application. Then
move the shift lever into the gear you want.
If you ever hold the brake pedal down but still can't
shift out of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed

soon as you can.
