Shifting Out Of Park (P); (Automatic Transmission) - GMC 2005 Canyon Owner's Manual

Torque Lock
If you are parking on a hill and you do not 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) (Automatic Transmission) on page 2-30.
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 parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).

Shifting Out of Park (P)

(Automatic Transmission)

Your vehicle has an automatic transmission shift lock
control system which locks the shift lever in PARK (P)
when the ignition is in the LOCK position. In addition,
you have to fully apply the regular brakes before you
can shift from PARK (P) when the ignition is in ON.
See Automatic Transmission Operation on page 2-21.
If you cannot shift out of PARK (P), ease pressure
on the shift lever by pushing the shift lever all the way
into PARK (P) as you maintain brake application.
Then, move the shift lever into the gear you want.
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Turn the key to ACC. There is no shift interlock in
this key position.
2. Apply and hold the brake until the end of Step 4.
3. Shift the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the gear you want.
5. Have the system fixed as soon as you can.
