Torque Lock - Buick 2000 Park Avenue Owner's Manual

Torque Lock

If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. 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 parking pawl in the transaxle,
so you can pull the shift lever out of PARK (P).

Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brake before you can shift from PARK (P) when the
ignition is in RUN. See "Automatic Transaxle" 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) 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 can't
shift out of PARK (P), try this:
1. Turn the key to the OFF ignition position. Open and
close the driver's door to turn off the retained
accessory power feature.
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 as soon as you can.
