Chevrolet 2010 Impala Automobile User Manual


 
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then
it is difficult to shift out of P (Park). To prevent torque
lock, set the parking brake and then shift into P (Park).
To find out how, see Shifting Into Park in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Automatic Transmission Shift Lock

unless the ignition is in ON/RUN and the regular
brake pedal is applied.
The shift lock is always functional except in the case of
a an uncharged or low voltage (less than 9 volt) battery.
