GMC Terrain: Torque Lock - Shifting Into Park - Starting and Operating - Driving and Operating - GMC Terrain Owner's ManualGMC Terrain: 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” listed previously.
