Car 1: 1989 LS Coupe. iTrader Score: 0 reviews. I agree, parking pawl-if you can move the car more than a couple of inches forward or backwards. Normally, an auto tranny car can rock in both directions before the parking pawl stops it from going further, when it is in park. You might hear a machine gun type of sound if it moves, also-that would be the parking pawl clicking along the teeth of the flywheel.
