Hi,

Thank you for asking your question on JustAnswer. Based on your description, it sounds like the Parking brake was set after the truck was put into Park while on an incline, causing the parking prawl to become wedged, you should be able to pop it out. If you need I can send the test procedures in order to determine if the shift lock is bad?

Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.

Hi,

Thank you for asking your question on JustAnswer. The parking pawl prevent the vehicle from rolling away when in the Park position, You can pop it out manually by shifting the shift lever, (which you may have to use a little more force).

As I stated earlier, If you need I can send the test procedures in order to determine if the shift lock is bad?
