THE SAME THING HAPPENS TO ME WHEN I PARK THE TRUCK UPHILL ON MY DRIVEWAY. WHAT I DO IS HAVE SOME ONE PUSH THE TRUCK FORWARD A LITTLE SO IT UNLOCKS THE TRANSMISSION. MAKE SURE BEFORE YOU PUT THE TRUCK INTO PARK TO PUT THE EMERGENCY BRAKE THEN PUT IT INTO PARK AND TURN OFF THE ENGINE. REVERSE THE PROCEDURE WHEN STARTING. START ENGINE PRESS ON BRAKE TAKE IT OUT OF PARK AND LAST REALESE THE EMERGENCY BRAKE.

try to adjust the neutral park switch.
