Thanks!!! https://www.gm-trucks.com/forums/profile/255553-jeremiah-martin/ I have a few months looking to solve this problem yesterday it got real bad wouldn't stop at all from the shift to park message. So did what you mentioned removed the 3 7mm screws removed the bottom cover and jumped the micro switch with a small fuse, boom!!!! Fixed. Looking for the replacement part but so far so good thanks again!!!
