After much fiddling around with my dash, I think I may have resolved this problem that’s been bugging me ever since I bought the truck. The shift indicator (PRND21) on the dash would stay on either Drive, 2, or 1, and would not return to the Park, Reverse or Neutral settings. Had to take apart most of the dashboard to get to it, but after lubricating, and running it back-and-forth, I think I may have resolved the problem for the most part...it's been working now for a few months after the lube-job.
Hope this helps you out too! For more videos like this, check out KevinsOffroad.com/blog
