I keep getting a 4wd shift in progress message while driving. It mainly happens when I got over bumps in the road. It is more prevalent when I'm towing or when I have my tire pressure set to the factory 60/80. I usually run 50psi all the way around. It seems like there is a micro switch bad or out of adjustment but I can't find one. I also adjusted the linkage to no avail and after doing so figured out it wouldnt matter anyway so I set it back to the original location. Truck is a 2016 2500 tradesman with 30,000 on the odometer. Going to the dealer tomorrow but wanted to post here first....any thoughts?
