In case my sig doesn't show I have 2014 Ram 3500 Laramie Mega Aisin with 74k deleted with DRD MM3 for over a year.
I had just drove 80 miles to drop off my 5th wheel camper to have some items taken care of.
I unhooked, pulled out of the drive and about 1/4 mile down the road, the traction control light came on, check engine light came on, and had messages 4 wheel drive service temp unavailable, and service electronic braking system.
The truck jumped around in gears with the selector letters changing between yellow and white.
I pulled over and shut the truck off for a couple minutes and when I started it, the letters were white but I still had lights on.
The truck drove fine for 40 miles until I stopped for a bite to eat.
I pulled the codes and had U0101.
The truck again drove fine the rest of the way home.
This morning after doing a bunch of research I found that there are common issues with the wiring behind the drivers front wheel well.
I pulled out the cover and check all wiring. Seemed fine.
Started the truck and the gear letters are yellow and I have codes U0101, U0121, and U1412.
I dropped my MM3 box from under the dash to verify all connections to the TCM.
Nothing seems obvious.
Would I create problems by flashing the truck to stock and back?
