Have you tried using FORScan to check the codes in the modules? The first time I used it on my truck, I discovered a few codes for systems that had never even produced a trouble light.

I have not. The only issue I've had was shudder on acceleration with the wheel turned (2hi). Now I have some whining from the front in 4a with a clunk bang type of grab on accel (then whine goes away). No warning lights here. It does sound like it should be covered in the powertrain warranty. I have to fight my local dealer & report them to factory for my warranty stuff
