caprang let me be more specific about what the technician found when I took the truck in he found that there was no tire size at all input in to the TCM, the screen was blank, there was a seperate box on the screen with different size tires to choose from to input into the system but who ever if ever reset the TCM they did not choose the size of my tires and input the info into the TCM, not that it had the wrong size tires in the TCM. I hope this explains my problem better.

 

Gotcha. Sounds like you definitely had a problem so glad to hear its running like a champ again.
