Yes my Actron scanner won't do live data. I see your point that there are many different things that could be the problem. I am not going back to the shop that rebuilt the trans. They will not be any help. I will take it to a guy my friends say is real honest.
From what I understand the idle switch is used to unlock the converter when you take your foot off the gas. I don't even know that this truck has that deal. That was someone else's suggestion. I would like an easy fix I could do myself but with newer cars that does not happen for me often.
Thanks for all your input. It just helps to talk about this stuff sometimes.
