Thanks, I'll have to look into it. I'm hoping they get a programer soon for these new engines, that will block codes on EGR and cat. And put a little more power out. Then I guess the transgo would be a good thing to do. I don't know if anyone has the data on whatn this new trans safely hold. I never did anything to the trans on the 02 except transynd and deep pan. Ran juice 90 hp box on level 2 towing and 3 or 4 running empty. Ran it pretty hard and never had a slip or limp or code had 65,000 miles when we traded.
