Has anyone Installed a ATS Co Pilot and a Modulated Allison? I installed one on mine and would like to Compare Performance Results.I installed one on a 03 and it worked Excellent. But My 04 is acting a little wierd.It first started out shifting extremly hard and would not ease up even with the co pilot shut off,I took it to gm and had the tech 2 reset the shift trims and it now shifts smoother but still very Erratic,any thoughts? Thanks! Sorry for my Grammer in a Hurry!!
