Did you get your trans back Mark?
I'm going to guess that most likely the torque converter has loosened up a little bit. You will only know if you're having a problem with the transmission if you get a code referring to line pressure.Wondering if Clint diverted some of the torque converter oil flow for higher clutch pressure? Would explain why my Pro Edge converter is acting like a 3000 instead of a 2800 stall.
PS. The ATS trans and Copilot is still working great in my truck.
