As joecar suggested. "It sounds like a tuning problem." I would start over from scratch and add ltrims and maffreq to your scans.

Make sure that you clear trans adapts after trans work. Sometimes the ecm is trying to compensate for thens issues that do not exist anymore. I have overhauled and replaced many gm tranny's. Mostly 4l60-e on trucks. I get alot of trucks and mostly blazers that once the battery is disconnected for a couple of days the will not idle and stall. It usually takes about a day of driving to clear up. I had a couple of trailblazers that took about two days. Make sure your battery connections are clean and tight. I don't know why it happens or why some do it and others do not but it happens to me about 1 out of 8. My advise before you change things, drive it for a week and see if it relearns.
