727 2-3 upshift VERY harsh

Hate to say it Jimmy but it sounds like you got a quickie unless they had 2 or 3 guys working on it. Funny how on the check sheet there's just a check next to the end clearance. I guess that just means it had some. LOL. Would be nice to know what that clearance is. Should be no more than .020 for a performance trans. When you call them tomorrow ask them if they checked it and what it was. Also ask them if they checked the clutch plate clearances and set them to what they should have been. It takes selective snap rings to set the clutch clearance. Also ask them if they shimmed the gear train clearance. It should be no more than .015 on a performance trans. Your correct in thinking backing the kickdown band off too much will affect the 2nd gear shift. Could also cause the band to slip and you probably know what that means. Not good.

If the VB was dirty (that wouldn't surprise me) and he took it apart to clean it maybe he put something back together wrong or left a check ball out. Just another thought.

Let us know how it turns out.
