question about the bands in an auto trans

Home  \  Domestic Cars  \  question about the bands in an auto trans

I just finished overhauling my 4t60e today. I replaced all the seals, clutches and steels and the molded pistons in everything except the 2nd clutch ( I forgot ). I did not replace the bands because they all still had some kind of a part number printed on them, I assumed the were still ok.
My problem is the trans functions ok when cold but when it gets hot it starts to slip in first. Does this sound like a bad band ? Any help is appreciated.

Did you check adjustment on the bands? It sounds like it could be loose. Of course, there could be an issue with the clutchpack, even though you replaced it.
