    Mine took a shit with 10K on it. Stumbling in 3rd then banging when it would go in. First dealer would not fix it because it had a PP2 tune in despite Ford Performance calling them and telling them that it is a legit tune.

    Anyone else have this problem?

    First that I have heard about, yeah. That's not really the power level where you start breaking things. I think you got a lemon. Try another dealer?

    The 6R80 failing at NA power level is definitely unusual. What did they diagnose the issue as? Glad they are fixing it for you!

    They hooked a computer to something and Ford told them to replace the assembly.
