6L80

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?

My 6R80 took a shit at 9k, torque converter broke. @ 620hp/500tq

Got it built, Circle D converter, billet intermediate shaft and Exedy clutches.

Broke again at 37k. Pump and pump housing locked up. @701/540

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.
