Well think what you want then. But the fact is, the 6R80 is the ZF 6HP28. Same trans as used in your mighty BMWs. But you don't think that is the case, so whatever.
You're missing the point man.
It's not the transmission that I have a problem with, it's a very good transmission, it's the lack of the EXTRAS that most cars (especially performance cars) come with, with an automatic transmission.
By "extras" I mean the list in my post above (ie: paddle shifters, sport mode, etc.)
