It's not a "circular reference". The thread I linked is the official info from Ford that Administrator @Jarstang posted.:lol:
Circular references don't work.
Where does Ford say that the Performance Package will be available with an automatic?
I think that was speculation on someone's part here and, until it's verifiable, might be getting some folks' hopes up. Nothing I've searched makes reference to this combination other than mustang6g.
Like I said, it's in the "KEY CHANGES".
