Sounds like a repeat of the T-45 fiasco, which Ford never acknowledged or addressed (as far as I recall).
It's understandable that some suppliers might provide shoddy parts outside of Ford's control. The only acceptable move for Ford is to aggressively and promptly solve the problem. We'll see.

That is correct. Ford does not officially publish this spec nor does Getrag. The only reason why this spec is known is because the Ford engine designers had to design the Coyote's torque to that spec. They revealed this in an interview.
If you look at the Coyote's torque curve, you will see that it only hits 390 ft-lbf crank very very briefly.
And notice that the Roadrunner Boss had it's torque cut down to 380.
The Coyote and Roadrunner are capable of so much more, I bet they can reliably pump out 425/425 BHP/ft-lbf crank (same as the Camaro 6.2L Ss engine). But the MT82 is one of the limiting factors, and not necessarily CAFE.

edit: I just read on another site that the MT-82 is the same transmission as the 6MTI500 that is listed on their website and rated at 369 lb/ft torque.

Read up on NHTSA mandatory recalls, there is rarely any comprimise.
If this were true there would be a higher rate of failure amongst people that are adding power, it doesn't appear to be that way.
It is great they are investigating it, but people need to calm down. I am betting there is less than a 5% failure rate (likely it is probably around 1%). Unfortunately, if you do an internet survey it is going to appear a lot larger. Most people find forums to post on when they have problem, otherwise they would never be here.
Apr 10 build 11 v6 here, almost 20k miles and not a hint of an issue.

"Although none of the 32 complaints received by the NHTSA included any accidents or injuries - there is an obvious increased danger to the driver and others on the road, so the feds are looking into these problems".
