Does the 2011/12 Shelby have the Tremec transmission (made in Mexico) or the MT82 (made in China)?

I was curious, how the 2012 Mustang Shelby's shift and if there's any problems with them that should be aware of?

Thanks so much in Advance.

Tremec and like all mustangs ever produced, the shifting improves threefold with an aftermarket shifter (MGW).
