Sounds like you are screwed. You tuned, race and *(&'d up your car. You could jump on the "it's the MT82's fault" bandwagon though... others in your same position have. In fact, I think one of the very first reports of a bad transmission on the NHSTA's site with "issues" was someone that was racing their car and crashed it.
Good chance to put something else in fun down there though.
