Yes I believe he still has the stock rear and tranny but I bet the tranny doesnt last long

The tranny will be the last thing to go. If it's an M6 car (and I'd bet that it is if it's running 480rwhp and 190mph...I won't restate my doubts about those numbers ), it's got a beefy T56 in it. The T56 in the LS1 cars is pretty damn stout. The worry isn't the tranny itself, but the clutch. GM doesn't put an overly strong clutch in those cars considering an '01-'02 M6 car (with LS6 intake and other little changes) will put down ~310-320rwhp bone stock.
The rear will let go first if the car is on anything other than radials. The 7.5" 10-bolt in those cars is pretty wimpy. Problem is, to upgrade to a 12-bolt or 9" in an LS1 is well over $2k.
