900hp and stock transmission

[Thirdgen89GTA]

Thanks Eli, I'd wondered about that. When I read that it was a Chevy trans, I figured that it must have been a 700R4 or 4L60 the way it came apart

4L60's can hold a decent bit when built, but will never be as strong as a TH400 or 350.

Even if someone didn't post the info from that forum, I'd have debunked the stock trans theory. There is no way a stock trans would have even lived long enough to shatter like that behind a 900hp engine. Would have started slipping long before it went kaboom. Seeing as how the 4L60 in stock trim is only rated for about 400hp. I won't say that there is a person stupid enough to run a stock trans behind that much power though, i've seen stupid people and wouldn't put it past some of them to try it.
