www.performanceautomatic.com they have a trans that has a life time warranty, even if it wears out you just pay the freight and they will "freshen it up" for free.
they are a little pricey though, the one with the lifetime warranty comes with everything, including trans brake.
btw: its the "super comp"
a buddy of mine just ordered one, ended up costing him around $3000 with converter, bellhousing, flywheel, BASICALLY EVERYTHING
