Anyone rebuilt and upgrade auto trans for LS1?

just wondering, whats involved, and sort of cost to do it?
essentially upgrade is for it to take more power....

thanks

The 4l60E is the weak link. When I supercharged it the tranny lasted 200 miles.
Went for Raptor rebuild kit: http://www.transmissioncenter.net/4L60E.htm Speak to Todd.
