levelten.com is the best. they can work on any transmission or torque converter. i sent my TC up to them today. $1000 and they will rebuild it to support 1000hp. naturally i wont be that high on hp nor can i launch this frankenstein when im done.......... but just saying
also, they offer a full transmission and tc upgrade to support 1000hp for $7000 just in case u do wanna launch it all the time.
