Friend of mine just got his redone at a tranny shop. Got a new billet torque converter, valve block(IDK what that means) and new clutches. He said it cost about $2500 by the time he got it back, but now it works perfectly and has a one year warranty. He said that it is supposed to be good for 500 HP, but he has no plans to warm up the motor-figures the tranny should last forever.

Check back in a couple years and I'll know if it has worked out like he hopes.
