I ended up going with the local shop Mass Diesel Performance to rebuild my trans to a stage 2 with a triple disc tc. The price was right and there is a 2 year warranty. Hopefully it works out good. They had good reviews
It's going to be raybestos and alto clutches, and a performance diesel tc. Synthetic fluid. I'm not sure on the solenoids. I am not 100% sure but he assures me it will hold up at 600rwhp.
After finally scattering the 185K stock trans I'm building myself a new Stage 2 with a few new pieces in the PR body and valve body I've been wanting to try. If my ideas work like I think they will I'll start offering them in our trans builds. That's all I can share for now.
