After much reading and studying (this book is great: http://www.amazon.com/Modify-Hydra-Matic-Transmission-Motorbooks-Workshop/dp/0879382678 ) and getting recommendations from folks over on PSP http://psp.aquacomp.net/default.asp . I dropped the car off at http://jakesperformance.com/Home_Page.html in Sanger for him to go through and do one if his Stage II transmission builds on.
He's also going to tweak the governor to raise ths shift points a little, and add an auxilliary trans cooler. Plus he'll open up the converter and make sure it's not damaged/contaminated.
I was set to do all this myself, but after talking with him I learned that the Trans-Go shift kits are "ok" for most regular street engines but once you start getting close to 500 HP they can have problems supplying enough bite to the direct clutch. He has his own valve body calibrations he's developed for his Stage II builds. Plus, he replaces the rear thrust washers with a Torrington bearing, uses the 34-element intermediate sprag (which I'm supposed to already have, but I have my doubts), and adds an additional clutch plate to the intermediate and direct clutch. We talked quite a bit about the various types of clutch frictions and he convinced me that he knows his stuff. He runs all his builds on a transmission dyno to check them out before delivering them. Add to all the above the fact that a good set of bushing drivers is crazy expensive, and you have the reasons I decided to let him to do the work.
I'll know in a couple of weeks or so.
