200 4R Install Questions.

The 200-4R isn't junk. I'm taking it to the transmission shop and letting him drive it Monday. I've beaten the crap out of this transmission for three plus years. Track racing, street racing, rolling burnouts, the whole works. It takes it all. I run 4.10 gears and had it at 145 with more to go. The steering and suspension, not to mention the brakes got scary at that speed. Something happened to mine, and the more I talk to people, I think it's the converter. I'll definitely go custom if that is the problem. I'm already looking.
