We did some more testing this weekend to find out what happened. When we were putting about 300-350 whp down something did flex inside of the torque converter and probably bent some fins or tweaked something. We hooked up to the lockup solenoid and did quite a few pulls locking it up manually in 2nd, 3rd, and 4th gear and it runs fine under full boost. I'm going to talk to a few torque converter builders and see if they can furnace braze one of my spares. If I can get something done at a reasonable price I may push on with the 03B.
