Anyone local to me capable of correcting errors on a 904 race build

I had a similar experience with a local builder in Oklahoma. The trans failed in under a mile. Removed it, he rebuilt in again. I got about 10 easy miles on it before it self destructed. I pulled it out, and he blamed it on me and refused to warranty it again.

I took the trans apart and built it myself. It had many issues with it. I talked to Cope and bought most of my parts including a valve body from him. It has worked great.
