That sucks, Dirty...same thing happened to me a couple years ago. I had a trans built, slapped it into the Camaro and left...get to Norwalk (750+ miles one way), and it won't shift to 2nd under power...bad intermediate sprag. Come to find out, the trans guy decided to switch brands of sprags, and my tranny was the guinnea pig (without me knowing it)...so, out it came, for another rebuild. The ball buster was, my next trip to Norwalk resulted in yet *another* trans problem with the same transmission! I got less than a handful of runs on over 3,000 miles worth of driving...the only 2 times I've EVER been to Norwalk.
Anyway, back on topic...I hope you get yours squared away, and I hope everyone is running well at US131...
