You really think he accepted resposibility? Give me a break. Whoever put that transmission together had no business touching one in the first place. There's no way I'd send it back to a shop who had proven themselves to be so incompetent. A fair resolution to me would be a refund for the labor portion of the "build" (hesitant to even use that word), as well as a refund for any parts that were damaged as as result of the incompetence. I would bet a large sum of money that CRT loses MUCH more cash as a result of this thread than if he just manned up, apologized and offered at least a partial refund in the first place.
