Keeping in mind that I can't see or hear it for myself, I think this tech knows what he's doing. From what you wrote I suspect that he is correct that the trans had a mechanical failure that caused the overheat.
A temp gauge would have given you a little warning, but in no way would have saved this transmission. I think the first thing that happened is that something broke, then the temp started to go up. A gauge might
have given you enough warning to stop and cool the trans, which possibly could have prevented the tow, but not the failure.
