You've successfully beaten me almost all the way to the 4L80E. If you would though, lets perform a thought experiment. Forget about all the custom that has to happen for this swap for a moment, because my brother is handling all of that and could probably be a pro mechanic if he wasn't already a network engineer. But lets set all the custom aside and look at just the transmissions. Mechanically why would a TR400 be less reliable than a 4L80 with triple the miles? Nobody has explained that. Everyone is fixated on the fact that there's some custom fab, and wiring that has to take place, and the trans brace has to move and shortened driveshaft and so on. I'm really not trying to be a pain, I want to understand why. "it's newer" doesn't really explain anything
Because mileage isn't everything, you don't know if that 4L80 has had a refresh somewhere along the way, and they're not guaranteed dead or even almost dead at 250,000 miles. If it works it works. It's a stout box.
