I'm glad we did since he said a few seals were fubar'd from the previous installer. No computer needed, just add a vacuum line and shift like a manual. No TV cable either.
We went that way because we thought we might like the OD if in Low range, he 1st gear is deeper at 3.0 than the 2.5 of the TH350/TH400, and we got a good deal on it with the adapter already installed.
AlumCJ runs a 4L80E built by Tranny Tom with the Trans Go valve body kit in it, too. I think he had a checkup on it this year and all was well inside on a built up LS2 racing Ultra4 events.
I would go with either of those choices.
that was my other thought. i didnt know i could run a full manual valve body and not run electronics
