I would highly recommend the TCI. I have never used a Hughes or Turbo Action. I did have a couple of B&Ms that I roasted fairly easily. Yes, if you start off in first and shift through the gears and remain in 3rd (Drive) as you come to a stop the transmission will maintain its automatic capabilities. If you've been given a rebuilt TH400 I would stick with that. maybe throw a shift kit in it. At approximately 365 hp that TH400 will be just fine. Hope this helps. let me know what you decide. sounds like you're on the right track.
