I show you everything you need to know if you want to mate a TH400 to an LS style engine. You will want to check out this build with a Turbo 400 with a LS engine. I had a 6L90 mated to an LY6 and wanted to swap a modern transmission for a more durable one on our race trucks. I chose to go with TCI after some friends gave me a recommendation. So far, I cannot say enough good stuff about their business. If you are interested in one of their transmission you can check them out at
