It's a auto/manual valve body TCI Streetfighter with a bolt in sprag supposedly.




Unless a valve body is specifically built as a manual shift valve body all valve bodies are auto/manual.

As far as the bolt in sprag in your TCI transmission, it's more than likely just a standard sprag with a bolt in outer race. It will not stop the rollers from rolling under, only the A+A or Coan super /Ultimate sprags are designed to stop that from happening. It's a total waste of money and effort to remove the outer race from a trans that does not have a loose outer race and replace it with a bolt in outer race.
