TH400 Rebuild Part 3: Case Mods for Hipster Brake and Gear Set/Center Support w/Roller Case Bearing

Not a professional transmission builder. This is my 2nd TH400 with Hipster Trans-brake build. I clean the old gasket off the valve body area. I do some case modification for the Hipster Trans-brake and Case Saver. And do the overflow tank drill tap modification for the overflow tank. Then install the gear set and center support with a roller bearing in the back of the case.
