    Sorry I missed this post but basically not much, I suggest an extra direct clutch, a high carbon overdrive band and the sonnax pin on the overdrive and definately use the spiral retainer on the intermediate. The valvebody I suggest a better pressure regulator and/or the line pressure booster kit.

    This sounds like a fun project, Going to a controller or manual valvebody?
