Change a 904 to manual valve body

Transgo 3 shift kit has served me well for an inexpensive shift kit and shifting option. And I say inexpensive relative to a whole new reverse valve body. If you put the trans go three shift kit in you can just tie back your pressure valve regulator all the way open. I like a quicksilver shifter for my automatic that way I can just ratchet shift. Personally I'm not a big fan of the reverse pattern but that's just a personal preference....
Of course I did that on my duster when I put a 318 and then automatic in it for my wife to race but she never did. It was fun shifting the automatic and you had to shift and start in first and shift all the way up and all the way down.
