Im going to put this forward to you so you can decide for yourself,,, I proubly got 400
604 rebuilds under my belt at this time,,, I have replaced only one valve body, I have
serious doubts your transmission issues are valvebody related but most likly
failing transmission related or electronic....Roger HANNIBAL transmission 604 race
transmission and 604 quick change gears...E
