I had a 200 4r valve body given to me that had been in a transmission the guy salvage out for the aluminum case. I knew i had rebuilt a 200 4r for my toy and thought i should have it. It sat in his old shed for a few years and was cleaning it out and though of me and just gave it to me. On the side it has the letters KCZ. Anyone know which car this may of been in. My transmission identifier codes sheet doesn't help me any. Yes, it is a 200 4r valve body. It also has D-10 on it as well.
