I just picked up my transmission from the rebuild shop and it was supposed to get a good performance rebuild and a TCI valve body. It was a stock transmission from a 74-75 truck that I had installed a transgo shift kit into Everything had worked fine and I was happy with the shifts until 3rd eventually started slipping. He recommended the TCI valvebody and said it's the only thing he uses for anything performance.
So, I just pulled the pan to install my filter extension and deep pan and the valvebody looks completely stock. It has dodge casting numbers, 1973 date code, etc. I pulled it out to inspect it and it is not my original valvebody since transgo requires a couple modifications like drilling and grinding. The TCI picture on summit shows gold zinc plated parts and a red separator plate, mine is all raw steel. I plan to call TCI and talk to them and talk to the builder on Monday. But was thinking someone on here might have experience with them. Is there anyway to identify if it is a TCI part and do they cast new valve bodies or modify originals?
