i bought a 86 gt mustang a guy was building for a race/street car with no motor. The tranny was in it so I pulled it out. He says it was built by tci, It has the tci sticker on top. I was wondering if there was anyway to tell what series of tci tranny I have? The servo in the passenger side has an R on it and stamped fomoco. I thought a r servo came in c6's. Anyway I just want to know what it is. He also says it has a full reverse manual valve body.
