I'm looking for some insight into the approximate date for an auto trans. Based on sheet metal dates, engine date, etc., I have concluded my 6S1645 was built in early to mid-March, 1966. The auto trans I currently have is an original K-code Hi-Po auto trans with the fat "C" servo and the original metal tag with an August, 1965 build date. Is it possible this could be the right trans build date range for my car, or would this be too early? If it is too early, what would the appropriate date range be for a March, 1966 Shelby auto trans build be? Any information would be greatly appreciated. Thanks.
Doubtful that yours is original to the vehicle. Our original C4 for 6s1467 is dated "6B4" (February 4, 1966).
