    1954 trans casting number

    i am a new owner of a 1954 Corvette. The casting number on the bottom of the trans reads: S702602 GMC E114. Is this the trans original to the car? Thanks! Joe Kovarik

    Joe if you provide the vin someone could help confirm if it'd be close enough to your car build. The c1registry.com site birthday calendar will tell you the approximate date it was built.

      The answer is no.
      Also in 54 cars were built the entire year starting in Late 53 - the birthday book is 100 percent wrong. As judges we know as there are casting dates and parts dated past June/July 1954. 53 - cars were built all calendar year - 55 cars were built all calendar year with much LOWER production numbers. If you do post a VIN I can tell you roughly when that car was built - Thanks Chris TiN Restorations Plano IL

          Chris, the VIN is #4304. Also, yesterday I was talking with Cary at D&M Corvette. I had a question about my speedo not working. He gave me your phone number. I'll call you after Christmas. Thanks! Joe

                Chris, thanks for the photo! I am mostly just curious about the engine and trans. I am a cruiser so my cars are driven a lot. My cars are not 'trailer queens' and I don't care about 'flight status'. I had the carbs rebuilt and the car runs good now. Cary from D & M corvette removed them and brought them to a place in Schiller Park that rebuilds carbs. I have four other classics and I got out 103 times last year. I will call you about a speedometer that doesn't work. Thanks, and Happy New Year! Joe

                  Hi Chris! The tail end of my 54 transmission has these stampings. Any thoughts on what these might indicate?
