    Can you identify the year & model?

    Can anyone identify the year and model for this early 911 or 912 transmission? Serial number is 3280201.
    Thank you.

    It would be easier to identify the transaxle by the type number rather than the serial number. It is stamped on the case.
    1970 911S Coupe (Burgundrot) (sold)
    1967 911 Coupe (Light Ivory) (mostly gone)
    1966 911 Coupe (Sand Beige) (sold)
    Van Diemen RF99 Formula Continental
    Citation F1000 on the way
    Van Diemen Hayabusa SCCA Formula S (sale pending)

    Case code

    I have the number (902/1), but i have 2 factory Porsche charts that show the same case code for both early 911's and 912's. That's why i'm trying to see if the serial number will determine which application the case was used for.

    Here's the link for the charts. Scroll down and see charts #1 & 2 and you will see the conflicting, confusing data.

    See my dilemma?

    The Factory Tech Spec book indicates that this is a 5-speed transmission from the 1968 model 911's.

    Gear ratios are:

    1st 11:34
    2nd 18:34
    3rd 22:29
    4th 25:26
    5th 28:24

    Ring & pinion 7:31

    Early 911S Reg #753
    R Gruppe #105
