    Help ID Transmission

    I was hoping for more understanding on the transmission in my car. Any help would be appreciated.

    My 1972 911T is an early build and sometime I find discrepancies between the car as built and the parts manual. According to the V-Pages my transmission should have numbering that follows the 732 0001>> convention. While mine is beat and scared up some, it appears to read 7150828.

    I see in later year V-Pages that these numbers are for a "911S 915.40 75 5 715 0001>> 5-SPEED" It still has the mech speedo.
    What are the particulars of the 1975S transmission?

    See pictures.

    Any help would be appreciated.
