    1966 911s Transmission

    I want to know if all the transmissions in the 911s models were 5 speeds, and if they came with 4 speeds how can you tell the 4 speeds form the 5 speeds?..

    Not to be too flippant...but when you drive the car, the standard 4 speed has 4 forward speeds, and the optional 5 speed has five. The vast majority of early cars came with the "optional" 5 speed. If the car has it's original shift knob, a quick glance tells all.

    I just saw the eng/tranny Ian is talking about, theres no way to tell! Ive never seen so much rust on a bumper! The shifter is a black nob without a shift pattern.

    The numbers you have given are casting numbers, not the transaxle Type #, which is the key to identifying it. Look on the bottom for some stamped numbers (not cast-in raised characters). You should find a "902/0" for a USA 4-speed, or a "902/1" for a 5-speed Type # on a '66 911.

    BTW, if it was built 12/66, it is a '67 model year car. I don't think there were any Targas built before the '67 MY, were there? The VIN you quoted in the "Parts For Sale" forum of "500139" would be correct for a 1967 Targa, but unless it has an "S" appended to the serial # (e.g. "500139S"), it is just a 911. The "S" would have a Type #901/02 5-speed trans. as standard equipment.

    The vin tag located under the front hood says this:
    Heizeinrichtung Typ 911 -------S 66 Does this mean anything??

    the bumper sounds like it has R(ust)Gruppe posibilities. sorry could not pass that up.

    get in the car and shift it around. 6 slots would get my vote for a 5 speed.

    That is the tag located on the front crossmember? Here's mine from my '67S:


    The Type# on the left is the one that has the "S" that counts. The "S" after the squiggle and before the "66" on the right I have seen on many non-S models, and it may stand for "Stuttgart" for all I know.

    Glad you figured out the tranny puzzle.
