  • Speedo / Tach / Gauges: Avanti Speedometer Cable Question

    How do disconnect the speedometer cable from the transmission?
    I have a 1964 Avanti. The speedometer was not working, so I replaced it, but the new speedometer still didn't work, so I removed it. Then I drove a short distance and determined that the cable is not turning.
    Do I have to disconnect the cable from the transmission and if so, how do I do it? I can't see the cable from the sides of the transmission, so am not sure where it attaches. Incidentally, I don't have a lift, I am raising it on some ramps only.
    Any help is greatly appreciated, as I am not a mechanic. Thanks. Bill

    The speedo drive cable runs inside an armored cable that goes into the left side of the transmission. The armored cable’s got a bullet shaped end inside the trans and is held in place under a metal tab & 3/8’s bolt.

      Look in the tail section on the driver's side for the cable skyway mentioned. Transmission fluid will come out when you remove the cable so be prepared.

        Thank you both for the information. I have been away for the last two weeks. I plan to tackle this problem this week.
