    The overdrive lock out light is staying on, the button on the shifter
    gives no response. This was at first intemittent, sometimes when
    started the light was on, sometimes off. Now it is always on and the
    car won't shift into overdrive. Most of the driving is in town, and I
    have let it go, now I need it for a highway trip. What is causing

    Will driving it on the highway in 3rd (?) gear at 3500 rpms be bad for

    Relay is bad, you can resolder it or replace it. This always happens
