    Have a 68 mustang auto with 200 and am trying to figure out where the vacuum line goes on the c-4 tranny. The vacuum line fell out and I cannot figure out where it goes? Slow person needs help.

    there should be a vacuum modulator (metal cylinder) visible on your transmission. You need to get underneath the car.

    sometimes its a brass like color...unless its all dirty. It looks like an oil sending unit.

    On the top side it goes to a full time vac port off the intake manifold.
    they already posted where it goes on the bottom.
