    Hey guys!
    I've got a 1975 camaro with a v8 swap that is just about done. I've been working on it for quite some time now and I'm almost ready to fire the new motor. The problem that has stumped me is my floor shifter is locked in park. The column shift linkage rotates fine if I put my hand on the column and manually operate it. The cable linkage is just dangling under the car right now (just finished rebuilding the th350). I can't think of what is keeping the shifter in place. Is there some sort of shifter lock connecting to the brake in these cars? Or am I need of a new shifter cable? Ive tried with the key in the ignition and my foot on the brake but nothing. In my mind it should move without resistance because none of the linkage is hooked up. Everything related to the floor shifter is stock from 1975. Thanks for your help and I'll get some pictures of the project posted here soon.

    the shifter should move when you push the button down on the top of the handle. if it isn't hooked up to the trans or the linkage that runs to your column it should move freely. there is no lock hooked up to the brake and you don't need the key on. maybe take the cable off the shifter and see what happens. could be a stuck cable like you mentioned.

    I had that problem years ago in a 2nd gen. If everything in the car isn't grounded quite right, it takes the path of least resistance. In my case, the shifter cable became the ground. Fixed the grounds and replaced the cable and it was fine.

    Is the cable connected to transmission lever?

    The cable is not currently connected to the transmission lever. Is there a way to loosen up the transmission cable once i've got it off.

    Xten I think i lost you a little on the grounds issue. Are you saying that a lack of a engine to chasis ground could cause the cable to become the ground and have issues?

    Yup.
    The engine is isolated from the body with rubber mounts. The cable can become the main ground through the transmission case.
    It will heat the cable and melt the sheath then the cable sticks to it when it cools down.
    Contact with an exhaust system can have the same result.

    Remove the cable and see why it won't move.

    I've had headers melt the cable before, including once on the starting line :(

    KISS, remove cable, test shifter & cable separately, easy peasy.

    Bad cable probably related to the ground issue
