    Unbolt it??

    I don't remember exactly where and what bolts there are but it's not rocket science.

    iirc mine was 3 13 mm bolts holding it down. they may have a torx head in the middle of the bolt. whats throwing you off.

    Once you remove the top half of the box, you can probably just pull up on the bottom half briskly to pop it loose. It has drive rivet type push clips holding rubber bushings to the box. If you lift up the PCM you see the heads of the clips. Don't mess with it from underneath, just yank the box up and the bushings pop out of the sheetmetal holes and stay attached to the box.
    All Grand Prix, all the time. 69 Model J, 99 GT & GTP coupes. All junk, haha.
