    Buba's '83 Suburban, 350 engine, lost 2nd and 3rd gear ??? Clear out of the blue. No sliding in and out...just 1st, n, and R. When you think it should it should shift...it don't. I think it may be a vaccum or the modulator.

    Where is the vaccum line attach to the transmission and where does it go to???

    The idiot that had the vehicle pulled and plugged most of the vaccum lines!

    Thanks for your help in advance...You guys have never let me down!!!

    Wally, I had that happen one time with a chevy 350 Turbo tranny. It wouldnt shift into 3rd. No noise or anything, it just wouldnt shift.
    3rd gear was broken clean in half.

    You can probally drop the pan on that tranny and tell alot about it by what you find in the pan.

    The good thing with that year model you have is I doubt it has overdrive.
    Alot cheaper to rebuild then an overdrive if it needs it.
