    Try starting in neutral, at a stop. Then shift to 3rd and see if it engages and can move the car . Were you tricked by the seller when buying it?The tran fluid should not be brown lookinh. Brown is sign of over heating internal parts. Red is no over heating. Look for fine metal on the stick too.

    Try looking at the trans oil on the stick after the car has warmed up.It red normal, if it shows brown and sells , you can sniff it, then somethings inside the transmission has gotten hot and turned the tran oil brown. Once you rule out or rule in the oil color, You can conclude its needing a rebuild or its not needing a rebuild. With the non function your tran shows, I say it need a rebuild and can know more by the oil color. Please do this and write back

    My first guess is the neutral safety switch which is really the shift selector. The first versions sent out were not well sealed up. A revision came out that has a orange gasket between the two halves, if an OEM part. Its easy to see. Even then, being so old the updated version could have failed by now. But if you look under and see the original switch, its very likely the problem.
    Very easy fix.

    In this image, you can see the orange gasket. I can not seem to find a write-up right now, but there are some out there. Do it with the car in neutral as the switch is marked for install in that position AND its sorta "adjustable", meaning the holes for both bolts are enlongated. Make sure marks line up and tighten down.
