Car won't stay in gear, Keeps popping out... Options

[6gsillyca]

My car won't stay in gear for some reason. I can get it into first (for the most part) but going into 2, 3, 4, 5, r it won't stay. It pops back into neutral. I pull shift knob back into 2nd, and it just won't stay. If I wiggle/jiggle it a few time in and out I can manage to get it to (somewhat) stay in, but it doesn't seem to be in gear very good. Like when I am able to get it into gear the SLIGHTEST bump on the shift knob will knock it back out into neutral. Usually you can push the knob with a bit of force before the tranny will "pop" the gear back into neutral. Clutch fully depressed doesn't help either.

1st and 3rd are able to go in but dont stay very well (come out easily). 2nd is hit and miss (haven't found a way to "jiggle" it in). 4th needs to be wiggled around to get it in (while pulling back, can't pull back straight, need to wiggle and pull back to get it in gear), and reverse is hit and miss.

Idea's?
