What is wrong with my vw bug when it wouldn't go into gear?

Is your Bug currently on a level surface? Do this: With the engine off, open the hood and put the car in gear. Then go back there and, with one of your buddies, push the car. If the engine turns (and the car's really hard to push), the car WILL go into gear. If the engine won't turn, the shift linkage is worn out. You get the shift linkage as a "coupler" that mounts on the shifter rod and a rubber bushing. You get to this by removing the back seat base. There's a plate on the transmission tunnel. Take it off, and the shift linkage is right in there. Don't bother jacking the car up; the setscrew for the linkage is on top.

If it's not that, try adjusting the clutch.

If that doesn't work, you'll have to replace the clutch--which means pulling the engine.
