The four-speed manual transmission has failed. No warning. I start it up, shift it into reverse, and it won't leave. The stick moves around, it's no longer in the reverse position, and it won't shift into any gear now. If I release the clutch, the car goes into reverse, so the reverse gear is obviously engaged. The reverse lights also aren't on. Seems like a linkage problem, anyone else with this problem, or know how to solve it?
