Wont shidt into gear

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your '99 Cavalier is stuck in neutral and won't shift, there are a few suspects to check out. If it's a manual transmission, the clutch might not be fully disengaging—this could be due to a worn clutch, a faulty clutch master/slave cylinder, or low hydraulic fluid. If it's an automatic, the issue might be with the shift linkage or a transmission issue, such as a failing solenoid or low transmission fluid. A quick check under the hood to make sure the shift linkage is intact and properly aligned is a good place to start. Also, take a look at the fluid levels—if they're low or the fluid smells burnt, that’s a sign the transmission may need professional attention. If everything looks fine, it might be time to get the transmission's internals inspected.
