Why Can't the Manual Transmission Car Shift Out of Gear?

It could be due to a clutch malfunction or a synchronizer issue. Manual Transmission: Manual transmissions are equipped with synchronizers, which ensure that the driving gear and driven gear rotate at the same speed, allowing smooth gear engagement. If the synchronizer is damaged, the transmission may become unable to shift gears.

If the clutch is damaged, replacing the clutch pressure plate may be necessary. The pressure plate contains a diaphragm spring, and if this spring is damaged, the clutch may fail to fully engage or disengage.
I've been driving manual transmission for almost ten years, and most gear disengagement issues stem from the clutch. First, check if the clutch pedal is fully depressed - sometimes overly thick floor mats can obstruct pedal travel, or air in the clutch hydraulic line may cause incomplete disengagement. Transmission fluid that hasn't been changed for too long becoming viscous, or rusted/stuck shift linkage are also common causes. Once my car stubbornly refused to come out of second gear at an intersection, and it turned out the shift cable boot had cracked allowing water ingress that froze. Try restarting the engine, rocking the vehicle slightly at idle while depressing the clutch - this often provides a temporary solution. Before long trips, remember to spray some rust inhibitor on the shift mechanism as preventive maintenance.
