What is the reason for not being able to shift gears after starting a manual transmission car?

[LeoRose]

Manual transmission car cannot shift gears after starting for the following reasons: Clutch disc not fully disengaged: When starting the car, even after pressing the clutch pedal all the way down, you still feel difficulty shifting gears or, although you manage to force it into gear, the car moves forward without lifting the pedal or causes the engine to stall. This can be resolved by adjusting the clutch at a repair shop. Pressure plate damage: If the clutch disc or clutch pressure plate is damaged, when starting the car and lifting the clutch, you may feel unevenness, a jerking sensation in the car, and a rough feeling when pressing or lifting the clutch. It is recommended to replace the clutch friction disc with a new one to resolve the issue.
