What Causes Difficult Gear Shifting in Manual Transmission Cars?

[DeAmelia]

Difficult gear shifting in manual transmission cars is generally caused by the following reasons: 1. Operational issues: Some beginners may not depress the clutch pedal fully or release it too quickly during gear shifting, resulting in rough gear changes. 2. Shifting in semi-engaged clutch state: Gear shifting is prohibited when the clutch is semi-engaged. The clutch must be fully depressed for successful gear shifting. 3. Rusty transmission shaft: Poor return or engagement due to rust can prevent gears from engaging along the normal path. This requires disassembling the transmission gears to add lubricating oil. 4. Expired transmission oil: Manual transmission cars typically require transmission oil replacement every 20,000-30,000 kilometers. Failure to replace it in time will significantly reduce lubrication effectiveness, greatly increasing shifting resistance and causing issues like stiff or stuck gears. 5. Clutch pressure plate failure: A deformed or worn clutch pressure plate can lead to poor clutch separation and difficult gear shifting. In such cases, it is advisable to replace it with a high-quality pressure plate that matches the original vehicle specifications.
