What Are the Reasons for Difficult Gear Shifting in Manual Transmission?
3 Answers
Here are the related explanations for the reasons of difficult gear shifting in manual transmission: Operational Factors: Incorrect operation by the driver, such as speed and gear mismatch, can lead to difficulty in gear shifting. This requires the driver to gain experience and improve their skills, after which the problem can naturally be resolved. Clutch Factors: Rust on the transmission input shaft can prevent the clutch driven disc from moving normally, causing poor return and making it difficult for the gear to engage properly. Clutch malfunctions, such as insufficient clutch release travel, can result in incomplete clutch disengagement, making it hard to shift gears. In such cases, it is necessary to visit a repair shop to adjust the release travel. Excessive clutch gear lock force can also cause difficulty in shifting in and out of gears, requiring adjustment of the clutch cable and gear lock at a repair shop. Transmission Factors: Old transmission oil needs to be replaced. If not replaced in time, its lubricating effect will decrease, leading to difficulty in gear shifting.
Difficulty in shifting gears with a manual transmission, I think the most common issue is not depressing the clutch pedal fully. After driving for decades, I've noticed that beginners or those with poor driving habits often only press halfway, causing gear shifting to be jerky. If the synchronizer is worn, you can hear a grinding noise when shifting, especially during cold starts when low oil temperature exacerbates the problem. Old or insufficient transmission fluid is another reason; I recommend regularly checking the fluid level and color, as changing to fresh oil can improve the situation. When driving, don’t hesitate—fully depress the clutch before shifting to reduce gear friction. For safety, difficulty in shifting can lead to loss of control on mountain turns, so don’t delay repairs.
I often experience rough gear shifting in my manual transmission city commuter car, with noticeable jerking. After inspection, it was found that the clutch pedal might be worn out, resulting in insufficient pedal travel. The internal linkage components need lubrication, as rust or bending can make the action stiff. When the transmission oil viscosity is too high, especially during cold starts in winter, the situation worsens. It is recommended to warm up the car for a few minutes before driving to raise the oil temperature. Don't ignore these minor issues; prolonged neglect can lead to expensive repairs like replacing the synchronizer rings. Be decisive in your actions: ensure the clutch is fully depressed before shifting gears, and avoid hesitating in the semi-engaged state. Regular maintenance of the transmission system is the way to save money.
