What are the reasons for the unsmooth gear shifting in Emgrand?

[VanEthan]

The reasons for the unsmooth gear shifting in Emgrand include: operational factors, clutch factors, and transmission factors. Operational factors: Incorrect operation by the driver, such as a mismatch between speed and gear, can lead to difficulty in shifting gears. This requires the driver to gain experience and improve their skills, after which the problem will naturally be resolved. Clutch factors: Rust on the transmission input shaft, abnormal movement of the clutch driven disc, or poor return can prevent the gear from engaging along the normal path, resulting in difficulty in shifting. Clutch failure, such as insufficient clutch separation travel, can cause incomplete clutch separation and make it impossible to engage the gear. In such cases, it is necessary to go to a repair shop to adjust the separation travel. Transmission factors: Old transmission oil needs to be replaced. If not replaced in time, its lubrication effect will decrease, leading to difficulty in shifting gears. In new cars, the transmission components may not have reached the optimal running-in state, which can also cause difficulty in shifting gears. This issue will naturally resolve after a period of running-in.
