What Causes the Jerking When Shifting to First Gear in a Manual Transmission Car?

[VonDaniel]

Here are the reasons for jerking when shifting to first gear in a manual transmission car: Clutch Issues: First, it could be due to rust on the transmission shaft, preventing the clutch driven plate from moving properly and returning poorly, which makes it difficult for the gear to engage normally. Alternatively, a clutch malfunction may result in insufficient clutch separation, leading to incomplete disengagement and difficulty in shifting. In such cases, it is recommended to visit a repair shop to adjust the clutch separation travel. Transmission Issues: First, it might be because the transmission oil needs replacement. Like engine oil, transmission oil is also gear oil. To some extent, gear oil in the transmission requires regular replacement. If not replaced in time, its lubrication effectiveness will significantly decrease, increasing the resistance when shifting and making the gears feel stiff. Or, in colder temperatures, the viscosity of the gear oil in the transmission may not reach the optimal state, naturally resulting in poor lubrication and causing a jerking sensation when shifting gears.
