What Causes Gear Shift Jerkiness?

[LucyLee]

Gear shift jerkiness occurs when there is a mismatch between the engine speed and the vehicle speed at the moment of clutch release, essentially creating a speed difference between the engine and clutch. In most cases, the engine speed is lower than the clutch disc speed. To effectively prevent jerkiness, after shifting into a new gear, adjust the engine speed to match or slightly exceed the clutch disc speed when releasing the clutch to the semi-engaged point. Mastering the timing of gear shifts is crucial. Shift gears when the engine speed is around 2000 RPM, first reduce the throttle and then depress the clutch to avoid forced disengagement, followed by shifting. Skipping gears is not recommended. Downshift according to the vehicle speed and your car's specific conditions—downshift when the engine speed drops below around 1500 RPM.
