What Causes Transmission Jerking?

[StellaMarie]

Causes of transmission jerking are as follows: Upshift Jerking: Most cases are due to the transmission's response speed being insufficiently fast, where the upshift speed cannot keep up with the throttle input. Therefore, at the moment of gear shifting, a jerking sensation occurs. Downshift Jerking: This is mostly caused by the intervention of the energy recovery system. Once the driver releases the throttle pedal or steps on the brake pedal, the generator immediately starts working, engaging the engine and imposing some load on it. This affects the engine speed, causing it to be out of sync with the clutch plate speed, resulting in a jerking sensation. Low-Speed Jerking: Many vehicle owners experience this issue. During low-speed driving, frequent shifting between first and second gears causes the clutch to continuously disengage and engage. The power transmission cannot be smoothly completed in a short time, leading to common low-speed jerking. Jerking sensations occur during startup and low-speed driving, typically when the turbocharger engages at low RPMs, affecting the engine speed.
