What is Transmission Jerking?
1 Answers
When the gear is engaged, releasing the clutch immediately will cause the engine to stall; when slowly releasing the clutch and pressing the accelerator, if the vehicle speed and gear position do not match, gear dragging is likely to occur, causing the car to jerk forward without stalling. Below are the reasons for transmission jerking: 1. Upshift Jerking; because the transmission's response speed is not fast enough, the upshift speed cannot keep up with the accelerator pressing speed, resulting in transmission jerking at the moment of gear shifting. 2. Downshift Jerking; due to the intervention of the energy recovery system, once the driver releases the accelerator pedal or presses the brake pedal, the generator immediately starts working, imposing some burden on the engine, affecting the engine speed, and causing the engine speed to be out of sync with the clutch disc speed, resulting in a jerking sensation. 3. Low-speed Jerking; because at low speeds, the gear frequently switches between first and second gears, and the clutch continuously disengages and engages, making it impossible to smoothly complete power transmission in a short time, leading to common low-speed jerking. There will be a jerking sensation during startup and at low speeds, usually when the turbocharger intervenes at low RPM, affecting the engine speed.
