What causes two jerks three seconds after releasing the throttle?

[LaylaLee]

Jerking after releasing the throttle could indicate an issue with the transmission. It's advisable to check if the transmission fluid is low or has deteriorated. If the transmission fluid is fine, it's recommended to visit a professional repair shop or a 4S dealership to have the transmission control system inspected. Generally, when the engine speed and vehicle speed just meet the gear-shifting criteria at low speeds, the upshift jerk can be more pronounced. If the throttle is slightly larger, making both engine speed and vehicle speed significantly exceed the shifting standard, the gear-shifting jerk will be less noticeable. For manual transmission cars, jerking during throttle application and gear shifting is largely a matter of driving technique, often due to uncoordinated clutch and throttle operation or releasing the clutch too quickly when starting. The main issue with manual transmission cars occurs during downshifting. Many beginners often fail to shift gears correctly when decelerating and downshifting, causing gear dragging which results in vehicle jerking.
