The reasons for jerking during normal constant speed driving are: 1. Clogged fuel system or abnormal ignition; 2. When an automatic transmission vehicle needs sudden acceleration during driving, the driver must press the accelerator pedal deeply. At this point, the automatic transmission will automatically downshift to increase engine speed. When the speed reaches a certain level, it will upshift, causing a noticeable drop in RPM after shifting; 3. Persistent dirt and impurities inside the automatic transmission. Jerking may also occur if the vehicle's computer malfunctions in automatic transmission models, as jerking results from a mismatch between the engine and vehicle speed. Before shifting during driving, consciously releasing the accelerator pedal slightly will prompt the transmission to respond immediately and complete the shift automatically. Then, pressing the accelerator again will engage a higher gear. During this process, if the computer's response is not as sensitive as expected, problems may arise.
