What Causes Jerking Sensation When Braking in an Automatic Transmission?

[KateDella]

Here are the detailed reasons: 1. When experiencing jerking while driving, the first step is to determine whether it is caused by an engine malfunction or transmission gear shifting. 2. Jerking caused by an engine malfunction typically occurs when the vehicle is driven at low speeds with steady throttle input, resulting in a surging sensation. Common fault points may include the throttle body, spark plugs, or the vehicle's ignition system. 3. Jerking caused by an automatic transmission malfunction usually manifests as a noticeable impact during gear shifts. While mild jerking during gear changes is normal, severe jerking is abnormal. Common fault points may involve the transmission's shift solenoid valve or control module.
