Why Does an Automatic Transmission Have a Shifting Impact?

When experiencing jerking sensations while driving, it is essential to first determine whether the issue stems from engine malfunction or transmission shifting. 1. Jerking caused by engine malfunction: Typically occurs during low-speed driving with steady throttle application, resulting in a surging sensation. Common fault points may include the throttle body, spark plugs, or ignition system issues. 2. Transmission shifting jerk: Jerking caused by automatic transmission malfunction usually manifests as impact during gear changes. While mild shifting jerks are normal, severe impacts indicate abnormalities. Common fault points may involve the transmission's shift solenoid valve or control module malfunctions.

I've been driving automatic transmission cars for years, and shift shock is indeed common, mainly due to internal transmission issues. For example, insufficient or old, degraded transmission fluid leads to inadequate lubrication, causing friction between clutches and brake bands to be less smooth—shifting then feels like the car is gasping. Additionally, faulty or inaccurate sensors in the computer control system can send incorrect signals, making gear shifts jerky. I recommend first checking the fluid level; if it's dark or has a burnt smell, it's time for a change. Driving habits also play a big role—sudden acceleration or hill starts can worsen the shock, so developing a habit of smooth throttle application helps a lot. If the shock occurs frequently, get it diagnosed early at a professional shop to avoid costly major repairs. Long-term neglect could even lead to transmission failure, which isn't worth the risk. In short, regular maintenance and gentle driving are key to ensuring smooth shifts.

I'm an ordinary office worker who commutes daily with an automatic transmission, and sometimes the gear shifts feel jerky, which is quite annoying. I think this might be related to insufficient or degraded transmission fluid—when the fluid isn't smooth, the system can't function properly. Another reason could be sensor failure, where the computer misjudges the optimal shift timing, making it feel like the car hesitates before shifting. This tends to happen more often during aggressive driving, like accelerating sharply during highway lane changes, so I suggest adjusting habits and avoiding stomping on the throttle. If the car is older, the issue may become more noticeable, possibly due to internal component wear needing replacement. I consulted a technician, and he said changing the transmission fluid every two years can significantly prevent this. Although the jerking sensation might seem minor, ignoring it could worsen the problem—early intervention saves hassle and trouble later.

I just started learning to drive, and the shifting shock in automatic transmissions feels uncomfortable. My instructor told me that this is usually caused by insufficient or dirty transmission fluid leading to lubrication issues. Malfunctions in the computer control during shifting can also cause jerking. The impact is more noticeable when driving fast or accelerating suddenly. Regular maintenance, such as checking the fluid level, is important, and changing to new fluid can improve the situation. It's safer to repair any problems early.
