It is not normal for the Mercedes-Benz 260L to have a jerking sensation when downshifting. The reasons for the jerking sensation in a car are as follows: Transmission causing the jerking sensation: The main function of the transmission is to change the speed ratio between the engine and the wheels and to expand the range of speed changes, thereby adapting to speed variations in different environments. Therefore, the transmission can reduce this jerking sensation to some extent, making the power output smoother. Generally, the better the match between the transmission and the engine, the less noticeable this jerking sensation will be. Internal engine faults: For example, if components inside the engine such as spark plugs or ignition coils fail, it can cause the car to lack acceleration during driving or even experience severe shaking and jerking sensations. Additionally, if the fuel pump becomes clogged or malfunctions, the fuel pressure will drop, preventing the fuel from properly atomizing and burning. On one hand, this may lead to carbon buildup in the car's engine, affecting its lifespan, and on the other hand, it can cause the car to drive weakly, resulting in noticeable jerking sensations during gear shifts.
