Is the Jerking Sensation Caused by the Transmission or the Engine?
2 Answers
The jerking sensation is caused by the transmission. Some cars have transmissions with poor shift smoothness, and in some cases, the mismatch between the transmission and the engine can also lead to jerking. The transmission is a crucial component of a car's powertrain; without it, the car cannot operate normally. There are three common types of automatic transmissions in cars: AT (automatic transmission), dual-clutch transmission, and CVT (continuously variable transmission). The dual-clutch transmission is currently a popular automatic transmission, which is actually developed based on manual transmissions. In a dual-clutch transmission, one clutch controls the odd-numbered gears, while the other controls the even-numbered gears. Dual-clutch transmissions are known for their fast shifting speed and high transmission efficiency.
After driving for so many years, most of the jerking sensations I've encountered are related to the transmission, especially in automatic vehicles when shifting gears during acceleration—it can cause that shaky feeling. Engine issues, such as aging spark plugs or insufficient fuel supply, can also lead to similar symptoms, but these are relatively less common. Therefore, it's best to prioritize checking whether the transmission fluid has expired or the level is low. If the car frequently jerks, it's likely due to transmission wear—get it inspected at a repair shop as soon as possible. Neglecting it long-term could damage more components. During regular maintenance, pay attention to changing the transmission fluid, such as every few tens of thousands of kilometers, to avoid most problems. In short, don't procrastinate—safe driving is the top priority.
