What Causes the Jerking Sensation When Shifting Gears While Driving?

[AdalynnRose]

Driving with a jerking sensation during gear shifts is caused by the transmission oil not being replaced in time, leading to changes in its performance. Below is relevant information about gear shifting: Gears: The tire's rotating shaft has gears for different gear positions. When the engine speed remains constant, engaging gears of different sizes (different gear positions) with the engine results in the larger gear obtaining a lower circumferential speed than the smaller gear. Torque: According to the principles of torque, in lower gears, the larger gear allows the engine to drive a larger radius with a smaller radius, providing the car with greater driving force. In higher gears, the engine drives a smaller radius, resulting in a faster circumferential speed, meaning the car moves faster but with less torque, i.e., less driving force. Therefore, shifting gears in a car essentially changes the transmission gears.
