What is the correct way to shift from third gear to second gear?

[ChaseLee]

The correct method for shifting from third gear to second gear is as follows: When the speed reaches 20 km/h, press the clutch, release the accelerator, and shift to third gear. Below is relevant information about gear shifting: 1. Gears: There are gears of different speeds on the tire's rotating shaft. When the engine speed remains unchanged, 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. 2. Torque: According to the knowledge of torque, at low speeds, the gear is larger, and the engine drives a large radius with a small radius, allowing the car to obtain greater driving force. At high speeds, the engine drives a small radius, resulting in a fast circumferential speed, meaning the car moves quickly but with less torque, i.e., less driving force. Therefore, shifting gears in a car essentially changes the transmission gears.
