How to Shift from D to S Gear in an Automatic Transmission?

[McLondyn]

Shifting between D and S gears is not affected by vehicle speed or road conditions, nor does it require braking, and can be done at any time. Here is relevant information: 1. The automatic transmission D/S typically represents the shift between D and S gears. The so-called D gear is the drive gear, an abbreviation of the English word 'Drive'. When the gear lever is moved to this position, the transmission automatically shifts up or down within the engine speed range, with the shift point depending on engine load, the driver's driving style, and vehicle speed. 2. The S gear is the sport mode of the D gear, offering more powerful output. In sport mode, the transmission can shift freely, but shifting is delayed, keeping the engine at high speeds for a longer time, thereby increasing vehicle power. 3. The D gear is the most commonly used driving position. It's important to note that since the automatic transmission determines the gear based on throttle size and vehicle speed, the method of operating the accelerator pedal affects the shifting speed. If the accelerator pedal is pressed quickly at startup, upshifting is delayed, enhancing acceleration capability. Once a certain speed is reached, quickly releasing the accelerator pedal allows the car to upshift immediately, resulting in reduced engine noise and improved comfort.
