What is the difference between D gear and M gear?

[CorbinLynn]

Here are the main differences between D gear and M gear: 1. M gear is the manual mode; D gear is the automatic mode. 2. When using D gear, the driver only needs to control the accelerator pedal, and the transmission computer will automatically control the upshift process; when the gear is in M gear, the driver needs to move the gear lever to upshift, otherwise the transmission will only stay in the current gear and will not upshift automatically. Below is an introduction to more gears: 1. P gear: After parking, shifting into this gear can prevent the vehicle from rolling backward, especially when parking on a slope. It is essential to shift into this position and use the handbrake together to prevent the vehicle from rolling backward, which could cause injury or accidents. 2. R gear is the reverse gear: This gear can only be engaged after the vehicle has come to a complete stop and is used for reversing the vehicle, such as when backing into a parking space or parallel parking. Engaging the R gear before the vehicle has stopped completely may damage the internal components of the transmission. 3. N gear: This gear is generally used when waiting at a traffic light. Using it together with the handbrake makes it even safer. However, coasting in N gear is not recommended. Although it may save some fuel, a vehicle without power becomes very passive in the face of sudden situations, lacking a sense of security. 4. D gear is the drive gear, also known as the forward gear. When the gear lever is moved into this gear, the transmission automatically shifts up and down within the engine's speed range, with the shift points depending on the engine load, the driver's driving style, and the vehicle speed. 5. S gear is the sport mode. In this gear, the transmission can shift freely, but the shifting will be delayed. The purpose of this is to keep the engine at high RPMs for a longer time, thereby increasing the vehicle's power.
