What is the introduction to the gears of a manual-automatic transmission?

The introduction to the gears of a manual-automatic transmission is: 1. M stands for manual mode; 2. P stands for parking gear; 3. R stands for reverse gear; 4. N stands for neutral gear; 5. D stands for drive gear; 6. S stands for sport gear. Both P gear or N gear can be used to start the vehicle, and the engine can be turned off in any gear. A manual-automatic transmission is a transmission device that combines the functions of manual and automatic transmissions. The method of using the manual mode of a manual-automatic transmission is: directly shift the gear to the manual mode, i.e., the M position, and moving the gear lever towards the plus or minus signs can increase or decrease the speed. There is no need to press the brake or release the accelerator when switching to manual mode.
I've been driving an automatic transmission car for several years, let's talk about the gears: P is the parking gear, engaged after stopping and turning off the engine to lock the transmission and prevent rolling; R is the reverse gear, used for backing up, requiring careful operation with the brake pedal; N is the neutral gear, briefly used for towing or idling; D is the drive gear, the main gear for daily driving, which automatically shifts for fuel efficiency and convenience; S is the sport mode, providing more aggressive acceleration response, suitable for high-speed driving or overtaking; M is the manual mode, allowing manual upshifts and downshifts via paddle shifters or the gear lever for a more engaging driving experience. The correct shifting sequence is to engage P or N with the brake pedal before starting, shift to D or R when starting, and avoid engaging P while driving to prevent damage. The overall design combines the simplicity of automatic with the control of manual, making it quite suitable for long-distance driving and urban commuting.
As a novice driver, I've explored the automatic transmission with manual shift mode: Remember to use P (Park) when locking the car; engage R (Reverse) only after confirming it's safe; N (Neutral) is for temporary stops like traffic jams or red lights; D (Drive) is for normal forward movement with automatic gear shifting; S (Sport) mode is great for mountain driving, making the engine more responsive; M (Manual) mode feels like playing a game, allowing you to push the gear lever to adjust gears for more engagement. Beginners might make mistakes, like forgetting to shift to D when starting or incorrectly shifting to N, but with practice, major issues can be avoided. Protecting the transmission is paramount—avoid forcing gear changes while the car is moving, and regular fluid checks can extend its lifespan. Overall, it's easier to handle than a pure manual transmission, reducing the risk of stalling while still offering driving pleasure.
The manual-automatic transmission is quite practical: P (Park) locks to prevent rolling backward, suitable for temporary stops by the roadside; R (Reverse) assists in backing up; N (Neutral) for pushing the car or short idling; D (Drive) is the core for daily use, offering automatic convenience with less hassle; S and M modes enhance the driving experience—S (Sport) provides strong acceleration, while M (Manual) allows free control, combining the advantages of both for convenience without losing fun, making it a standard design in modern cars. In daily driving, D mode handles most situations without frequent gear changes.
