What is the introduction to manual transmission gears?

Manual transmission gear introduction: 1st gear is mainly used for normal vehicle starting or climbing, with the entire speed maintained at 10km/h; 2nd gear is mainly used for low-speed forward movement or climbing steep slopes, with the speed maintained at 20km/h; 3rd gear is mainly suitable for driving on urban roads, with speeds ranging from 20 to 40km/h; 4th gear has a speed of 40 to 60km/h; 5th gear has a speed above 60km/h; N gear is neutral; R gear is reverse. Manual transmission is a manual gearbox, also known as manual transmission, which requires manually shifting the gear lever to change the gear meshing device inside the transmission, altering the gear ratio to achieve the purpose of shifting. The working principle of manual transmission: By using the shift fork to change the gear ratio of the meshing gears, the driving torque is altered to suit different working conditions.
The gear introduction for manual transmission is quite straightforward. Having driven a manual for years, the gear stick typically has R for reverse, N for neutral, and 1 to 6 for forward gears. Use 1st gear when starting; the car has power but moves slowly. 2nd gear is ideal for accelerating between 20-30 km/h; 3rd gear provides smooth driving at 30-40 km/h; 4th gear speeds up to 40-50 km/h; 5th gear is fuel-efficient at high speeds; if there's a 6th gear, overtaking becomes easier. Lower gears offer greater torque when climbing hills or carrying loads, preventing stalling. Manual transmission requires shifting gears yourself—while challenging for beginners, once accustomed, it offers a sense of precise control. Each gear shift feels like a conversation with the car, and fuel consumption is usually about 10% lower than automatic transmissions. Remember to shift to neutral at traffic lights to save effort, and long-term use can extend the transmission's lifespan.
When learning to drive, the instructor always emphasizes the importance of manual transmission gears: R is for reverse, N is for neutral parking; use 1st gear for starting, applying force ensures a stable start; 2nd gear is for accelerating in the city after starting; 3rd gear is for climbing hills or speeding up on fast roads; 4th gear provides smoother cruising above 40 km/h; 5th gear saves fuel at 60 km/h. Initially, I was all thumbs with the manual transmission, but with practice, I mastered the timing—avoid high gears at low speeds to prevent engine roaring, and don’t use low gears at high speeds to avoid wearing out the car. Once you get the hang of it, manual transmission is more exhilarating than automatic, especially when shifting gears on winding mountain roads—it’s incredibly agile. It also automatically fine-tunes power to protect the engine based on load, resulting in much lower fuel consumption. I recommend beginners start with a simulator for safety.
As a mechanic by trade, the essence of manual transmission gears lies in gear coordination: R for reverse, N to disconnect power; 1st gear provides strong torque for starting, ideal for slopes; 2nd gear serves as transitional acceleration; 3rd gear suits urban cruising; 4th gear enables fuel-efficient driving; higher gears enhance speed. Common issues during repairs include incorrect gear selection—low speed with high gear causes engine knocking, while high speed with low gear accelerates gear wear. Daily driving at appropriate shift points (e.g., 20 km/h for 2nd gear, 40 km/h for 4th gear) maintains transmission longevity. Manual transmissions feature simple structures with low maintenance costs, sharpen driver focus to prevent accidents, and reduce skidding risks in rain/snow when using lower gears.
