At what speed should you shift gears?

[Lloyd]

1st gear is used for starting; 2nd gear corresponds to a speed of 5-20km/h; 3rd gear corresponds to 20-40km/h; 4th gear corresponds to 40-60km/h; and 5th gear corresponds to 60-100km/h. Introduction to manual transmission: A vehicle that uses a manual shift mechanical transmission (also known as manual transmission, MT) to adjust speed. This means that the gearshift lever must be manually moved to change the gear meshing position inside the transmission, altering the gear ratio to achieve speed variation. The gearshift lever can only be moved when the clutch is depressed. Components of manual transmission: Gear shifting is achieved by switching different gear sets. As a key component in power distribution, the transmission must have two major parts: the power input shaft and the output shaft, along with the gears that make up the transmission, forming the most basic components of a manual transmission.

I've been driving manual transmission cars for many years, and I never memorize numbers for shifting gears; I mainly rely on the engine sound and the feel of the car. Generally, when the speed reaches around 15 km/h and the engine runs smoothly, I shift to 2nd gear. At 30 km/h, I shift to 3rd, at 45 km/h to 4th, and above 60 km/h, I engage 5th gear. But this varies from car to car; my sedan shifts comfortably into 5th at 55 km/h, while my friend's SUV needs 65 km/h to feel right. The key is to listen to the engine—don't let it roar too loudly. The optimal RPM is between 2000 and 3000. Shifting too early causes the car to shake and shudder, while shifting too late wastes fuel and harms the engine. On rainy days when the road is slippery, I downshift a bit earlier to increase traction, and the same goes for uphill driving. The more you drive and practice, the better you understand your car's behavior, leading to smoother and more fuel-efficient driving. Whenever I get a new car, I test-drive it at low speeds a few times to find the right shifting points before hitting the road. Don't just focus on the speedometer—pay attention to the overall driving feel, and always prioritize safety.

Shift gears smoothly and appropriately for safe driving. It is recommended to start in 1st gear at 0-15 km/h, shift to 2nd gear after accelerating to 20 km/h, switch to 3rd gear at 30-35 km/h, move to 4th gear at 50 km/h, and enter 5th gear around 60 km/h. Simultaneously, monitor the tachometer—shifting between 1500 and 2500 RPM is safest; shifting at too low RPM causes lugging and insufficient power, while shifting at too high RPM increases fuel consumption and wear risk. Reduce speed and downshift appropriately before curves to avoid losing control. Beginners should practice with lower gears in urban areas first, gradually increasing speed. Shift points vary by vehicle type, with compact cars shifting earlier than larger vehicles. For economical driving, shift to higher gears as early as possible to reduce fuel consumption. Stay calm overall and avoid rushing gear changes. Remember, if the engine sound becomes lighter or acceleration feels sluggish, check your gear position.

Gear Shifting Reference Speeds and Engine Status. Generally, 1st gear is used for 0-15 km/h, 2nd gear for 20-30 km/h, 3rd gear for 30-50 km/h, 4th gear for 50-70 km/h, and 5th gear for speeds above 70 km/h. A more accurate method is to observe the tachometer; shifting around 2400 RPM ensures the smoothest transition. Delay shifting when the engine is under heavy load, such as downshifting to increase power when climbing hills. Shift earlier on flat roads with a light load to save fuel. Automatic transmissions adjust automatically, while manual transmissions require practice to develop a feel. As long as the engine isn't roaring, it's fine.
