Manual transmission gears and their corresponding speed ranges are as follows: 1st gear for 015km/h, 2nd gear for 1025km/h, etc. Below is the detailed introduction to gear speeds: Speed ranges for each gear in a manual transmission car: 1st gear corresponds to a speed range of 015km/h. 2nd gear corresponds to 1025km/h. 3rd gear corresponds to 2045km/h. 4th gear corresponds to 4060km/h. 5th gear corresponds to >60km/h. These are merely theoretical speeds, as the vehicle's speed, engine RPM, and gear position are inherently related, so gear shifting shouldn't be based solely on speed. Applicable situations for each gear: 1st gear is the starting gear, used when initiating the vehicle. Its gear ratio is similar to reverse gear, with comparable performance, hence not suitable for prolonged high-speed operation. Generally, shift to 2nd gear once the vehicle gains momentum. 2nd gear is the passing gear, mainly used for navigating complex road conditions and handling difficult situations, such as sharp-angle (right-angle) turns without special obstacles, crowded urban areas, steep slopes, and bumpy roads. 3rd gear is the transition gear, primarily for low-speed urban driving; depending on circumstances, it allows easy acceleration to 4th gear or deceleration to 2nd gear. 4th gear is the cruising gear, mainly for prolonged high-speed and economical driving, with most vehicles achieving optimal fuel efficiency at lower speeds in this gear. 5th gear is the high-speed gear, mainly used for long-distance highway driving.

A veteran driver with 20 years of experience tells you that shifting gears in a manual transmission isn't about memorizing speed numbers—it's all about listening to the engine. Start in first gear until around 15 km/h, then shift to second if the car isn't shaking; cruise in second until about 25 mph, then smoothly shift to third when the throttle feels right. Third gear feels most comfortable between 35-40 km/h, while fourth gear at 45-55 is the most fuel-efficient for cruising. Fifth gear is for 60 and above—go wild. In traffic, I often stay in second to avoid frequent gear changes. On steep slopes, it's better to keep the revs high in a lower gear than to let the engine struggle—that painful growl hurts to hear. Remember, the speedometer is just a reference—every car has its own personality. Once you're familiar, you'll know when to shift just by the feel of your heel.

During the last maintenance, the technician reminded me that incorrect gear shifting timing can severely damage the clutch plates. Holding first gear beyond 20 km/h can easily overheat the plates, while forcing acceleration in fifth gear below 50 km/h can cause engine carbon buildup. Their repair shop currently has a car with a blown gearbox from driving 40 km/h in second gear. The ideal shift point is around 2000 RPM. For a 1.6L engine like mine: first gear 0-15 km/h, second gear 15-30 km/h, third gear 30-50 km/h, fourth gear 50-70 km/h, fifth gear 70+ km/h. You can delay upshifting during rapid acceleration, but avoid letting the tachometer enter the red zone - it sounds like shaking screws in a tin can.

Right after getting my driver's license, the instructor kept yelling 'watch the tachometer, not the road'. Now I understand the essence of manual transmission lies in the coordination of clutch and throttle. Start in first gear and shift to second as soon as the car moves, around 15 km/h; accelerating to 25 km/h in second gear makes the shift to third smoothest; third gear delivers the strongest power between 35-45 km/h; cruising at 60 km/h in fourth gear on highways is very stable, while downshifting to third gives more power for overtaking. Remember not to drive at low speeds in high gears during rain - it causes the exhaust to pop and wastes fuel.
