What is the speed for shifting from second gear to third gear?
3 Answers
The speed for shifting from second gear to third gear is 20km/h. Relevant information about gear shifting in cars is as follows: 1. Gear speed range: 0 to 10km/h is within the first gear range; 10-20km/h is within the second gear range; 20-30km/h is within the third gear range; 30-40km/h is within the fourth gear range; 50km/h is the upper limit within the fifth gear range. 2. Gear shifting notes: When shifting gears, the clutch and throttle must be well-coordinated. Depress the clutch fully and immediately release the throttle pedal, then quickly shift to the corresponding gear. After shifting, release your hand immediately and do not keep it on the gear lever for a long time, as this can easily damage the gear lever.
Shifting speed isn't a fixed thing—it really depends on what car you're driving and personal habits. I drive a compact sedan, and when shifting from second to third gear, I usually do it around 2000 RPM, with the speed between 20 to 30 km/h. Shifting too early makes the engine shudder, like it's running on an empty stomach; shifting too late makes the engine roar loudly, wasting fuel. When I first learned manual transmission, my instructor said to listen to the engine—if it sounds smooth, it's fine. Road conditions also make a big difference—on uphill slopes, you should shift later to avoid losing RPM and struggling to pull the car. In short, practice a few times, and the feel will come naturally—don't just stare at the speedometer and memorize numbers. Once you get familiar, you'll find the rhythm smoother, the car more fuel-efficient, and engine wear reduced.
As a frequent driver of manual transmissions, I've found the ideal speed range for shifting from second to third gear is between 25 to 40 km/h, with the key factor being the engine's torque curve. The engine delivers peak power between 2500 to 3000 RPM - that's the sweet spot for upshifting to third gear. In my old Japanese car, I typically shift around 2000 RPM at approximately 25 km/h; but when driving my friend's high-performance vehicle, I'll rev it up to 3000 RPM at 35 km/h before shifting for smoother power delivery. Vehicle type matters too - smaller engines benefit from earlier shifts for fuel efficiency, while SUVs or loaded vehicles need delayed shifts to maintain momentum. Never rely solely on speed - the golden rule is avoiding engine lugging or over-revving to prevent blown fuses. Developing the habit of monitoring your tachometer will significantly extend transmission lifespan.
