What are the speed ranges for 1st, 2nd, 3rd, and 4th gears in a manual transmission?
1 Answers
1st gear is for starting, with a speed range of 0-5 km/h; 2nd gear corresponds to 5-20 km/h; 3rd gear corresponds to 20-40 km/h; 4th gear corresponds to 40-60 km/h; and 5th gear corresponds to 60-100 km/h. Generally, the ideal time to shift gears is when the engine speed reaches 2000 rpm, preferably not exceeding 2500 rpm. Below is additional information on gear shifting: Upshift timing: When the engine has ample power, it emits a dull humming sound. If, after upshifting, there is no power deficiency or shaking of the transmission mechanism, and the vehicle accelerates quickly and runs smoothly, it indicates accurate upshift timing. Downshift timing: When the vehicle's speed and engine rpm continue to drop, and you feel the car losing power with the engine compartment starting to shake, it's time to downshift one gear. Downshifting too early will cause noticeable jerking, wasting engine power, increasing fuel consumption, and negatively impacting the lifespan of the engine and transmission. Downshifting too late will result in insufficient power even after downshifting, and continued downshifting will still feel jerky. Misjudging the shift timing can lead to such irreversible consequences, inevitably affecting the driving experience.
