What are the speed ranges for 1st, 2nd, 3rd, and 4th gears in a manual transmission?

[VonIker]

Manual transmission gear speed ranges are as follows: 1. 1st gear: Speed range is 0 to 5 kilometers per hour; 2. 2nd gear: Speed range is 5 to 20 kilometers per hour; 3. 3rd gear: Speed range is 20 to 40 kilometers per hour; 4. 4th gear: Speed range is 40 to 60 kilometers per hour; Gear shifting timing: When the engine has sufficient power, it will emit a dull humming sound; Downshifting timing: When you feel the car lacks power or the engine compartment starts to vibrate, downshift one gear. Downshifting too early will cause noticeable jerking, while downshifting too late will result in insufficient power.
