What are the techniques for shifting gears without depressing the clutch in a car?

There are two main techniques for shifting gears without depressing the clutch in a car. Below is a detailed introduction to these two techniques: 1. Try to increase the engine speed before shifting: When the vehicle speed is high, the transmission gear speed is slightly higher than the engine speed, and the transmission's driving gear and driven gear are in a "meshing" state. At this time, it is possible to shift gears without depressing the clutch. 2. Quickly move the gear lever to a higher gear: When the engine speed and transmission speed are exactly the same, the gear lever can be switched to a higher gear. Meanwhile, shifting without depressing the clutch consumes more fuel, but the shifting speed is faster, and the vehicle has more power.
I've been driving for over twenty years, and once when the clutch suddenly failed, I had to shift gears by matching the engine speed. The specific method is: before shifting, observe the vehicle speed. For example, when shifting from first to second gear, first release the throttle to stabilize the speed, wait for the RPM to drop to around 2000, then gently push the gear lever. Downshifting is the opposite; you need to slightly press the accelerator to raise the RPM to around 3000 to match the speed before shifting. This requires repeated practice to get the feel, and the action must be quick and gentle—no forceful pushing, otherwise it can cause gear grinding and damage the transmission. I recommend using this method only in emergencies, such as when the clutch completely fails and you need to move the vehicle. Under normal circumstances, always develop the good habit of using the clutch properly. If any issues arise, promptly seek a professional repair shop to inspect and fix the clutch system—safety comes first.
