What is the method of shifting gears without depressing the clutch?

The method of shifting gears without depressing the clutch is: 1. For upshifting, the sequence is to release the throttle, disengage the gear, wait for the engine speed to drop, and then engage the higher gear; 2. For downshifting, the sequence is to release the throttle, disengage the gear, rev the throttle to increase the engine speed, and then engage the lower gear. The working principle of the clutch is: 1. When the inner race is fixed, the outer race rotates clockwise and the wedge does not lock, allowing the outer race to rotate freely; 2. When the outer race rotates counterclockwise, the wedge locks, preventing the outer race from rotating. The functions of the clutch include: 1. Gradually increasing the driving force of the car to ensure a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration and shock from the engine, thereby extending the lifespan of the transmission gears.
I've been driving manual transmission cars for several years. Shifting without using the clutch sounds cool, but you need to be careful. It mainly involves the technique of RPM matching. For example, when upshifting, accelerate to a certain speed, release the throttle momentarily to shift, allowing the engine RPM to synchronize with the transmission gears. The same goes for downshifting - reduce speed and push into a lower gear after the RPM drops. However, this really isn't suitable for beginners as it can easily cause gear grinding and damage the car. I only try it on racetracks or in emergencies. It's best to normally use the clutch to protect the transmission, as repairs can be very expensive. Also remember that driving manual requires anticipation, and maintaining smooth operation can extend component lifespan.
As a veteran driver with over a decade of manual transmission experience, I occasionally use clutchless shifting, especially in emergencies like clutch failure during traffic jams. The technique involves starting in second gear, accelerating, then gently shifting when the RPM feels right without forcing it to prevent damage. Honestly, it's risky—I wrecked a gearbox in my younger days, costing thousands to repair. So now I avoid it unless absolutely necessary. Manuals are fun but wear faster, requiring diligent maintenance. For daily driving, using the clutch is safer, especially on slippery rainy roads where risks aren't worth taking.
