What is the correct operation method for downshifting with throttle blip?

The correct operation method for downshifting with throttle blip is: depress the clutch and shift to neutral, release the clutch and blip the throttle, depress the clutch and release the throttle while shifting to a lower gear, then release the clutch and press the throttle to move forward. During the downshifting with throttle blip process, you need to depress and release the clutch twice and press the throttle twice, which is known as the double-clutch throttle blip method. Downshifting with throttle blip is used when the car needs to downshift to synchronize the gear teeth and avoid damage caused by excessive speed difference forcing the synchronizer sleeve to engage. When the car is idling, shift gears without pressing the throttle. After shifting gears, releasing the clutch will cause the engine to rotate due to the car's inertia. However, when the clutch is released, a jerking sensation will occur due to the mismatch between the engine speed and the vehicle speed. This jerking sensation becomes more pronounced as the engine speed increases during gear shifting.
I've been driving manual transmission for over 20 years, and rev-matching is an essential skill to master. When you want to downshift for overtaking or slowing down, press the clutch, shift out of gear, then lightly tap the throttle with your right foot to raise the RPM slightly to match the next lower gear's speed. Then engage the lower gear and release the clutch. You need to practice this until it becomes second nature, otherwise the car will jerk and the engine might make clunking sounds. When I was learning, I often messed up, making the car jerk repeatedly, which accelerated transmission wear over time. Now, every downshift is smooth, keeping the car stable and protecting the engine. Remember not to stomp on the throttle—just a gentle tap is enough. This technique is especially useful on highways or mountain roads for quick response to changing conditions. Find an empty road to practice slowly a few times—it's not just about driving pleasure but also a safety habit.
When I first bought my car, I knew nothing about rev-matching downshifts. Later, a friend taught me the trick. Simply put, for example, when downshifting from fifth to fourth gear, first press the clutch, shift out of gear, quickly tap the throttle to raise the engine RPM, and when the RPM approaches the target gear, engage the gear and release the clutch. The key is to match the RPM accurately—don’t rush it. I can feel the car becoming smoother with much less shaking. It’s useful in daily traffic jams or on slopes, making things much easier. Once mastered, it boosts driving confidence and reduces clutch wear. I recommend beginners start practicing at lower speeds, like under 40 km/h in the city, observing the tachometer changes. The benefit is smoother driving and more efficient engine operation. Never rush—just lightly tap the throttle at 20-30% is enough.
