Is it necessary to press the clutch when shifting gears while driving?

Manual transmission vehicles require pressing the clutch when shifting gears, while automatic transmission vehicles do not. The clutch is located within the flywheel housing between the engine and the transmission, with the clutch assembly secured to the rear plane of the flywheel by screws. The output shaft of the clutch serves as the input shaft of the transmission. The primary technical indicators and techniques for ensuring smooth gear shifting involve synchronizing the two meshing gears during shifting, allowing the gear sleeve to smoothly engage both transmission gears at the moment of synchronization. When the clutch is depressed, the engine's drive mechanism disconnects from the wheels, preventing engine power from being transmitted to the wheels and thus not driving the car. When the clutch is released, the engine's drive mechanism reconnects with the wheels, transmitting power to the wheels and enabling the car to move.
I've been driving manual transmission cars for many years, and it's essential to depress the clutch when shifting gears; otherwise, the transmission can easily be damaged. The clutch serves to disconnect the engine's power, allowing the gears to engage smoothly. Skipping this step and forcing a gear shift can lead to gear grinding or wear, producing a distressing crunching sound. Although some attempt to shift without the clutch by precisely matching engine speeds at high velocities, this requires exceptional skill and is only suitable for professional racing or vehicles with particularly good synchronizers. Doing this in everyday driving carries significant risks. Developing the habit of using the clutch can reduce maintenance needs and make driving smoother and safer. Every time I drive, I remind myself not to cut corners—this small action protects the entire drivetrain and extends the vehicle's lifespan.
Shifting gears definitely requires stepping on the clutch pedal—that's how manual transmissions work. Pressing the clutch pedal disconnects the engine from the gearbox, ensuring smooth and resistance-free gear changes. As someone who studies cars and frequently tests various driving techniques, I can confirm that clutchless shifting, while it sounds cool, is extremely difficult to execute successfully. It only works under specific conditions, such as when the engine RPM matches the gear synchronization point. Otherwise, it can damage the synchronizer or cause abnormal noises, leading to costly repairs. From a safety perspective, using the clutch prevents accidental gear jamming or loss of control. Remember to practice clutch pedal pressure on flat roads to make each gear shift feel natural and comfortable.
As an ordinary driver, I always press the clutch when shifting gears in a manual car. This basic operation prevents sudden impacts on the transmission and protects the gear structure. Not pressing it may cause vibrations or damage due to mismatched force transmission, and no one recommends doing this in daily driving. Although it's technically possible to achieve clutchless shifting through precise RPM control, that requires repeated practice and is prone to errors, making it unnecessary to take the risk. Developing good driving habits makes for a more worry-free and safer experience. Vehicle maintenance also becomes simpler, with the clutch lasting longer, saving both repair time and money.
