Automatic transmission cars require pressing the brake when shifting gears, while manual transmission cars need to press the brake when downshifting from a higher gear to a lower gear if the speed is too high, to control the speed before shifting. Upshifting from a lower gear does not require pressing the brake. Automatic transmission cars must press the brake when shifting gears: For safety reasons, automatic transmissions have a torque converter or automatic clutch. Once the power is engaged, the car immediately moves forward or backward. Since there is no manual clutch process and the engine won't stall, the car's movement can only be controlled by the brake. Given that the brake and accelerator are on the same side, the foot is either on the brake or the accelerator. The system is designed to require pressing the brake to shift gears primarily to prevent the foot from being on the accelerator and to control the car's speed. Manual transmission cars have more gears, ranging from 1st to 6th, all requiring manual shifting. Therefore, when shifting in the same direction, only the clutch needs to be pressed to shift gears. However, if shifting from a forward gear to reverse, the brake must be pressed first to bring the car to a complete stop before shifting into reverse. When downshifting from a higher gear to a lower gear, if the speed is too high, the brake must be pressed to control the speed before shifting, otherwise, the gearbox may be damaged. Upshifting from a lower gear does not require pressing the brake.

Having driven a manual transmission car for many years, I can tell you that you don't need to press the brake every time you shift gears. If you're driving a manual, like my old Santana, shifting relies mainly on the clutch pedal to control speed matching. Braking is only necessary in specific situations, such as stopping or preparing to start/stop. However, it's different with automatic transmission cars—you generally need to press the brake every time you shift. This is a safety design to prevent accidentally engaging reverse or drive gears, which could cause unintended rolling. Some newer cars even have electronic shifting systems with stricter operation requirements. Overall, the type of car matters most: manuals offer flexibility but require more practice with clutch control, while developing the habit of braking in automatics can protect the transmission's lifespan. For beginners who are unsure, I recommend checking the owner's manual first to avoid developing bad habits that could harm the car.

Back when I was learning to drive, my instructor emphasized that with an automatic transmission, you basically need to step on the brake every time you shift gears, otherwise the car won't move at all. Take my little Fit for example—it's designed this way; you must brake before shifting to D or R to prevent accidents caused by misoperation. Manual transmission cars offer more freedom when shifting, like moving from a lower gear to a higher one—just match the throttle, no need to brake. However, for safety when parking, it's still best to brake first. At first, I often forgot to brake, leaving the car stuck in place, but later I developed good habits and it became much smoother. Beginners should practice with a reliable car to get used to different transmission characteristics—don't worry about the hassle.

As a mom who frequently shuttles kids to and from school, I always press the brake when shifting gears in an automatic car—it's become second nature. Why? Safety first. Automatic cars are designed to require braking before gear shifts to prevent sudden acceleration from mis-shifting. Manual transmissions allow gear changes while moving, like adjusting gears during a slow coast. But I always remind my husband not to be careless—ensuring the car is fully stopped before shifting reduces wear risks. Simply put, whether to brake depends on the car type: automatics are stricter.

As a car enthusiast, I believe whether to step on the brake when shifting gears depends on the transmission type. Manual transmissions offer more freedom, relying on clutch and throttle coordination for gear changes, with braking only necessary when stopping. Automatic transmissions are different—shifting requires braking, or the vehicle's safety system will lock. Having modified cars, I understand the principle: automatic transmissions have interlock mechanisms to prevent misoperation. In fact, different models like CVT or DSG have similar requirements. The key is to know your car well and not force the system limits.
