Do You Need to Press the Brake for Automatic Transmission Gear Shifting?

[Rex]

Automatic transmission cars require pressing the brake when shifting gears; failing to do so can damage the automatic transmission. When driving, shifting from D to D3 or D2 does not require pressing the brake. However, if you suddenly shift from D to a lower gear at high speed, the engine RPM will become very high, and the car body will experience significant jerking. When driving at low speeds, you can directly shift to a lower gear. Some cars also have S or M modes, which can be switched to from D mode while driving. Additional Information: 1. D Mode Gear Shifting: When preparing to start driving, after pressing the brake, push the gear lever forward to D mode, then fully release the handbrake, gently press the accelerator, and after the car moves forward a certain distance, release the brake and continue pressing the accelerator. At this point, the car will automatically shift between gears 1 to 4 based on speed. Under normal driving conditions on flat roads, the driver does not need to shift to other gears. 2. When going downhill for a long distance, since the D mode of an automatic transmission car does not have engine braking functionality, do not keep it in D mode. Otherwise, the speed will keep increasing, posing safety risks, and frequent braking will cause the brake pads to overheat and wear excessively. P Mode Parking Gear Shifting: When the vehicle needs to be parked for a long time, especially on a slope, shift to P mode. In this mode, the wheels are mechanically locked, ensuring the vehicle cannot move while stationary. 3. It is important to note that you should shift to P mode after turning off the engine and then remove the key. Shifting to P mode before turning off the engine can damage the transmission gears. Never shift to P mode while the vehicle is moving, as this can cause severe damage to the vehicle.
