Is It Normal for the Gear Lever to Make Noise When Braking in P Gear?

Normal. This is the operation of the transmission gear lock solenoid valve. When the brake is not pressed, it is in a locked state. When the brake is pressed, it unlocks, resulting in the sound of the solenoid valve. Below are specific reasons for abnormal noises when braking in a car: 1. Improper installation of brake pads: When installing new brake pads, if the old brake disc is not polished, it can lead to improper fit. Improper installation or installing new brake pads without polishing the old disc can cause the new pads to rub directly against the uneven surface of the old disc, eventually leading to uneven wear of the new brake pads. 2. Brake system malfunction: There may be defects in the brake system itself, causing the brake pads to only partially contact the brake disc. This increases the pressure per unit area on the brakes, resulting in abnormal noises. It is recommended to check components such as the caliper and guide pins. 3. Presence of foreign objects: Foreign objects can cause the contact surfaces to not fit properly, leading to abnormal noises.

I've been driving automatic transmission cars for many years, and often encounter friends asking if the strange noise when pressing the brake in P gear is a problem. Actually, in automatic transmission vehicles, this is usually normal because pressing the brake triggers the gear shift lock release mechanism, allowing you to shift from P gear to other gears. That slight clicking sound is the solenoid or linkage in action, similar to the sound of a switch turning. However, if you hear continuous squeaking or particularly harsh noises, you should pay attention, as it might be due to insufficient lubrication of the lock mechanism, component wear, or loose wiring. I suggest you ask the technician to check the gear module during your next maintenance to ensure there are no safety hazards. After all, safety comes first, and paying more attention to these small details while driving can help avoid major issues.

I was also worried about this in the first year of owning my car, thinking it was broken. Actually, a small sound when pressing the brake in P gear is quite common, and many cars have this. I consulted a car-savvy friend who explained that it's the unlocking mechanism at work, designed to prevent accidental gear shifts. If it operates smoothly, there's no need to panic; but if the sound gets louder or is accompanied by vibration, it might be due to spring aging or dust buildup, which requires cleaning. During regular maintenance, don't just focus on engine oil and tires—don't overlook the gear lever components either. Simply put, small noises are normal, but significant ones need attention.

I think it's no big deal when there's noise from pressing the brake in P gear while driving. Many automatic vehicles have similar designs, where the sound comes from the brake triggering the lock release system. As long as it's not a loud noise or abnormal sound persists, you can use it with confidence in daily driving. But for safety's sake, just regularly check and lubricate the locking mechanism.
