Is It a Malfunction When There's a Strange Noise While Shifting to P Gear?
2 Answers
There are two scenarios when a strange noise occurs while shifting to P gear. If you park on a slope and shift to P gear before pulling the handbrake, a clunking sound is considered normal. However, if you shift gears before the car comes to a complete stop, the clunking sound can significantly shorten the transmission's lifespan. Detailed information about gear positions is as follows: 1. Automatic transmissions have P-R-N-D-M gear positions. Except for R-N-M, which are for forward and reverse driving, both N and P are used when parking to cut off the power source. N gear is neutral parking, and you still need to engage the handbrake to prevent the car from rolling. P gear not only cuts off the power source but also prevents the car from rolling. 2. If you shift to P gear while the car is moving, at best, it can cause severe wear on the transmission gears or produce strange noises; at worst, it can damage or even destroy the transmission and drivetrain components.
Having driven for over a decade, I can say that occasional slight noises when shifting into P gear are actually quite common. This sound is usually the click from the transmission locking mechanism engaging, which is a normal mechanical operation sound. However, it's important to distinguish the type of abnormal noise: if every gear shift is accompanied by a harsh metal grinding sound or if the gear lever feels noticeably stiff, then it warrants attention. This situation might indicate issues like a stuck locking pin, deformed mechanism, or abnormal transmission fluid level. It's advisable to follow the correct parking sequence: engage the handbrake first before shifting to P gear, as this can reduce pressure on the locking mechanism. If still concerned, it's best to visit a repair shop and have a mechanic listen to the sound—transmission issues are not to be taken lightly.
