What happens if you shift to P gear while driving?

[Luis]

Shifting to P gear while driving can cause severe damage or even total failure to the transmission. If you suddenly shift into P gear during normal driving, it will produce a series of very loud noises, which come from inside the transmission. While this doesn't cause significant damage to the engine and the car can still start and drive normally, it accelerates wear on the internal gears of the transmission. Generally, automatic transmission vehicles have gears P, R, N, D, and S. Here's an explanation of each gear while driving: 1. P is the parking gear, and the gear lever must be in P when the car is parked; 2. R is the reverse gear; 3. N is the neutral gear, which can be used when starting the car, parking without leaving the vehicle, or when towing; 4. D is the drive gear, and during normal driving, the gear lever should be in D, allowing the car to automatically shift between forward gears; 5. S gear is the car's sport mode, typically used for climbing hills and quickly overtaking.
