What happens if you shift into P gear while driving?

[Silas]

Although the P gear can be used to achieve braking effect when the car's braking system fails, suddenly shifting into P gear during normal driving will produce a series of very loud noises, which come from inside the transmission. Of course, this does not cause significant damage to the engine, and the car can still start and drive normally, but it will accelerate the wear of the internal gears in the transmission. Here is some additional information: 1. In fact, the P gear functions similarly to N (neutral gear plus handbrake) and can replace the vehicle's braking system when the handbrake fails, preventing the car from rolling. 2. Of course, do not use the P gear for braking at high speeds unless in an emergency, as it will cause significant impact on the transmission. In such cases, the pawl and ratchet wheel may deform due to high-speed collision, and the pawl may even break. The broken parts moving inside the transmission can cause irreversible damage or even render the transmission completely unusable.
