Should an automatic transmission start in P gear or N gear?

[MacCayden]

Many automatic transmission cars start directly in P gear, and it is not possible to start in N gear. The N gear and P gear of the vehicle's automatic transmission can basically be used when parking, but there is a difference between N gear and P gear. The N gear does not have a locking mechanism. When the N gear is engaged without pulling the handbrake, the vehicle can move. The P gear has a locking mechanism. When the P gear is engaged, the locking mechanism locks the gear of the transmission, which is equivalent to indirectly locking the wheels. At this time, the vehicle cannot move without pulling the handbrake. Correct habit: Before shifting into P gear, you must ensure that the vehicle is completely stopped, otherwise it will damage the locking mechanism of the P gear. When driving an automatic transmission car, you should not shift into N gear to coast, as this will affect the lubrication and heat dissipation of the automatic transmission. If you coast in N gear for a long time and over a long distance, it may immediately cause the automatic transmission to burn out. In daily use, it is necessary to maintain good usage habits, as good usage habits can extend the service life of the vehicle.
