How to Use the N Gear in an Automatic Transmission?

[DeDaniela]

When waiting, make sure to shift the automatic transmission car to N gear. Use it for temporary parking. It's important to note: Although N gear indicates neutral, you still need to keep your foot on the brake to prevent the vehicle from rolling on a slope.

As a veteran taxi driver with ten years of experience, N gear is actually neutral, and its core function is to disconnect the engine from the wheels. When waiting at a red light for more than a minute, I shift to N gear and pull the handbrake. Doing this can reduce transmission wear, but don't coast downhill in N gear to save fuel—modern cars with electronic fuel injection won't save any fuel that way. When being towed, you must shift to N gear so the wheels can rotate freely; towing in P gear will destroy the transmission. Also, in automatic car wash conveyor belts, you need to shift to N gear to let the car move on its own. But remember, never coast in neutral—automatic transmissions are different from manuals, and coasting can cause insufficient transmission oil pressure, leading to part damage!
