Is it possible to coast in neutral (N) gear with an automatic transmission car?
1 Answers
Automatic transmission cars should not be shifted into neutral (N) gear for coasting, as coasting in neutral can cause significant harm to the automatic transmission. The automatic transmission requires lubrication, and when the gear is placed in N while driving, the oil pump cannot supply oil normally for lubrication, which will cause the internal components of the transmission to heat up and result in damage. Effects of coasting in neutral with an automatic transmission car: When the vehicle is moving at high speed, both the engine speed and the output shaft speed of the automatic transmission will be very high. Once the gear is shifted to N, the connection between the engine and the wheels will be lost, and the hydraulic lines inside the automatic transmission will experience insufficient oil pressure, preventing normal lubrication of the transmission. This will lead to an increase in the internal operating temperature of the transmission, increasing friction pressure, and also damaging the friction plates inside the transmission. Over time, the internal components of the transmission will age prematurely, and in severe cases, the transmission may be completely ruined. An automatic transmission, as the name suggests, does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. Automatic transmissions have corresponding gears, and whether manual or automatic, the more gears there are, the more fuel-efficient the vehicle will be. For short stops, such as at a brief traffic light, simply pressing the brake is sufficient. If the stop lasts more than 2 minutes, it is advisable to shift into N gear to protect the transmission and prevent the transmission fluid from overheating.
