Can Automatic Transmission Cars Coast in Neutral Gear?

[VanReagan]

Automatic transmission cars should not coast in neutral gear for the following reasons: 1. When idling, the engine's oil pressure output is low, resulting in insufficient lubrication supply, which can easily cause poor lubrication and severe wear to components such as hydraulic directional valves and planetary gears; 2. It generates a large amount of heat, leading to oil carbonization and sludge formation that can clog oil passages, resulting in insufficient oil supply and poor lubrication during normal operation. Automatic transmissions eliminate the need for drivers to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. The gear positions are as follows: 1. P stands for Parking gear; 2. R stands for Reverse gear; 3. N stands for Neutral gear; 4. D stands for Drive gear; 5. S stands for Sport mode; 6. L stands for Low gear.
