Does coasting in neutral affect the transmission of an automatic car?

[McDaniela]

Coasting in neutral does affect the transmission of an automatic car. The reasons are: 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 of components such as the hydraulic directional valve and planetary gears; 2. It generates a large amount of heat, leading to oil carbonization and sludge formation, which can block oil passages and result in insufficient oil supply and poor lubrication after normal operation. The gear positions of an automatic car are: 1. P (Park) position is for parking and starting; 2. R (Reverse) position is for reversing; 3. N (Neutral) position is for neutral; 4. D (Drive) position is for forward movement, also known as the driving gear; 5. S (Sport) position is for sport mode; 6. L (Low) position is for low speed.
