Can Automatic Transmission Cars Coast in Neutral Gear?
2 Answers
Automatic transmission cars should not coast in neutral gear. Detailed explanations are as follows: 1. Automatic transmission models cannot directly shift into N (Neutral) gear while driving in D (Drive) gear. The vehicle must come to a complete stop before shifting into N gear, making coasting in neutral gear impractical for automatic transmission vehicles. 2. The purpose of the neutral N setting in automatic transmissions is to meet parking needs in special circumstances or for towing purposes. When towing is required, the gear must be shifted into N because other gear positions are more likely to damage the transmission. The hazards of coasting in neutral gear include: 1. Loss of vehicle control, engine stalling, reduced braking effectiveness, increased braking distance, 2. Weakened power steering assistance, accelerated transmission wear, increased engine carbon buildup, 3. Increased fuel consumption, inability to obtain power immediately after descending a slope.
I've seen many people discussing this, thinking that coasting in neutral can save fuel or make driving smoother, but honestly, it's not a good idea. First, shifting an automatic transmission into neutral while driving disconnects the engine from the transmission, instantly losing engine braking. This means that when going downhill or slowing down, you can only rely on the brakes to stop the car, which can easily overheat, wear out, or even fail, significantly increasing the risk of accidents. I once had a friend who nearly lost control on a mountain road due to coasting. In neutral, the transmission lacks proper lubrication, the oil pump runs at a lower speed, and internal components are prone to wear—long-term damage can be costly to repair. I recommend staying in Drive (D) and letting the vehicle manage power transmission automatically—it's both safer and more reliable. Regular transmission maintenance is also crucial to prevent aging issues from affecting performance. If you're used to coasting, break the habit as soon as possible and have a professional inspect for potential hazards. In short, safety comes first; don't risk it for minor savings. Smooth driving is the way to go.
