For people driving automatic transmission system cars neutral shift is not something you use on a daily basis like the other gears, and when you do, it doesn’t seem very different from putting your car in park. Unlike the drive and reverse gears, neutral isn’t designed for use when driving the car. Neither is it like park, which is designed to keep the vehicle completely stationary.

Neutral gear separates the engine from the wheels. In automatic transmission, neutral is used when getting the car towed or physically pushed. Make no mistake in trying to shift to neutral when driving. This will damage the transmission system and will incur you expensive transmission replacement.

On the other hand in cars with manual transmission systems, neutral shift can actively be used and even for a long stretch of time. Similar to the automatic transmission, neutral disengages the engine from the wheels but this have a different effect when in use with manual cars. If you’re driving on a hilly terrain with no traffic, you can quite well put the car in neutral on top of each hill and just coast down to save fuel, and let the engine cool off without load. Neutral in manual cars can actually bring a car to a stop if it’s engages for a long time when driving.
