Despite their fast growth, automatic gearboxes are not being adequately utilized by many drivers despite their adaptability and convenience.

The function of the neutral gear in an automated vehicle is frequently questioned. A neutral regime may be necessary, but it is not apparent why or how it should be used.

What is the role of neutral gear in an automatic transmission?

What Is Neutral In A Car

Only extreme circumstances necessitate the usage of the neutral gear. A neutral mode in an automatic gearbox means that the engine and wheels are no longer communicating, so no torque is sent to the driving axle. You should use the neutral (N) in an automatic car when it is damaged and cannot move without being towed.

As a result, the car will not be subjected to an increased amount of stress, which could lead to overheating. While in neutral mode, the input power shaft is totally blocked, but the output power shaft remains free, allowing the wheels to rotate freely and thereby towing the vehicle.

Some auto enthusiasts and mechanics feel that towing speeds should not exceed 30 kilometers per hour (19 miles per hour), while others advocate for towing speeds of up to 50 kilometers per hour (31 miles per hour) (31 miles per hour).

An automatic gearbox vehicle’s towing capacity is not built for long-distance driving. Towing your vehicle to the first workshop is recommended if it is a considerable distance.

When the wheels need to be unlocked before repair, the selector can be switched to neutral, and the engine can be started while the car is still parked by pressing the brake pedal or activating the parking brake.

When does the use of neutral gear in an automatic transmission affect your car?

What Is Neutral In A Car-2

Using neutral in an AT can have a negative impact on your vehicle. The N (neutral) position on the shifter is incorrectly used by some drivers when parking in parking lots; this is dangerous.

Because the wheels aren’t blocked when the parking brake is engaged, the car will roll if you don’t remember to apply it, potentially resulting in an accident. As a result, parking mode (P) rather than neutral should be selected the majority of the time.

Another instance in which the neutral gear in an automatic car should never be used is when coasting or traveling down a sloped road. As a result of this, if the car’s selector is shifted to neutral mode while the driver is behind the wheel, the unit will not receive sufficient oil and will be forced to rotate without it.

A lack of lubricant speeds up the wear of the automatic transmission’s rubbing elements, which are lubricated by transmission oil throughout operation. There is friction, heat, wear and failure when surfaces come into contact.

Constant traffic-light delays also fall under this category. The clutches open and close, and the shafts are separated, if you move the lever to the neutral position N. When the traffic lights turn green, the driver shifts into gear D again, but he does so after only a few minutes of driving.

As a result of the frequent switching between modes, the transmission will quickly fail.

Driving with the automatic transmission engaged (D) and pressing and holding the brake pedal when approaching a red light is the safest option. When the transmission is in D mode, the torque converter maintains its pressure and the transmission components are well lubricated.

If you have an automatic transmission, you can avoid numerous gear changes by keeping the shift lever in the D position. You can, however, engage the P gear and turn off the motor if the traffic bottlenecks are particularly long.


Unlike manual transmissions, where the neutral position is utilized frequently, the neutral position in an automatic car is used only when necessary, such as when towing. It is against the law to shift into neutral while driving, and doing so on many vehicles is just impossible.
