Isn t it harmful to the car if the car is not in automatic transmission?

The automatic transmission car must not be attached to the n gear to slide, because the automatic transmission needs to be lubricated, when the gear is placed on the n during the driving oil pump is unable to supply oil normally for lubrication, the temperature of the internal parts of the transmission will rise, and the transmission will be damaged. In addition, coasting in neutral at high speeds downhill is also very dangerous and not fuel-efficient. However, sliding to a stop at low speed can be put into N gear in advance, which has no effect.

It is also important to note that if the vehicle breaks down while driving and needs to be towed by the vehicle, the gear must be placed in neutral. Both the P and N gears are used to deactivate the engine and wheel drivetrain.

The difference is that when the engine stops running, the vehicle can be pushed at will by holding N gear. When the P gear is engaged, the transmission shaft is locked to the transmission housing by a mechanical locking pin. Therefore, if the vehicle is forcibly dragged down in the P gear state, it will inevitably cause damage to the automatic transmission shell, resulting in heavy losses; At the same time, when parking uphill and downhill, do not only use the P gear brake vehicle, but should firmly tighten the hand brake, so as not to make the P gear mechanical lock too stressed and damaged.

Generally, the towing speed should not exceed 30 km h, and the total driving distance should not exceed 50 km, so as to avoid damage to the transmission caused by lack of oil.

Hello! If you coast in neutral with manual gear, it will have no effect on the car, but from the perspective of safe driving, it is not allowed! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello If you don't have a gear, it doesn't have any effect, and the manual transmission can coast in neutral. I hope it can help you and I wish you a happy car. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Cars with automatic transmissions are not allowed to be in neutral while driving.

1. When the automatic transmission car is in neutral gear during driving, the braking force of the car will decrease, which is easy to cause rear-end accidents.

Because the car is coasting in neutral gear, the engine and the drive wheels will lose contact, and the car will rely on its own inertia to move forward. Then, in the event of an emergency that requires braking, the full braking force can only be provided by the brakes. When coasting in gear, the engine itself will provide a certain amount of pulling, and with the braking, the braking distance of the car will be shortened.

Moreover, the neutral coasting car is easy to stall, resulting in the failure of the brake booster drum and the decline of braking performance.

2. Hanging neutral gear is not fuel-efficient, and sometimes it is even more fuel-efficient, which is related to the working mode of the EFI engine.

EFI engines can be used to determine the amount of fuel injected according to the computer program. In the case of gearing, if the owner releases the throttle, the computer will let the car enter coasting mode, and for a long time, the engine is not injected; If you coast in neutral, the computer will put the car into idle mode and the engine will still be injected. That's why coasting in a time is more fuel-intensive.

For the above two reasons, the automatic transmission cannot be put in neutral gear while driving.

The damage is relatively large.

There is a fundamental difference between the emptiness of automatic transmissions and manual transmissions: the manual clutch separates the engine from the transmission body without touching each other, while the automatic keeps the running-in state all the time, even the N gear is always in a state of wear between the gears, that is, even if it is empty, the transmission is always working.

As mentioned upstairs, rolling will cause insufficient oil pressure, reduce lubrication effect, and cause greater damage to the gearbox.

Coasting in neutral (N) mode can cause insufficient oil pressure in the hydraulic lines in the automatic transmission, reducing the lubrication effect and damaging the automatic transmission.

1. Long-term neutral stop of automatic transmission cars will damage the service life of the gearbox.

2. If you stop in neutral, the steel claw and gear in the gearbox will be competitive, and the gearbox that should have rested has been holding back, in this case, as long as the car hits, the gearbox will be more vigorous, making a huge buzzing sound, and the car will tremble. When pulling from N gear to other gears, it will be very difficult, and it will cause a huge impact on the gears when it is disengaged, so it is recommended to stop in P gear.

3. In addition, if you are used to parking in N gear, there is a certain risk, such as a slippery slope.

4. The correct sequence: stop and step on the brake - gear into N gear - release the foot brake - pull the handbrake - enter P gear - turn off. (If you are on a slope, the third step is to pull the handbrake first, then release the foot brake, then turn off the engine, and enter the P gear) In short, no matter what the terrain is, you must first let the car level by itself, or first use the handbrake to firmly stabilize the body, and then enter the P gear to turn off.

The automatic transmission car is in neutral gear (N) when driving, so that the engine speed and the number of revolutions of the driving wheel are high, and suddenly the neutral gear is hung, which will cause a great impact on the automatic transmission; When you need to accelerate again, and then N hook into D, so that the number of drive wheel revolutions is higher, and the engine speed only stays at the number of revolutions at idle speed (generally about 750 rpm), so that the impact on the gearbox is greater, and when the neutral gear slides, because the automatic transmission does not rotate, the lubrication system can not work normally, which is also an important reason for the accelerated aging of the automatic transmission! Remember, don't put an automatic car in neutral! It should also be noted that when you are about to make a U-turn, the car has to move back and forth, and when you are moving forward, the car has not stopped, do not hook from D to R and then to R, or when you are reversing, the car has not stopped, never from R to N and then to D.

That is, don't change gears if the car doesn't stop, and you must wait for the car to stop before changing!

Coasting in Nth gear doesn't save much fuel, or it's almost the same as coasting in D. The manual gear is different, and coasting in neutral saves a bit of fuel and does little damage to the gearbox! When it is said that sliding in neutral is allowed under absolutely safe conditions, please don't neutralize the mountain road, life is more important than oil!!

The automatic transmission car can not be hung in neutral gear while driving, the reasons are: 1. The automatic transmission car is in neutral gear during driving, the engine and the driving wheel lose contact, and the car relies on its own inertia to move forward, and the braking force will decline, which is easy to cause rear-end accidents; 2. Hanging neutral gear is not fuel-efficient, sometimes even more fuel-efficient, related to the working mode of the EFI engine, the car neutral coasting computer will let the car enter idle mode, and the engine is still injected; 3. It is easy to damage the automatic transmission, and the driving speed of the car is different from the engine speed after hanging neutral gear, resulting in insufficient oil pressure in the hydraulic pipeline in the automatic transmission, and the transmission cannot be lubricated normally, which will not only increase the friction force and reduce the lubrication effect, but also damage the friction plate inside the automatic transmission.

Can an automatic transmission car be in neutral while driving? The precautions for automatic transmission car driving are: 1. The automatic transmission car has protection and interlock function for dangerous actions, and the D gear can be switched arbitrarily between the D gear and the N gear, and the D gear will be switched to the R gear or the P gear will be switched wrongly; 2. When the vehicle is parked on a steep slope and its gravity is greater than the power at idling, the vehicle will slip and should start with the handbrake; 3. Coasting in neutral gear for a long time will lead to insufficient oil pressure in the hydraulic pipeline in the automatic transmission, increase the friction force, reduce the lubrication effect, and damage the friction plate inside the automatic transmission; 4. When the automatic transmission car is parked or idle for a long time, first step on the brake and hang into N gear, pull on the handbrake and release the brake pedal, and hang into P gear after the vehicle stops.
