What do you know about the 4 prohibitions of automatic transmission models?

1.N gear gliding is not allowed.

2.It is not allowed to directly hang the P file.

3.It is not allowed to be ded to the end.

4.Do not park the car to hang R gear in front.

In fact, there are many inaccuracies, whether it is automatic or manual, not shifting for a long time, stepping on the accelerator all the time, waiting for the red light not to hang N gear, etc.

There are many things to pay attention to in automatic transmission models, among which there are the following four inadequacies. 1.No neutral glide 2

It is not allowed to stop and immediately call the P gear, and you need to turn off the handbrake and then enter the P gear 3The car is not parked and is not allowed to hang R gear 4Trailers are not allowed in neutral gear, and the trailer needs to lift the front of the vehicle, or be towed to the trailer and taken away.

The driving requirements of automatic transmission are higher than those of manual transmission, because its configuration and machinery and equipment requirements are more precise, so we must pay attention when driving, first, automatic transmission models do not frequently change gears, second, do not hang neutral gear with inertia coasting in order to save fuel, third, the vehicle is not stable, do not pull the handbrake, fourth, do not ignore the maintenance of the gearbox

1. N gear coasting is not possible during automatic transmission.

Not to mention that coasting in N gear does not meet the safe driving norms, and it is not more fuel-efficient than coasting with gears, and more importantly, it is actually very harmful to the car. The automatic transmission also needs gear oil to lubricate, when the gear is placed on the neutral gear during driving, the transmission oil pump can not supply oil normally for lubrication, which will increase the temperature of the relevant parts in the gearbox, increase the gear wear, and easily damage the gearbox. In fact, today's EFI cars are no better than the old carburetor cars, and coasting in neutral gear is not only dangerous, but also does not serve the purpose of fuel saving.

In fact, at the beginning of the design of the car, the N-gear was designed for short-term use.

2. When the car stops, do not push into the P gear first.

When the car stops, step on the brake is the first to push into the P gear or pull the handbrake first, pull the handbrake first, so that the car can bear the burden of external force by the handbrake system, and the first to hang the P gear will cause the external force to be borne by the gearbox when parking, once subjected to violent external force (such as collision), it may cause damage to the inside of the gearbox or the gear can not be hooked up, etc., the gearbox will definitely be greatly damaged. Even if you don't consider the external collision, if you stop on a ramp and push directly into the P gear to stop, you should also consider whether the P gear will be damaged.

3. Don't tow the car when it breaks down.

When the car breaks down and needs to be towed, the automatic transmission is not like the manual transmission, which can be towed at will when hung in neutral gear, and the transmission may be damaged if the automatic transmission is towed arbitrarily. After the car fails, the automatic transmission oil pump can not operate, the parts lack lubrication and cooling, when the driving wheel hits the ground and drags the gearbox will also drag the gearbox to run together, damage the gearbox, when towing, you should first determine whether the automatic transmission car is front-wheel-drive, rear-wheel drive or four-wheel drive, and the driving wheel can not be dragged.

Fourth, the car is not parked and do not hang R gear.

Automatic transmissions are more delicate than manual transmissions, and when the car is not completely stopped, it will directly engage from D gear to R gear, which will have an impact on the transmission, and often this operation will cause the transmission to fail prematurely.

It is not allowed to step on the clutch, it is not allowed to step on the clutch, it is not allowed to step on the clutch, it is not allowed to step on the clutch.

For some novice drivers, if they want to buy a car, they will first choose the automatic transmission model. Because the automatic transmission model is easier to drive than the manual transmission, you don't always have to go back and forth. But there are many things that cannot be done in automatic transmission models.

For example, while driving, you can't put neutral gear, and you can't keep the car in D gear all the time. You can't stop the car and hang the P gear immediately. These are all inappropriate behaviors that drivers need to be aware of.

Many drivers who drive automatic transmission models always can't help but put their cars in neutral gear when driving their cars. I would think that this would be more fuel-efficient. In fact, this is a wrong perception, which is likely to bring more serious harm, because after hanging neutral, it is easy to cause the gearbox to wear and tear.

If you put the car in neutral gear when going downhill, it is likely to increase the braking distance a lot. In this way, it will bring a lot of trouble to the later driving. <>

While driving, you can't keep in D gear. Many veteran drivers, whether driving uphill or downhill, like to put the gear in D gear. In fact, such a practice is likely to aggravate the load on the car and drag the gear.

So when going uphill, you should hang the gear to the L position, instead of using the D gear all the time. When the driver stops, he has been accustomed to hanging the gear directly to the P gear, but this habit is very incorrect. <>

Because after parking, immediately put the car in P gear, it will increase the external force, and for a long time, the service life of the gearbox will be greatly reduced, and it is also one of the behaviors that hurt the car. The correct way to do this is to park the car, and after a few minutes, hang the P gear, which can give the car a buffer time. It can also effectively extend the service life of the car.

Although every family can afford to buy a car now, it also needs to be cared for.

When driving an automatic transmission car, it is not allowed to drive with both feet, no, one foot on the brake, one foot on the accelerator is that in the event of an emergency, it is very likely to step on the wrong step, can not slide in neutral gear, the reason is that neutral coasting will not save fuel, but also cause damage to the car, can not use D gear for a long time, the reason is that the use of D gear for a long time can not only increase carbon deposits, but also increase fuel consumption.

It is not allowed to put into reverse gear or P gear when the vehicle is not stationary, it is not allowed to hang into D gear or P gear when waiting for a red light, and it is not allowed to slide in neutral gear; These behaviors may bring hidden dangers to driving safety, so you must pay attention to follow the rules when driving to ensure safety.

When the car is not stopped, it cannot be pushed to the P gear, when the car fails, it cannot be towed, when the car is not stopped, it cannot be hung in R gear, and the car cannot be coasted in N gear when driving. The act of hanging the P file directly after the ignition is turned off. The reason is that such behavior will cause more serious damage to the car and will also lead to a reduction in the life of the car.

You can't use N gear to slide, when the car stops, you can't push the P gear first, you must warm up the car in advance when driving an automatic transmission model, pay attention to the rotation of the gears, and obey the rules of driving the car. This avoids damage to the gearbox and helps to ensure the operation of the gearbox.

<> "The first one is that you are not allowed to slide in neutral; The automatic transmission is different from the manual transmission model, the automatic transmission is powered by multiple clutch friction plates, if in neutral mode, these friction plates will rub on their own, the loss is very large, and it is even possible to enter the overhaul period in advance.

The second is that it is not allowed to hang the P gear before the car is parked; We all know that the P gear is used for parking, if the vehicle has not completely stopped the stupidity, and hurriedly hang up the P gear position, which may seriously damage the teeth inside the transmission and bury the accompanying wheel, and there will be abnormal noise or tooth snorting in the future.

It is worth noting that the damage caused by this misoperation to the transmission is permanent and irreversible, so these regulations must be complied with in the operation method.

The third is that the vehicle is not allowed to hang the R gear before it is parked; The R gear is the reverse gear, which is the opposite aspect of the forward gear. Therefore, it must be equal to the complete stop of the vehicle before the R gear can be engaged, otherwise the result will be the same as the second one.

the fourth is not allowed to go to the world in D gear; In other words, it is not allowed to hang a D gear as all forward gears. D gear is the general term of all forward gears, but in addition to this gear, there are also L gear and S gear, etc., the role of L gear is to use when the uphill can go downhill, especially when the slope is large, which is very beneficial to prolong the service life of the transmission and improve the driving efficiency of liquid cracking. There is also S gear, which is also a sports gear, which is generally used when overtaking, which can increase the output power of the engine to facilitate overtaking.

<> "When waiting for a red light, it is forbidden to hang the P gear.

When many people are waiting for a red light, they often send Chana to use the way of putting the P gear to stop the car, which is wrong. When you put on the P gear, the pressure of parking all falls on the locking device of the gearbox, which will cause some damage to the gearbox, and if the vehicle is hit at this time, it will directly lead to the damage of the gearbox. Therefore, the best way is to step on the brakes in D gear, and the safer way is to pull the handbrake in N gear.

The car did not stop and could not be put in reverse gear.

This is a mistake that many novice drivers and female drivers often make, the car has not stopped and hung the reverse gear, it is time to switch from D gear to R gear, and the reverse rotation pressure of the moment will be pushed to the reverse clutch, and in the long run, it will cause damage to the clutch plates, and even the gearbox will be damaged. Therefore, it is necessary to park the car steadily, and then go to the reverse gear, which is the most correct parking operation.

Coasting in neutral is prohibited.

Many old drivers are accustomed to manual transmission, often through the neutral coasting operation to achieve the effect of fuel saving, manual transmission does have an effect, but automatic transmission is not suitable. The automatic transmission does not coast in neutral gear, which does not play a role in fuel economy, but will damage the transmission. Because when the vehicle hangs N gear, the transmission oil is only by the idle oil pump**, which can only achieve local lubrication, and the gears and multi-plate clutches of other transmissions cannot be lubricated, which will damage the gearbox due to insufficient lubrication and dust for a long time.

Don't keep in D gear when going uphill and downhill.

When going up the slopes, you can switch to a low gear in manual mode to maintain enough power. When going down the slope, you should also change to the low gear of manual mode to avoid the brake pad temperature being too high and causing it to fail due to the prolonged application of the brakes, which will have serious consequences.

Conclusion: Although the automatic transmission is very simple, if it is damaged, the cost of later maintenance is much more expensive than the manual transmission, so don't do these driving operations that destroy the car.

<> "After years of development in the domestic automobile market, automobile consumption has become very mature, from the previous in most of the manual transmission models, to the development of automatic transmission models have also been basically popularized. According to relevant data, the proportion of automatic transmission models in the car has been as high as 70-80%, and the convenience of automatic transmission model operation has been loved by many consumers.

Although the automatic transmission model is easy to operate, it is about 10,000 yuan more expensive than the manual transmission, which means that the automatic transmission model is higher. The automatic transmission is high, and it can also explain the maintenance requirements of the automatic transmission, which is higher than that of the manual transmission, especially in terms of operation specifications, if you do not pay attention to it, the maintenance cost of more than 10,000 yuan is not affordable for every consumer. Therefore, here is a summary of the "4 prohibitions" principle for the operation of automatic transmission models, one hurts the car more than the other, don't be stupid and don't know, look around.

The first is that it is not allowed to glide in neutral gear; The automatic transmission relies on multi-piece friction plates to transmit power under the action of the hydraulic balance, if the gear is neutral, these friction plates will become very loose, and there will be free movement between each other, resulting in very large wear. Long-term use will lead to weak refueling, which may be caused by severe wear of the friction plates, or impurities after friction blocking the oil circuit. Therefore, during driving, it is not possible to coast in neutral gear, otherwise the automatic transmission may enter the overhaul period in advance.

The second is that the vehicle is not allowed to hang the P gear before it is stopped; We know that the P gear is the parking gear, that is, the stop gear, which locks the inside of the transmission. If the vehicle is not parked, it is hurriedly hung up in the P gear, and the consequence is that there may be teeth inside the transmission, resulting in gear damage, or even scrapping directly.

The third vehicle is not allowed to hang R gear before it is unstable; The reason is the same as the second, except that the R gear is a reverse gear. In the process of driving, be sure to stop the vehicle and then hang the R gear, one forward and one backward, if not completely stop in a hurry to hang the R gear, the consequence is also to cause damage to the gear.

The fourth is that it is not allowed to use the D gear for a long time; Although D gear is suitable for most road conditions, for some rough road sections, or when going up and down hills, L gear should be used reasonably. Not only can you get the best performance out of your transmission, but it also saves fuel and extends the life of your transmission.

Nowadays, more and more people are buying cars, and for everyone, cars seem to have become a very important means of transportation, especially many automatic transmission models have won everyone's love. For automatic transmission models, there are some things that are not allowed to be done that need to be kept in mind by car owners, and the following is to introduce some of these things that are not allowed to be done by automatic transmission models, interested friends can come to learn about it. <>

It is not possible to engage reverse gear directly until the vehicle has come to a standstill

There are many drivers who are accustomed to manual transmission models and still can't change their previous driving habits after driving an automatic transmission model. They will even put the car in reverse gear when it is not completely stationary, which is not right, if the driver always puts the reverse gear in the car when the car is not completely stationary, the car's gearbox may be damaged over time. I believe everyone knows that the gearbox is a very important configuration of the car, so it should be taken care of.

It is not allowed to frequently engage reverse gear before the car is stationary. <>

When waiting for a red light, do not apply the brakes frequently

When the driver is driving an automatic transmission model, can not wait for the traffic light to frequently step on the brakes, the correct steps to stop are as follows: first lightly step on the brakes, then hang down N gear, and then gently pull the handbrake, wait for the car to slowly stop and then release the foot brake, then you can push the gear to P gear. I would also like to remind everyone that you should not use your left foot to apply the brakes of automatic transmission models.

Automatic transmission models are not allowed to coast in N gear at will

Some friends who drive automatic transmission models often fall into such a misunderstanding, that is, they mistakenly think that neutral coasting can save the car's fuel consumption, in fact, this approach is wrong, neutral coasting not only will not help the car save fuel consumption, but also may bring harm to the engine. Coasting in neutral is equivalent to turning the car into a kite with a broken string, which can be very dangerous, just like falling into a state of dissociation. For their own safety, drivers should still avoid this wrong way of operating.

Instead, it is better to coast in D gear, which can save fuel and improve driving safety.
