Why does a car s gearbox frustrate?

Under normal circumstances, when the driver slowly refuels, the original logic of the computer only needs to upshift to complete the acceleration, but due to excessive strength, the clutch finds that it needs to downshift to complete the intention of the rapid acceleration on the way upshift, and immediately downshifts at this time, so that the power can not be transmitted smoothly in the time of the trip. This makes it easy to get frustrated.

Most of the reasons are because the gearbox is not fast enough, and the upshift speed can't keep up with the speed at which you step on the accelerator, so the moment the gearbox shifts, the frustration comes. Most of them are because of the intervention of the energy system, once the driver releases the accelerator pedal or presses the brake pedal, the generator will immediately start working, and it will catch the engine, causing some burden to the engine, affecting the speed of the engine, so that the engine speed is not synchronized with the speed of the clutch plate, so that there will be a feeling of frustration.

Many car owners have this situation, due to the frequent switching between the gears and the second gear when driving at low speed, the clutch is constantly separated and combined, and the power transmission can not be completed smoothly in a short time, which causes the common low-speed frustration, and there will be a sense of frustration when starting and low speed, which is normal when the turbocharging intervenes at low speed, which affects the engine speed.

Abnormal reasons, gearbox gear program setting problems; Dirt and impurities inside the gearbox, internal dirt or impurities lead to the inability to effectively adjust the oil pressure of the gearbox, resulting in frustration; Transmission heat dissipation problems, poor transmission heat dissipation, will lead to abnormal high temperature of the gearbox, which will affect the performance of the transmission oil, if the temperature exceeds 120, the rubber sealing material of the gearbox will become hard, resulting in transmission leakage, thereby affecting the oil pressure, resulting in frustration.

SolutionCheck whether the temperature of the gearbox is normal, if not, check the gearbox cooling system, there is no problem with heat dissipation, continue to look at the following; Reprogram the gearbox computer system; Change the transmission oil, it takes 2 years or 40,000 kilometers to change the transmission oil; Inspect the internal valve body of the gearbox for damage.

In general, transmission stallions can be attributed to poor shift quality and malfunctions. In some cases, poor shift quality is inevitable due to objective reasons, so it is normal for the gearbox to stall at this time. And the frustration in the event of a failure is what you really need to pay attention to.

Therefore, it is normal for the gearbox to have occasional setbacks, as long as it is not a problem with the gearbox, the occasional setbacks are not a big deal, and there is no need to worry too much, after all, it is not an electric car. If you want to avoid setbacks, the easiest way is to drive without "meat", don't rub, go when you should go, don't hesitate, as long as the road conditions are suitable, step on the throttle a little more, so that the engine and gearbox like it.

When the gearbox is driving, there is a sense of frustration, then one of the reasons we have to consider is that there are some impurities or dirt inside the machine, which is likely to cause a great change in the oil pressure of your car gearbox, which will cause the frustration of the car gearbox!

The clutch found that it needed to downshift to complete the intention of the rapid acceleration on the way upshift, and immediately downshifted at this time, so that the power could not be transmitted smoothly in the time of the trip, so that it was easy to produce a setback.

Because of the adjustment of the speed switch and a certain amount of wear.

If your gearbox is experiencing frequent stuttering, it is likely that there is a problem with the programming of your car's gearbox.

Because the speed of the car changes all the time, the sonic box also changes according to certain factors.

I've never liked the GL6's gearbox, and I feel like the timing of the upshift is wrong. The speed above 45 is only in 4th gear, and above 65 is only in 5th gear, and if you want to go to 6th gear, you have to exceed 85 per hour. According to this logic, it is usually basically switched between 3-4 gears in the city, and it is not easy to think of 5 gears, and it is almost impossible to go to 6 gears.

The speed of 5th gear is lower than 62 left.

Because the car has been used for a long time, there will be some dirt in it.

It took a long time and friction arose.

Sudden acceleration or braking followed by acceleration are the two situations that are most likely to cause frustration.

There is a process for switching, and if it is serious, it means that there is a problem.

If this kind of problem occurs frequently, you need to go to the repair shop to take a look.

If it's an engine failure, it's actually pretty good for us to judge. We can judge that it is a ** fault before we start. See if the idle speed is unstable, and whether the engine stagnates in slow acceleration and sharp acceleration has any stuttering.

If there is a lack of acceleration, it should be an engine failure. If everything is fine with the engine, it may be a transmission failure. Secondly, the frustration generated during the gearbox shift process during the acceleration process is the most common in AT or dual-clutch models, and the slight setback in the gear shift process cannot be avoided.

Why emphasize two kinds of frustration at the beginning, these two kinds of frustration, are different nature, if it is a fixed period of frustration, this situation can basically be determined to be a gearbox, this is usually better to judge, in the process of a vehicle upshift, such as 2 liters 3 gears, 3 liters 4, etc., or 4 downing 2 gears when the pause, the most important one, is these abnormal phenomena, is there repetitiveness? If you can find a repeatable pattern, it's easy to solve problems like going to a quick repair shop.

If your car is an automatic transmission, there was no setback before, and there has been a setback recently, that is, there is a problem with the gearbox, first see if you need to change the gearbox oil, if you have not solved the problem with the oil change, the American and German systems are the internal friction plates of the gearbox are broken. The Japanese system is that the valve body is broken. The gearbox is a transmission component, and the gears in it have different transmission ratios, and at the same engine speed, its different gears correspond to different speeds, that is, at different wheel speeds.

That is to say, at the same speed, using different gears, the engine will also operate at different speeds.

If there is a sense of frustration in the process of driving, there are many possible reasons, the more common is the ignition system failure, most of the vehicle frustration is caused by the ignition system problems, such as spark plug electrode ablation is serious, cylinder line leakage, ignition coil failure are more common reasons.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

If this phenomenon is said to be this automatic transmission or dual-clutch gearbox, this is mainly when the gearbox is shifted, the solenoid valve is not working smoothly or the gap is relatively large when the clutch is combined, this phenomenon will occur, if it is an AT gearbox. The transmission oil needs to be replaced, and if it still doesn't work, then the solenoid valve inside the gearbox needs to be cleaned. If this phenomenon occurs in the dual-clutch gearbox, this is mainly due to the large wear gap of the clutch system, and this phenomenon occurs, and this needs to be dealt with, then the clutch needs to be replaced.

Questions. The 17 A4L, the clutch that had just been replaced, and the transmission oil, after driving more than 2,000 kilometers, had a setback.

This is still a dual-clutch gearbox, this is a common problem of dual-clutch gearbox, and there is no way to change a design flaw. It's just that after running more than 2,000 kilometers now, this phenomenon occurs, and then you go to replace it, and there may be no way to change it after the replacement. It is a common problem with dual-clutch transmissions.

Questions. It's not a pause when changing gears, but an occasional time in normal driving.

That's what he is. This dual-clutch gearbox has this phenomenon, which is also a common problem of this Audi including Volkswagen's dual-clutch gearbox.

Questions. That kind of thing means that it can't be repaired, isn't it too dangerous to run at high speed like this?

Yes, there is no way to do this dual-clutch gearbox, which means that this phenomenon may still occur after you replace it.

Questions. Can this kind of fault be opened?

If this phenomenon is not turned on, it will be said that this phenomenon may occur, and it is possible to run at high speeds, and it is very dangerous to suddenly interrupt this power.

Questions. So is this car scrapped?

This one you can scrap in advance. It's just that there aren't many subsidies for you.

It is very likely that there is a problem with our engine, and secondly, it is also caused by insufficient oil supply, which is also related to the gearbox, so we must pay attention to maintenance at this time.

It is very likely that there is serious dirt inside the machine, which greatly affects the feeling of driving, it should not be that there is a problem with the gearbox, but that the carbon inside is too serious.

It may be because your engine is not maintained, and the carbon deposits are particularly severe, so this will happen. There are also certain problems with the gearbox.

It is estimated that there is a problem with the gearbox, or it is possible that the driver's skills are not good. It is true that there is a problem with the gearbox.

The reason for the serious collapse of the car gearbox is to shout Liang Shen:

1. There are stubborn dirt and impurities inside, especially in the valve body, the dirt and impurities accumulate to form a blockage slag sale, which leads to the inability to effectively adjust the oil pressure, resulting in the occurrence of frustration impact slippage. At the same time, the problem of high temperature of the gearbox cannot be ignored. According to the Automatic Transmission Repair Association, it is called

More than 90% of all faulty automatic transmissions are caused by overheating;

2. High temperature will destroy the quality and friction characteristics of automatic transmission oil, increase friction and wear, and transmission noise will follow, and at the same time, sludge (impurities or dirt) will also be generated inside the transmission (such as the valve body), resulting in frustration and impact of the gearbox. If the temperature exceeds 120 °C, the rubber sealing material will begin to harden, eventually leading to leakage and reduced hydraulics. If the temperature is higher, the gearbox starts to slip, which in turn causes the temperature to rise even higher.

Audi and other high-end models will alarm and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped;

3. Only by removing the stubborn dirt and impurities in the gearbox and effectively controlling the working temperature of the gearbox can the gearbox problem be completely solved and its recurrence can be prevented. This is also the key to achieving "no dismantling and repairing to solve transmission failures", and the specific content can be detailed in the search engine.

Millions of car purchase subsidies.

The reason for the frustration of the gearbox is: the oil temperature of the gearbox is too high, and the stubborn dirt and impurities in the gearbox appear, which form a blockage in the valve body, resulting in the poor movement of the solenoid valve, and the inability to adjust the oil pressure in sequence, resulting in frustration, impact and slippage failure. Transmission frustration is a shock sensation caused by the inertia of the moving parts inside the engine, and transmission frustration can be attributed to poor shift quality and failure.

The functions of the gearbox are: 1. Change the transmission ratio, the need for traction under different driving conditions, so that the engine can work under favorable conditions; 2. Realize the backward driving of the car; 3. Interrupt the power transmission, the engine starts to idle and runs, the car shifts gears or stops, and the power transmission to the driving wheel is interrupted; 4. To achieve neutral gear, when the clutch is engaged, the transmission stops outputting power.

Because automatic transmission oil is not the same as manual transmission oil, automatic transmission oil plays a lubricating role and does not answer. It also plays the role of mode key shifting, so if it is not replaced for a long time, it will lead to poor lubrication of the gearbox, serious wear of components, shorten the service life of the gearbox, and also lead to a strong frustration of the gearbox shift.

Nowadays, the automatic transmission technology is becoming more and more advanced, the control mechanism is becoming more and more sophisticated, and the corresponding requirements for transmission oil are also higher and more sophisticated, and some non-original oil may cause some problems. And these differences are perhaps best known only to engineers. After ruling out other causes, there are also reasons to suspect that the problem is caused by the unsuitable transmission oil itself.

Main advantages: The transmission oil is added to the gear, and the foam is stirred, which causes the oil pump to suck the foam and the oil pressure drops, which will cause the clutch plate to release the pressure and cause slippage and frustration. The transmission oil is missing, starting the transmission oil pump to circulate a part of the remaining oil is insufficient, which may also lead to a drop in oil pressure and a setback.

Many car owners will always have a sense of frustration when changing gears in daily driving, especially after braking, acceleration or sudden acceleration is more obvious, so what is the reason for the gearbox frustration?

The first reason: there is a problem with the driving habits of the car owner. When driving the vehicle, because the technology is not very skilled, when driving, the gear and the speed of the vehicle are seriously mismatched, and there will be a situation where the gearbox is rough and eats a meal.

For such a situation, car owners and friends should practice more on their own and have a good relationship with their own cars. Once you get acquainted with them, the frustration decreases.

The second reason: problems with the transmission of the car itself. If your car gearbox does not dissipate heat in time, the temperature of the gearbox will be too high, and it is easy to leak oil, resulting in a decrease in oil pressure.

The owner may not know that this gearbox return to the bench judgment is completely driven by oil pressure to drive the clutch to run. The hydraulic oil pressure is affected and there is a time difference, which is one of the main reasons for transmission stuttering.

The third reason: it is because there are too many impurities in the car gearbox, and the dirt affects the normal operation of the gearbox, resulting in the frustration of the car.

Therefore, car owners, when the car has obvious gearbox setbacks, first consider whether there is a problem with the driving leakage operation of the car. If there is no problem, it is necessary to check whether the operating temperature of the transmission is within the normal range. If there is no problem in either case, then it is advisable to go to a repair shop for an inspection to avoid unnecessary losses.
