Why is there more frustration after replacing the transmission module?

In many cases, the automatic transmission is not damaged by the internal valve body, but by stubborn dirt and impurities inside, especially in the internal valve body, the dirty impurities accumulate to form a blockage, resulting in the inability to effectively adjust the oil pressure, resulting in the occurrence of the problem of stagnation, impact and 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. ”

High temperatures can damage the quality and friction characteristics of automatic transmission fluids, increase friction and wear, and transmission noise will follow, as well as sludge (impurities or dirt) will also be generated inside the transmission (e.g. valve body), resulting in transmission setbacks and shocks. If the temperature exceeds 120 °C, the rubber sealing material will begin to harden, eventually leading to leakage and reduced hydraulic pressure. 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 call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped.

Therefore, 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 prevent its recurrence. This is also the key to achieving "no dismantling and repairing to solve transmission failures", which can be described in detail.

Dual-clutch? There are all setbacks in the low gears.

Generally, there are about 10 days after replacement, and the run-in will slowly get better. You can ask if the 4S is caused by the fact that the gearbox computer has not been completely brushed.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The gearbox is a very important part of the car, the quality of the gearbox affects the performance of the car, and the transmission oil that affects the gearbox is the gearbox oil, the gearbox oil can play a role in lubricating and cleaning the gearbox, can ensure the normal operation of the gearbox, there are many car owners have ignored the replacement of the gearbox, what is the impact of the gearbox oil is not changed? Headlines Lai Yan.

The transmission oil does not change will affect the performance of the car, in the process of transmission use, the friction between the metal parts will produce debris impurities, and the transmission oil will become dirty after a long time, which will affect the shifting, the oil passage will be blocked, resulting in unsmooth shifting, poor transmission effect, weak acceleration, and will also increase fuel consumption to a certain extent. The reduced efficiency of the transmission oil can easily lead to poor lubrication, accelerated wear of components, and corrosion of parts, thereby shortening the service life of the transmission. Strip Lai Piercing Head.

Why did he feel more frustration after changing the gearbox, this should probably be because of this change, so he may not be very tired, so it should be this kind of frustration.

Gearbox stuttering is something that needs to be fixed. Transmission frustration is the sensation of shock caused by the inertia of the moving parts inside the engine, and transmission frustration can be attributed to poor shift quality and failure.

Maintenance method of the gearbox.

1. Check the oil level frequently; 2. Do not skip the upgrade gear; 3. Do not forcibly pick up the neutral gear; 4. Do not shorten the time of idling and hot up; 5. Avoid hitting teeth when hanging gear.

Problems with a lack of oil in the gearbox.

1. There is a sense of frustration and uneven gear shifting; 2. When stepping on the accelerator, the increase of the speed is not proportional to the increase of the speed, the speed increases normally, but the speed cannot be raised; 3. Serious damage will cause the gearbox to heat up and burn out the gearbox, because the bearing lacks lubrication, the friction factor increases, and it is easy to be damaged; 4. The noise is obvious, especially when driving at high speed.

Check if you don't have enough oil or if you have overfilled. After replacing the engine, the gearbox is frustrated because of insufficient oil or filling is accompanied by excessive guide letter Qing family, you can go to the transmission maintenance manufacturer for maintenance, the main symptoms of the gearbox slip and frustration are in the process of starting or driving, the shock, vibration, and frustration generated by the gearbox when upshifting are all relatively strong, or there is a feeling of jamming and shrugging when accelerating sharply.

The gearbox is crumbling? Causes of gearbox failure: 1. Upshift setback, most of the reason is because the speed corresponding to the gearbox is not fast enough, and the upshift speed cannot keep up with the speed of stepping on the accelerator, so at the moment when the gearbox shifts, the setback will come; 2.

Most downshift setbacks are due to the intervention of the energy** system. As soon as the driver releases the accelerator pedal or presses the brake pedal, the generator will immediately start working, which will put a load on the engine cong motor, which will affect the engine speed, so that the engine speed is not synchronized with the clutch plate speed, resulting in frustration. 3.

Backwards at low speeds. This is the case for many car owners. Due to the low speed when driving the gears on.

Frequent switching between the first and second gears, the clutch is constantly disengaged and combined, and the power transmission cannot be successfully completed in a short period of time, resulting in the common low-speed retreat. There is a sense of frustration when starting low and running at low speeds. Normally, turbochargers run at low speeds, which affects engine speed.

In fact, the automatic transmission type of cars on the market has been greatly improved compared with the previous in terms of the smooth gearbox, but some cars still have a sense of frustration after using it for a period of time, so what is the problem of the strong frustration of the gearbox shift?

1. If the owner's vehicle gearbox is AT, then in this case, it is normal to have a slight frustration, because this gearbox is composed of gear gears, and there will be a slight frustration when switching gear gears.

2. It is also possible that the oil inside the gearbox has deteriorated, or the gearbox oil has expired, but the owner has not replaced it in time, and the gearbox oil will not play the role of lubrication, which eventually leads to dry grinding of the gears inside the gearbox and frustration.

3. When the solenoid valve fails, the vehicle will also feel frustrated when changing gears, so it is necessary to check or replace the solenoid valve in time.

In the middle of the forum, there is a circle of friends in the post list, you can go to find your organization, and you can ask in the circle.

Hello, happy to answer your <>

Reasons for downshift frustration after replacing the transmission assembly: 1The transmission assembly is improperly installed, resulting in incorrect gear clearance and screw preload.

2.Transmission fluid is not replaced in a timely manner, resulting in poor lubrication of the transmission system, reduced acceleration, and frustration. 3.

The parameter mismatch between the old and new transmission assemblies causes the transmission efficiency to decrease. The above are the reasons for the downshift frustration after replacing the transmission assembly.

Downshifting is frustrated after changing the transmission assembly.

Expansion: The gearbox of the car can be divided into two types: manual and automatic, and the manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations. The automatic transmission AT is composed of a hydraulic torque converter, a planetary gear, a hydraulic transmission system and a hydraulic control system, which achieves variable speed and torque through hydraulic transmission and gear combination.

then play macro.

Summary. Hello, this situation illustrates. Vehicle transmission failure, the relevant reasons and treatment methods are as follows First, the vehicle transmission oil is too dirty or the transmission oil loss is caused by this phenomenon, it is recommended to check the transmission oil first, if there is a problem, you need to replace the new transmission oil.

This phenomenon caused by the failure of the valve body inside the second gearbox, this is the need to use a computer to read the fault of the gearbox system, according to the fault ** further diagnosis and analysis, the valve body failure, if there is a problem, need to replace the new valve body. Third, the problem of gearbox shift logic caused by this phenomenon belongs to the gearbox program garbled, in this case, it is necessary to use a special computer to redo the gearbox program upgrade, or match the reset! Hope mine can help you!

This phenomenon caused by the failure of the valve body inside the second gearbox, this is the need to use the computer to read the fault of the gearbox system, according to the fault ** further diagnosis chain and analysis, the valve body failure, if there is a problem, need to replace the new valve body.

Third, the problem of gearbox shift logic causes this phenomenon to belong to the gearbox program garbled, this situation is that you need to use a special computer to redo the upgrade of the gearbox program, or match the reset! Hope mine can help you!

Make a software match. Upgrade processing, is to upgrade the gearbox computer, wear and tear is inevitable You only need to change the gearbox oil normally according to the number of kilometers.

After studying once, you can get back to normal.

In this case, you must learn, but you are not sure how long it will last, and there is wear and tear on the inside, so you can only continue to learn to use it.

Under normal circumstances, the gearbox will not have frustration, but if there is frustration, it should be dealt with in time according to the reason, let's understand what is going on with the frustration of the gearbox?

1. If there is a problem with the quality of the gearbox, it will also make the gearbox frustrated when using a problem, and it must be replaced in time, and it is necessary to choose the best gearbox in a regular organization.

2. The amount of transmission oil filling is not appropriate. The gearbox of the car needs to be injected with transmission oil in time during the use process, but if the amount of injection is not appropriate, it will also cause frustration in the gearbox.

3. The gearbox is selected by the incorrect specifications. When choosing transmission oil, you can not add different models, it is best to add the same one, and pay more attention to the production date of transmission oil, do not exceed the specified use time.

4. There are impurities or dirt inside the gearbox. When the gearbox has this kind of problem, the oil pressure of the gearbox can not be effectively adjusted, so that the gearbox has a frustration, and it needs to be cleaned up in time.

It is recommended that you go to the service station to check it out! If you have any problems with the car, you can go directly to the service station! Ask them to check it out for you and see what the problem is! How to deal with it!
