It is necessary to inspect and maintain the automobile transmission, what are the reasons?

I often hear similar questions from car owners: "Why do you need to repair an automatic transmission, doesn't the repair manual say that you don't need to repair it?" In response to these problems, I would like to share with you the principles of automatic transmission maintenance.

The gearbox is a very complex system. If maintenance is lacking, problems such as untimely gear changes, reduced sensitivity, and squeaks or noises can occur.

Long-term use, transmission oil accumulation is too much, and regular maintenance is required; While the transmission oil that is routinely replaced cannot be completely replaced, by using professional products and equipment for regular maintenance, it can effectively prevent transmission problems.

Transmission maintenance refers to the need to clean the inside of the transmission after the car has traveled a certain distance, because the inside of the automatic transmission is basically a channel full of fuel. If the oil circuit is blocked, it will affect the normal use and damage the gearbox, and the next step is to replenish the gearbox oil in time.

<> maintenance of an automatic transmission is mainly to clean the inside of the transmission, because the inside of the automatic transmission is basically a channel full of oil. If the oil passage is blocked, it will affect your normal use and cause damage to the gearbox.

In one is to clean the body, if the body is very dirty, this transformation will produce frustration, and move slowly, car fuel, so choose 3 years or 60,000 kilometers in transmission oil, is your wise choice.

Automatic transmission works by hydraulic transmission, long-term operation will produce a lot of heat energy, transmission operating temperature exceeds 170 degrees, ATF oil gradually oxidizes and deteriorates at high temperatures, varnish sludge deposition and other working conditions are demanding, dirty transmission oil is more likely to aggravate the automatic wear between internal components.

As the vehicle's mileage increases, so do the data parameters of the automatic transmission itself. Changes in the mating clearance, coefficient of friction, system pressure and other factors between working parts will affect the normal operation of automatic transmissions.

If an automatic transmission is not regularly inspected and maintained, it can cause early damage to the automatic transmission.

Some car friends with improper operating habits, improper operation such as slamming on the accelerator, braking, neutral sliding, etc., will aggravate the wear and tear between the internal working parts, resulting in impurities such as iron filings and powder flowing with the oil, which may cause valve body jams, oil blockages and other failures.

In this case, the best thing to do is to change the transmission oil, remove impurities, and make sure that the interior is in good condition. Transmission maintenance is an important link, and it is also a maintenance link that we often overlook.

Many friends of the car know how to regularly maintain the oil, the engine is very important, and it is also the three major gearboxes, but some friends of the car pay attention until the problem costs a lot of money and regrets not realizing, therefore, it is very important to learn how to maintain the gearbox.

The gearbox of the car is a very important part, and regular maintenance and maintenance of the gearbox can make the car engine run better and avoid danger.

The reason is because the transmission is really very important, and once the transmission is damaged, we will be in danger when driving, and it is especially prone to car accidents, so it is necessary to maintain it.

This is because regular inspection and maintenance of the transmission can reduce breakdowns and wear and tear on internal parts, which can improve the life of the transmission.

Automatic oil circulation is based on mileage or maintenance time. If it is not specified in the vehicle manual, the transmission should be guided by mileage 60000-80000. During operation, relying on hydraulic transmission, long-term operation will generate a lot of heat energy.

Shift the transmission. When both oil change methods remain the same, the exchange rate is often checked for the oil level of the oil exchange rate and the oil exchange rate is changed periodically. Take Volkswagen models, for example:

Every 60,000 kilometers traveled, it needs to be equipped with automatic or manual trousers for maintenance.

Many car owners generally only know how to change accessories such as engine oil, three filters and a filter core, in fact, replacement is also one of the important parts of the car. Not only is it expensive, but it can also be expensive to maintain if something goes wrong. As a result, it is easy to keep the vehicle changing during daily driving.

There are only three things that need to be done well, but many people don't notice. One mastered the replacement. For many novices, the automatic transmission model is one of the biggest boon for motorists and one of the most intimate inventions.

Not only does it save you the hassle of start-up, but it also reduces shift work.

Especially for those novices who know almost nothing about the model, it is necessary to maintain and maintain the circulation of mobile transmission oil while driving an automatic transmission. Changing the transmission oil and strainer is easy over time. As a rule, it must be changed every 50,000 km or when the transmission oil is cloudy.

The internal control mechanism is very precise. If the transmission fluid is used for a long time, the pressure will be unstable. If not replaced in time, it will shorten the life of the oil and transmission parts.

Once there is a problem with the replacement, the repair will be very expensive. The licenses are small, so most don't require maintenance? The current design standard for double friction drives does not have long-term maintenance.

Car owners should not be deceived by 4S stores and stick to their bottom line. The common defects of the double clutch socks pure cloth transmission are gear shifting, timely maintenance, etc., which cause small defects of the automatic transmission to expand and deteriorate, resulting in serious accidents.

Do not use inferior transmission oil, because low-quality or counterfeit transmission oil has poor temperature resistance and is easy to oxidize, resulting in sludge and oil residue that clogs the filter, reduces the transmission oil pressure, and affects the quality of shifting. At the same time, the friction material and sealing rubber silver skin and metal parts are damaged, which eventually leads to the abnormal operation of the gearbox.

The recommended first service for automatic transmissions produced in Europe is 40,000 km or two years, and the second and subsequent maintenance is recommended at 20,000 km or two years.

In the process of long-term use of the car, all parts of the car will be lost, especially such as the transmission of this component, in the daily driving, frequent gear shifting, long-term high-speed operation, at this time the parts of the transmission will be due to wear and tear to reduce its performance, in order to make the performance of the car better, how should we maintain the transmission?

Regular inspection and timely replacement of transmission gear oil is the main measure, but manual transmission does not need to change gear oil before 100,000 kilometers of travel, and the general car needs to check the transmission oil for about 30,000 kilometers.

Because the transmission is very important in the car, so we must not take it seriously, if the gear oil in the transmission is lower than the normal line, then the gear is no longer lubricated. Moreover, without the protection of the oil film, the gear rotates at high speed, and the metal surface generates huge heat, which is easy to wear out the surface of the gear, and in serious cases, the surface of the gear will be ablated, so that the gear cannot rotate.

And different section of the field transmission oil will also affect the operation of the machinery, the general bridge manual transmission needs good adsorption, so the viscosity of many oils is relatively high, but too high viscosity will increase the resistance of gear operation, so we should choose a slightly higher quality when choosing gear oil.

If you feel that your car is in a similar situation but are not sure if it is caused by a transmission failure, we can determine the cause of the failure through a small grip test. First of all, we have to jack up the car or fix the car with cables and other items, and then start the vehicle, test the speed of the engine when the car is pressed to the bottom of the accelerator in different gears, if the speed of some gears is ridiculously high, it means that the corresponding gear clutch plate has slipped, which is the stall test method.

Don't underestimate this failure, the transmission problem is not a joke, as one of the three major parts of the car, it affects the normal driving of the car, so once you confirm that your car has a transmission slippage, you must send it for maintenance in time.

Usually go to the 4S shop for source maintenance, and then you also need to observe whether the engine and gearbox of the car are faulty, observe whether there will be oil leakage, and replace the antifreeze and oil regularly.

When the oil of the gearbox needs to be replaced, it should be replaced in time, and the correct oil should be replaced, and the gearbox should be replaced by a regular store. Kaiye.

I think it is important to change the transmission oil regularly and overhaul its components.

I feel that the transmission oil should be replaced regularly and its components should be inspected.

Cleaning and maintenance of gearboxes.

The car is cleaned and maintained once every 20,000 or 25,000 kilometers, or when the gearbox is slippery, the water temperature is high, the gear shift is slow, and the system leaks. Removes harmful sludge and varnish deposits, restores the elasticity of gaskets and O-rings, smooths transmission shifts, improves power delivery, and completely replaces old automatic transmission fluids.

Fold and change the oil and oil grid.

Change the engine oil and oil grid - after buying a used car, the first thing to change is to replace the engine oil, transmission oil, brake oil, water tank cooling water, etc. The oil must be changed at the same time as the oil grid, and it is also necessary to ensure that the oil circuit is not blocked by impurities.

Fold and change the transmission oil.

Changing Transmission Fluid – In general, transmission fluid is very easy to overlook, and consumers should change the transmission fluid after buying a used car that complies with the manufacturer's regulations, which is especially important for cars that are more than 5 years old.

One. Cleaning and maintenance of the fuel system.

Under normal circumstances, the car needs to be cleaned and maintained once every 10,000 to 15,000 kilometers, or when you find that the engine is shaking, sluggish and poor acceleration, black smoke, weak and fuel-efficient. Removes gum and carbon deposits from the inside of the system.

Two. In-depth maintenance of the lubrication system.

The main function of the lubrication system is to effectively lubricate the various parts of the automobile engine to prevent excessive wear and demand. Under normal circumstances, the car needs to be cleaned and maintained once every 5000 10000 kilometers, and it needs to be cleaned and maintained once when the engine noise is too loud, the acceleration is weak, and the water temperature is too high. Clean the sludge and other accumulations inside the engine to avoid oxidation thickening of the oil at high temperature, reduce the wear of engine parts, prolong the life of the engine, and improve the engine power.

Three. Cleaning and maintenance of cooling systems.

Under normal circumstances, the car should be cleaned and maintained once during the change of seasons in winter and summer, and cleaned and maintained once every 6 8 months during normal driving, or once when the water temperature is too high, leaking, and boiling. Remove traces and limescale that cause engine overheating, prevent harmful corrosion, avoid and stop leaks in seals and water tanks, and replace old coolant completely.

Four. Maintenance of the power steering system.

The car needs to be cleaned and maintained once every 40,000 45,000 kilometers, or in case of leakage of the steering difficulty system, after replacing the power steering parts, it must also be cleaned and maintained once.

Remove harmful sludge and paint film from the system, remove steering difficulties at low temperatures, stop and prevent leakage of power steering fluid, remove steering noise, and completely replace old brake steering fluid.

To understand the gearbox, we must first know that the gearbox is divided into two types: manual and automatic, and the manual gearbox is divided into two-shaft manual transmission and excitation center shaft manual transmission; There are four types of automatic transmissions, namely dual-clutch automatic transmissions (DCT transmissions), electronically controlled mechanical automatic transmissions (AMT transmissions), mechanical continuously variable automatic transmissions (CVT continuously variable transmissions) and hydraulic automatic transmissions (AT transmissions). How should the manual transmission be maintained, first of all, when driving to a certain number of kilometers or returning from a long-distance drive, be sure to check whether the gearbox has oil leakage and oil leakage, if so, be sure to clean and repair it in time. The lubricating oil in the gearbox should be replaced regularly, generally once every 100,000 kilometers.

For the gearbox, the transmission oil can play a role in lubrication, but if the transmission is used with mineral oil gear oil, the transmission oil needs to be changed every 3 years or 60,000 kilometers. If the owner is using synthetic oil, you only need to check the transmission oil regularly, if there is no problem with the transmission oil, you can temporarily do not change it until it is abnormal or when it comes to the regular replacement time, and finally, remember to keep the transmission clean.

In daily use, it is necessary to check whether the electrolyte of the car battery is sufficient, and check whether the wheels of the car are in normal use, which will affect the use of the car gearbox, and secondly, it is necessary to regularly replace the car's transmission dust tank oil to make the gearbox in the best condition.

The gearbox can change the rotation ratio of the car, which is composed of a transmission mechanism and a control mechanism, and the continuous development of science and technology makes the ordinary gearbox become the current continuously variable gearbox, so that the engine uses lower fuel consumption in the case of higher power. The transmission can be divided into automatic transmission and manual transmission, and the automatic transmission can be divided into continuously variable transmission royal car, dual-clutch transmission, etc., of which the single-speed transmission is generally the type of transmission used by electric vehicles. The car uses an automatic transmission that does not require manual gear shifting, and the car can automatically change gears through the change of speed.
