How to change the automatic transmission oil a little better?

There are two specific ways to change it. One is gravity oil change, and the other is circulating machine oil change. Circulators are recommended for automatic transmissions. Change the oil thoroughly.

It's better to change the automatic transmission oil with the oil changer, my old Audi A4 used the gravity method for the first time, and it feels like the change is not very clean, and the PDK intelligent dynamic oil change is used in the back, and the sludge is discharged, and it feels thorough.

Hello, if it is an automatic transmission fluid change, it is better to use a cyclic oil change.

Changing the transmission oil generally needs to go to the repair shop or 4S shop to replace it, and the replacement by the circulating machine is relatively clean.

Hello, if the car replacement of this automatic transmission becomes too oily, I personally recommend using the reinforcing oil change method. However, it is relatively high and clean.

Hello, for automatic transmission oil, it depends on which automatic transmission you are equipped with, if it is AT, it will be better to use the circulation valve to replace it.

Hello, automatic transmission oil, generally use the circulation machine to replace it is more thorough, you can go directly to the repair shop to see.

The ways to change the oil of the automatic transmission generally include the oil change through gravity and the oil change of the switch.

1.Gravity oil change.

The definition of traditional gravity oil change is: using the gravity of ATF oil itself to drain oil.

Advantages of gravity oil change: use less new oil, and oil change is relatively cost-effective.

Disadvantages of gravity oil change: the manual static oil discharge method is not clean, and the oil in the oil pan can only be discharged, but at least the old oil in the gearbox remains in the gearbox.

2.Change the oil on the switch.

The definition of dynamic oil change of the switch is: the switch is used to circulate and clean the inside of the gearbox to bring out the old oil impurities in the gearbox.

Advantages of switch oil drain: dynamic oil change with intelligent switch can filter and cycle the oil sludge impurities in the automatic gearbox; Carry out equal exchange to ensure that the old oil in the gearbox can be completely replaced, and the internal circulation is cleaned, so that the gearbox has a good internal working environment and prolongs the life of the gearbox; Reduced fuel consumption.

Disadvantages of switch oil draining: more new oil is used, and the cost of oil change is high.

There are generally ways to change the oil in an automatic transmissionThe change is achieved by gravity oil change and switch oil change.

1. Gravity oil change.

Traditional gravity oil change is to use the gravity of ATF oil itself to drain oil. Advantages of gravity oil change: use less new oil, and oil change is relatively cost-effective.

Disadvantages of gravity oil change: the manual static oil discharge method is not clean, and the oil in the oil pan can only be discharged, but at least the old oil in the gearbox remains in the gearbox.

2. Change the oil of the switch.

Use the switch to circulate and clean the inside of the gearbox to bring out the old oil impurities in the gearbox. Advantages of switch oil drain: dynamic oil change with intelligent switch can filter and cycle the oil sludge impurities in the automatic gearbox; Carry out equal exchange to ensure that the old oil in the gearbox can be completely replaced, and the internal circulation is cleaned, so that the gearbox has a good internal working environment and prolongs the life of the gearbox; Reduced fuel consumption.

Disadvantages of switch oil draining: more new oil is used, and the cost of oil change is high.

Automatic transmission fluid change intervals.

Automatic transmission oil is generally 40,000 to replace once, due to the different gearbox design is divided into manual transmission and automatic transmission, the design of each gearbox has different technical requirements, even if the same model of transmission configuration in different models, the original factory has its own designated special gearbox oil. The change interval of transmission oil is longer than that of other oils, and some models are maintenance-free and do not need to be changed regularly unless there is a leak.

But you still need to go to the 4S store for inspection. If the oil is not changed for a long time, the transmission oil will become viscous, black, and smelly, and at the same time lead to greater fuel consumption, reduced power, machine failure, and will also block the filter due to dirty oil, so that the insufficient oil supply will cause the transmission to burn. Therefore, it is best for the owner to change the transmission oil regularly to make the lubrication and force transmission of the transmission more efficient.

After cleaning the oil pan, install a new automatic transmission filter element, install the oil pan and connect the circulating machine to replace the automatic transmission oil (12L new oil is required), and start the vehicle during the oil change process of the circulating machine. At this point, the new oil is injected into the automatic transmission, and the old oil is pushed out by the pressure.

In the process of changing the circulating machine, the alternation of new and old oil is like doing hemodialysis, and the alternation of new and old oil can be clearly seen through the window window, and the color of the old oil window gradually changes from dark black to red, until the color of the new and old oil is consistent. The cycle time is about 10 minutes, and the oil change process takes about 90 minutes, which is half the time of the original gravity oil change method, and a total of 12 liters of automatic transmission oil is required. After the car has changed the oil, you have to go out for a run, and then open the observation hole in the state of the car, and release the excess oil to avoid the oil position being too high.

There are two specific ways to change it. One is gravity oil change, and the other is circulating machine oil change. Circulators are recommended for automatic transmissions. Change the oil thoroughly.

There are two ways to change the oil, one is to change the circulating machine, and the other is to directly remove the screws and drain the oil, relatively speaking, the circulating machine oil change is relatively clean [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

There are two ways to change the oil of the automatic transmission, one is the gravity oil change method, and the other is the circulating machine oil change method. The gravity oil change method is very simple, you need to lift the car lift, the gearbox is generally under the engine, remove the gearbox guard, and see a square box, which is the oil pan of the gearbox, and you can release the oil by unscrewing the oil drain screw of the gearbox oil pan.

The old gearbox oil is released from this screw mouth, and it is best to collect the old oil in a container below before the oil is released, so that you can know how much oil is put out, and you have a bottom when adding new oil, and it is also environmentally friendly. The circulating oil change method is a bit more complicated and requires the use of a circulating machine and a little more new transmission oil.

Automatic transmission oil generally needs to be replaced at around 80,000 kilometers. Gravity oil changes are cheaper, but gravity oil changes can only release 60 to 70 percent of the old transmission oil, so gravity oil changes are not particularly clean. The recirculating machine oil change is much cleaner, and this method of oil change can release about 90% more of the old transmission oil.

However, the oil change of the circulating machine is more expensive and the operation is more complicated.

How should an automatic transmission change the oil.

1. There are two ways to change the transmission oil for automatic transmission, gravity and circulation machine replacement.

2. Gravity oil change, that is, lift the car, unscrew the oil screw, and add as much oil as you want, generally about 5 liters. The premise of gravity oil change is that it is best that your last oil is the same as this one.

3. The oil change of the circulating machine is to replace the transmission oil in the starting state of the car, at this time, the oil flows internally, which will bring out the dirty things in the gearbox, generally about 12 liters, and the oil change method of the circulating machine is clean and thorough.

4. The oil change of the circulating machine is cleaner than the specific gravity, and the oil change of the automatic transmission is recommended to be cycled. Of course, if the car usually changes the oil diligently and there is no fault problem, it can be changed by gravity.

The viscosity of the transmission oil that has been used for a long time will become thinner, resulting in a decrease in lubrication performance, a decrease in sealing performance, an increase in resistance, and an increase in wear, resulting in unstable pressure and affecting the working accuracy of the hydraulic system. The transmission control accuracy decreases, the shift accuracy decreases, the ride and response speed will be affected, the oil cooling performance and anti-oxidation performance after deterioration will decrease, and it is easy to produce problems such as excessive oil temperature, a vicious circle, and further shorten the life of oil and transmission parts. Many automatic transmission failures are caused by untimely oil change or improper oil change methods, and more than 90% of automatic transmission failures are caused by overheating and transmission fluid that has not been replaced for a long time, resulting in impurities.

Generally speaking, the replacement period of automatic transmission oil is recommended by car manufacturers at about 6-80,000 kilometers or 2-3 years (4S shops will recommend shortening the replacement mileage), and vehicles with more high-speed driving are recommended to be replaced once at about 40,000 kilometers, and some cars claim to be free of replacement for life. But Lao Hou does not agree with this point of view: as long as it is mechanical, there will be wear, the lubricating oil will definitely become dirty, the lubrication effect will become worse, and it must be replaced after a certain cycle.

One of the claims to be maintenance-free for life is that the manufacturer has a weak sense of responsibility, and the other is the manufacturer's definition of "lifelong". For example, the BMW transmission claims to be replaceable, but its "lifetime" means ten years or 150,000 kilometers. It doesn't think most people will drive their cars for that long.

How to replace the automatic transmission.

At present, there are three mainstream methods to replace the automatic transmission, the first is similar to the way of changing the oil, by unscrewing the oil drain screw of the gearbox to drain the oil and fill, and the second is to directly remove the oil pan for oil drain and filling. These two methods are often referred to as gravity oil changes.

Because there are torque converters, clutches, brakes, valve bodies and radiators in the automatic transmission, etc., a large amount of transmission oil is stored in these parts, even if the car is stopped and the engine is stopped, the oil will not flow back into the oil pan, so by unscrewing the oil drain screw under the gearbox, manually draining the oil or disassembling the transmission oil pan can only replace about half of the waste oil in the gearbox, and the replacement is not only incomplete but also leads to the contamination of the new oil. If the gravity oil change method is used, it will take two to three changes in a short period of time to change the fluid in the transmission, and the next oil change interval will also be advanced.

There are two ways to change the transmission oil, gravity oil change and circulating machine oil change

1. The advantage of gravity oil change is that it is economical and simple to operate, and the general vehicle needs 45 liters of transmission oil. The disadvantages are obvious: because of the structure of the gearbox, the static oil change method under normal pressure or disturbance will cause about 49% of the transmission oil to not be discharged from the gearbox, and the transmission oil change is not clean;

2. The oil change rate of 70 can be achieved by disassembling the oil pan by disassembling the oil pan, which can actually ensure the health of the gearbox;

3. Automatic gearbox, gravity oil change can be used, but the method of oil change of the circulating machine is recommended, the disadvantage of the oil discharge of the circulating machine is that the transmission oil required is more likely to lead to the rise of maintenance costs, but the oil change rate is as high as 90 or more.

It is best to go to a 4S shop or repair shop to change the automatic transmission oil:

1. There are generally two ways to change the transmission oil, gravity oil change and circulating machine oil change. The advantage of gravity oil change is that it is economical and simple to operate, and the general vehicle needs 45 liters of transmission oil;

2. The shortcomings are obvious: because of the structure of the gearbox, the static oil change method under atmospheric pressure will cause about 49% of the transmission oil to not be discharged from the gearbox, and the transmission oil is not clean, almost half can only be replaced;

3. For automatic transmission, gravity oil change can also be used, but the method of oil change of the circulating machine is recommended, and the disadvantage of the oil discharge of the circulating machine is that more gearbox oil is needed, and the general vehicle needs 1012 liters, which leads to the rise of maintenance costs, and the time of oil change of the circulating machine is also relatively longer than that of the oil change of gravity.

2. The shortcomings are obvious: because of the structure of the gearbox, the method of static oil change under normal pressure will cause about 49% of the gearbox oil to not be able to discharge the gearbox, and the gearbox oil change is actually not dry and clean, almost half can only be replaced;

4. General vehicles need 10-12 liters, which leads to the rise of maintenance costs, and the oil change time of the circulating machine is relatively longer than that of gravity force oil change.
