How to maintain the automatic transmission?

1. According to the requirements of the original factory, check the transmission oil regularly, replace the transmission oil on time, and use the transmission oil specified by the original factory.

2. The oil released through the oil drain bolt only accounts for about 30% of the total oil volume, and it is not recommended to use transmission cleaning agent in this case.

3. If the transmission oil is completely replaced, the transmission cleaning agent should be used in conjunction with the transmission oil exchange. Before the old oil is drained, the detergent is poured into the gearbox, the drive wheels are suspended, and after the car is landed, the detergent is constantly shifted so that all interior areas can be cleaned. At the end of the cleaning, use a switch to drain the old oil while filling in the new one.

Finally, replace the filter.

4. If the automatic gearbox is not dismantled and cleaned, there are many precautions when operating, if incorrect products and fake and shoddy products are used, or improper operation, it is easy to lead to accidents, and serious may lead to damage to the gearbox, so be sure to use formal channels and products of well-known enterprises in qualified service providers to ensure the safety of the gearbox and their own rights and interests, such as 3M, BG, WYNN'S and other brands.

The effective method of deepening the maintenance project of Aofu transmission system is as follows: dynamic oil change, the use of special gearbox cleaning equipment, in the process of transmission operation, the old oil is fully circulated, and the automatic transmission system efficient cleaning agent is added when changing the oil, so that the product can safely and effectively remove the sludge, gum and other deposits in the system, prevent the wear of the parts, and ensure a good oil change effect. At the same time, in order to improve the antioxidant stability of automatic transmission oil and prevent deterioration; Improve the lubrication effect, reduce friction and anti-wear, flat-vibration and noise reduction, maintain the smoothness of work, add a strong protective agent for the automatic transmission system, safely and effectively improve the performance of ATF fluid, improve the working state of the system, and prolong the service life of the parts.

According to Bian Xiao, many friends don't know much about some car knowledge. In order to facilitate everyone to understand this knowledge, today Bian Xiao will introduce to you how to maintain the automatic transmission. Interested friends can learn about this problem, which may be helpful to you.

The maintenance of automatic transmissions should be done well, such as regular maintenance of transmission oil and reasonable use of regular transmission cleaning agents. Automatic transmission maintenance refers to the maintenance conditions required for the car to be made of local materials. It is a new process to use special care materials and products with different properties to maintain and care for automotive automatic transmissions.

An automatic transmission (AT) is a device used in automobiles that automatically functions as a clutch and transmission. It automatically transmits and disconnects engine power, automatically changing the speed and gear ratio to power the drive wheels. Now it is widely used in various brands of cars.

How to maintain an automatic transmission?

1.Follow the requirements of the original factory, regularly maintain the transmission oil, change the transmission oil on time, and use the transmission oil of the original specified number.

2.The oil released by the drain bolt only accounts for about 30% of the total oil volume. The use of transmission cleaners is not recommended in this case.

3.If the transmission fluid is completely replaced, the transmission cleaner should be used with the transmission oil exchanger. Before draining the old oil, pour the cleaning agent into the gearbox and the drive wheels are suspended.

Once on the ground, the cleaner can clean all interior areas by constantly changing gears. After washing, use the switch to drain the old oil while filling in the new one. Finally, replace the filter.

4.If an automatic transmission is cleaned without dismantling it, there are many things that need to be paid attention to when operating. If you use defective products and counterfeit and shoddy products, or improper operation, it is easy to affect the accident, and seriously affect the damage of the transmission.

Therefore, it is necessary to use the products of well-known enterprises in formal channels at qualified service providers to ensure transmission safety and their own rights and interests. In addition, when using the car, it is necessary to pay attention to prevent skidding in neutral gear, prevent the drive wheels from rolling on the ground when pulling the car, and prevent the car from hanging forward gear for a long time and pressing the brakes at the same time.

1.Follow the requirements of the original factory, maintain the transmission oil regularly, change the transmission oil on time, and use the transmission oil specified by the original manufacturer.

2.The oil released through the drain bolt is only about 30% of the total oil, and it is not recommended to use a transmission cleaner in this case.

3.If the transmission oil is completely changed, the transmission cleaner should be used with the transmission oil exchanger. Before draining the old oil, pour the cleaning agent into the gearbox and drive the wheels to hang up.

Once the car is parked, the cleaner can clean all the interior areas by changing gears continuously. After cleaning, use the switch to drain the old oil air and inject new oil at the same time. Finally, replace the filter.

4.If you do a good job of automatic transmission disassembly-free cleaning, you should pay more attention when operating. If you use bad products, fake and shoddy products, or improper operation, it is easy to affect the accident and may seriously affect the damage of the gearbox.

Therefore, it is necessary to use formal channels and products of well-known enterprises in qualified service providers to ensure the safety of the gearbox and their own rights and interests, such as 3M, BG, Wynn and other brands.

Accessory: Signs of Gearbox Failure:

1.Transmission slippage:

During driving, if the sound of the engine idling is heard while refueling, and at the same time the car does not have a clear acceleration and a weak acceleration; Or you can't go uphill, the engine speed is inexplicably high, and the road is mostly normal, then be careful.

2.Transmission oil leakage:

I could clearly feel that the car was hard to start. While the speed at which you press the gas pedal increases while driving, the car doesn't have a noticeable sense of acceleration. The culprit could be an oil spill.

Oil leakage will affect the internal lubrication of the gearbox, and the gearbox will not work properly. This situation is quite simple compared to the same period last year, just change the transmission oil.

3.There is noise in the gearbox:

This symptom is that in the process of driving the car, the gearbox has an inexplicable sound, and the specific sound cannot be detected**, and even very loud noise, and there is a sound when switching gears, and it is very dull. The reason for the sound of the gearbox is complex, and it may be due to the reduction of the anti-wear performance and lubrication performance of the transmission oil under long-term high temperatures, and the wear or damage of bearings, gears and other components.

<> "The automatic transmission of the car is already a must-have equipment for many cars. The internal control mechanism of the automatic transmission is very precise and the clearance is small, so most manufacturers recommend that the oil change interval of the automatic transmission is generally two years or 4 60,000 kilometers. In the process of normal use, the working temperature of transmission oil is generally around 120 degrees Celsius, so the quality of the oil is very demanding, and it must also be kept clean.

Secondly, the transmission oil will produce oil scale after being used for a long time, which may form sludge, which will increase the wear of various friction plates and components, and also affect the oil pressure of the wild sound system, so that the power transmission will be affected. Thirdly, the sludge in the dirty oil will make the movement of the valve body in each valve body not smooth, and the oil pressure control will be affected, so that the automatic transmission will be abnormal.

Good daily maintenance is very necessary for automatic transmissions.

1.The engine can only be started when the gear lever is in the P or N position, and if you want to move out of either gear with the ignition on, you must press the brake pedal and press the lever at the same time.

2.Vehicles equipped with automatic transmissions cannot be started by traction starting. Due to the flexible connection between the torque converter and the engine, the gearbox cannot be reversed and the shaft rotates.

3.The gear lever is placed in n gear; The towing speed is less than 50 kilometers per hour and the distance is less than 50 kilometers; If long-distance traction is required, the driving wheels should be placed on the tractor; Do not lift the non-driving wheels to the vehicle and tow it backwards; At this time, because the oil pump does not supply oil, the inside of the gearbox is not fully lubricated, and the reverse towing will cause the internal mechanism to rotate at high speed, resulting in serious damage to the inside of the gearbox.

The gear can be used as an auxiliary brake for the hand brake, but not as a substitute for the hand brake; The gear lever should be placed in P gear for long stops, and the hand brake must be pulled up.

5.If you stop for a short time while driving, you can put it in D gear and press the brake pedal at the same time; It is not necessary to shift into P gear.

6.When starting in a very cold winter day, you should give a minute to warm up before starting to drive.

7.When the vehicle is running normally, select D gear when moving forward and R gear when reversing; Under special circumstances, the gear lever can only be pushed from low to high in driving, until D gear, and it is strictly forbidden to pull from high to low.

8.It is strictly forbidden to coast in neutral gear while driving, otherwise it will cause serious damage to the gearbox.

9.In case of gearbox bump and oil leakage, abnormal driving and relevant warning lights on during driving, you must stop using it immediately and contact the service station to inquire about the handling measures.

10.The transmission oil and filter element must be replaced in a timely manner according to the mileage and time specified by the manufacturer.

1. Damage to the cooling system of the engine and automatic transmission will lead to problems such as high ATF oil temperature, premature deterioration, aging and failure of internal seals, thereby shortening the service life of the automatic transmission. 2. The oil change interval of the gearbox is generally 2-40,000 kilometers, about two years. 3. If your car does not accelerate at the start, does not go away, delays in gearing, impact of shifting, frustration in driving, or abnormal noise and odor, etc., it may be that there is a problem with the automatic transmission, and you need to diagnose and repair it in time to prevent the fault from expanding!

4. Automatic transmission special oil is referred to as ATF, its quality directly affects the service life of automatic transmission, oil change maintenance must choose a professional maintenance manufacturer, use high-quality ATF, and the selected ATF model should match the automatic transmission. 5. When the electronic control system of the automatic transmission fails, the warning light on the dashboard will be on, which is the precursor of the problem of the automatic transmission, and it should be checked in time to the repair factory to eliminate the problem.

Check the maintenance manual of the vehicle, refer to the mileage for maintenance, and don't listen to the 4S shop.

The main thing is to carry out regular maintenance, to avoid the cheap use of low-end or fake oil, automatic transmission about 60,000 kilometers need to be replaced with oil, to avoid violent driving during use, these will delay the rapid aging of the internal parts of the gearbox.

Just follow the maintenance manual.

1.Check the transmission oil regularly according to the original factory requirements.

2.Transmission cleaners are not recommended.

3.If you want to clean the gearbox without dismantling, it is recommended to go to a 4S store.
