When does the transmission fluid need to be changed? What to look out for?

Do I need to do four-wheel alignment to change the steering machine? The auto repair master is experienced and talked about the precautions!

Transmission fluid needs to be changed when it is necessary to change lanes, acceleration, you should pay attention to the vehicles coming and going on the road, and whether the performance of the engine can withstand a series of things.

If we have traveled 4 60,000 kilometers, or if we find that the fuel consumption is particularly high and the acceleration is slow, then the oil in the transmission oil should be changed at this time. Note that you must choose the right oil for your car, try to buy some of the original **, avoid damaging the gearbox, don't be greedy for a small bargain, buy some inferior oil, so as not to reduce the service life of your car.

The transmission oil needs to be replaced. Different models are equipped with different types of transmissions, and the replacement intervals are also different. It is generally recommended to change the manual transmission oil of the car every three years or about 100,000 kilometers, the automatic transmission oil is generally recommended to be changed every two years or about 40,000 kilometers, and the continuously variable transmission oil is generally recommended to be changed every two years or about 60,000 kilometers.

If it is not replaced for a long time, the viscosity will be reduced, and the sealing performance will also be reduced, which will affect the lubrication effect of the transmission oil, thereby affecting the work of the hydraulic system, resulting in unstable pressure of the automobile gearbox, unsmooth manual shifting, and affecting the operation of the car.

Gearbox maintenance methods include:

1. Regular oil change of gearbox;

2.Check the oil level frequently;

3.Don't coast in neutral;

4.Leapfrog and upshift;

5.Don't force the gap;

6.Minimize the idle time of hot cars;

7. Avoid gear teeth;

8.Clean the gearbox.

Here are the steps to change the transmission oil:

1.Prepare wrenches, including socket wrenches or torx wrenches, generally 14mm, 17mm, 19mm, 21mm, 24mm wrenches, and some square screws.

2.Unscrew the screws of the viewing hole.

3.Unscrew the drain screw and drain the transmission oil.

4.The car has a front pressure box and a rear pressure box, both of which are drained.

5.Screw on the oil drain screws.

6.Pour the gearbox into the pressure box barrel and use the pressure tank oil filling tool to inject the oil pressure into the gearbox.

7.Until the viewing hole reveals the gearbox, it's okay.

8.Tighten the sight hole screws to complete the installation.

The transmission oil of the car must need to be changed, and after a long time, it should be cleaned and replaced, if you want to replace it, you should first use an oil pipe, pump out all the oil or drive directly, and then pour some cleaning liquid to clean it.

It needs to be replaced, and there will be problems when the car transmission oil is used for a long time, and timely replacement can make the car run normally. Find the car gearbox, then unscrew the lid on the gearbox, pull out the oil inside, and then put in new oil.

Car transmission oil needs to be replaced, if not changed often, the transmission oil will deteriorate, which will affect the normal use of the car, you can find a 4S shop or find a repair shop to replace.

It must be selected in strict accordance with the requirements, otherwise it will reduce the service life of the gear unit and even cause early damage. High-quality brand automotive transmission oil can not only effectively protect gears, reduce wear, make the vehicle easier to run, and save fuel, but also prolong the service life of oil products and reduce maintenance and repair costs. When changing the transmission fluid, the automatic transmission fluid specified by the manufacturer must be changed.

<> this is due to the fact that different automatic transmissions have different internal structures, friction parts, and sealing parts. **Specially formulated according to the structure and material of the transmission. It doesn't matter how good the quality of other brands of oil is.

There will be residual oil in the transmission fluid. If different oils are added, the two oils will mix automatically, causing failures such as poor lubrication or abnormal working of the automatic transmission, or even damage to the automatic transmission.

In order to prevent tooth flank wear, spalling and sintering caused by gear contact forces, it is essential to select a transmission oil with good anti-wear and extreme pressure properties to maintain proper load-bearing capacity. Therefore, when choosing engine oil, users should not add internal combustion engine oil, hydraulic oil and other engine oils to the gearbox, so as not to cause insufficient extreme pressure anti-wear performance and damage to the gears. If the viscosity is too large, it will overheat the friction surface, which will cause unnecessary rough punching power loss, if the viscosity is too small, due to the action of centrifugal force, the oil will flow out of the tooth surface groove, which is easy to cause oil seal leakage, which may form boundary lubrication and wear on the surface of the gear, and even produce sintering phenomenon, so it is very important to choose the right viscosity.

Do a detailed explanation of the problem to do a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also rent to follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

The precautions are to pay attention to the replacement method, pay attention to your posture, pay attention to the protection of the car, and do not damage the engine or the appearance of the gearbox. Of course, I know that if there is damage to the engine and gearbox during the replacement process, it will lead to the scrapping of the car, and it will also lead to the failure of the car.

It should be noted that when the engine is turned off, it can only be replaced after the change is buried or the gearbox becomes cold, when changing the gearbox oil, it should be noted that its oiler hole is at the bottom of the gearbox, and the oil that meets the specifications should be used, and the shell of the gearbox should be checked for broken fiber after installing the plug, and at the same time, the old oil should be leaked and replaced with new oil when changing the oil.

The engine needs to be turned off, the training needs to be replaced on the flat ground, and the oil level needs to be checked in advance, so that it can be better replaced, and we must pay attention to the choice of brand. acres buried.

<> "A car cannot be without transmission oil, and the existence of transmission oil plays a role in keeping the transmission system in a clean state, and can also extend the service life of the transmission. So when should you change the transmission oil?

If the transmission oil deteriorates, darkens in color, sticky, smells, etc., it needs to be replaced immediately. Of course, it is difficult for many car owners to perceive the above conditions, if the gearbox often appears when the vehicle is moving, the gearbox often has a shift impact, skidding, acceleration weakness, abnormal noise, etc., it is recommended to change the fiber transmission oil.

Transmission oil can be divided into automatic transmission oil and manual transmission oil, manual transmission oil replacement cycle can be slightly longer than automatic transmission oil, can be controlled at 6-80,000 kilometers to change once.

However, if the owner does not change the transmission oil for a long time, then there is a great possibility that the life of the transmission system cannot be further extended. In general, it is best for car owners to change the transmission oil at the right time to prevent unnecessary trouble.
