How often is the transmission oil changed?

The gearbox, chassis, and engine car are all known, but the doorways in the auto repair industry are understood, and the laymen who do not understand the routines are frequently pitted.

For example, in order to overcharge the owner of the car, some repair shops often tell the owner to change the transmission oil for 20,000 kilometers, and each time the transmission oil is replaced, it will waste about 800 yuan. But the fact is that the gearbox oil is too diligent to change is useless, the oil poured in last time has not been lubricated before it is replaced, and frequent replacement of transmission oil is not only a waste of money but also a lot of effort.

So the question is, since you don't have to change it often, how often is it appropriate to change it?

Because the replacement cycle of motor vehicle transmission oil because of the difference in model and design requirements, there is no unified standard for replacement time, the most accurate way is to look at the maintenance manual of your own car, if the vehicle manual clearly gives the replacement mileage or use time, you can implement it according to the standard.

If you do not have such indicators in your vehicle maintenance manual or accidentally lose the manual, you can refer to this standard to determine the oil change time according to the gearbox type:

Manual transmission is recommended for 3 years or 50,000 km to change transmission oil

AT transmission is recommended for 3 years or 60,000 km to change transmission oil

The CVT and DSG dual-clutch transmissions recommend oil changes once every 4 years or 80,000 km

If you feel that the hanging gear is jerky when driving, the cold start is weak, it is easy to slip, that is, the mileage is not reached, at this time, you should also check whether you need to replace the transmission oil.

The price of transmission oil is not cheap, the price of automatic transmission oil is about 80 yuan a liter, some car owners are greedy and cheap, using very low price transmission oil, this type of transmission oil may be counterfeit and inferior products, not only can not play the role of heat dissipation lubrication, but also lead to serious wear of parts.

How to distinguish between real and fake oils:

1, smell the oil: genuine oil has a scorched smell;

2, look at the fluidity of oil: after the genuine oil "hanging bottle", it is not clean for a long time;

3, look at the bubbles of the oil: after the genuine oil shakes, it is rare to see bubbles;

4, look at the viscosity of the oil: genuine oil is not easy to remove from the hand, can be drawn.

Many riders reflect that every time they do maintenance, they always recommend changing the transmission oil, changing as little as 800 pieces at a time, and going back and forth several times is also a few thousand. At this time, there are some doorways you should pay attention to.

Most of the general riders choose to replace the transmission oil in the 4S shop, because the 4S shop will use the original shift fuel tank, of course, if the repair shop is replaced, the owner needs to pay attention to the problem of the transmission oil number. In addition, the method of replacing the gearbox is also very critical, and many times the gearbox oil is not clean, which still has a great impact on future use.
