One of the more familiar may be the replacement of oil, glass water brake oil, antifreeze and so on, which is the most easily overlooked is the transmission oil.In addition to the fact that gearbox oil is expensive to change, the most important thing is that most people do not have the awareness to say that I want to change the gearbox oil, and some people even do not know how much time to change the gearbox oil, let's talk about some knowledge of gearbox oil.

Transmission oil is divided into two kinds according to the type of transmission, one is manual transmission and automatic transmission two kinds of oil.Usually gearbox oil has three functions. The first one must be heat dissipation.The gears work with each other, which is bound to generate a lot of heat, which needs lubricating oil for cooling.The second is lubrication, so that gear combination more smoothly.The third is to clean, keep the transmission system clean, extend the life of the transmission.

First of all, let's talk about how to distinguish the true and false transmission oil.In the maintenance of vehicles to replace the transmission oil, the first we want to put the transmission oil smell first, usually our transmission oil genuine case, it will have a burnt smell, the second is to see bubbles, genuine oil in the shaking is not to see bubbles, it can be said that there are few bubbles.

The third is to see the mobility of our transmission oil, genuine oil long after hanging on the wall of our bottles.The fourth is to see the viscosity, the real oil viscosity is very big, stick to the hand is not easy to remove, and can pull out the silk thread.

So how long does the transmission oil change once in the end, I believe many owners are not sure, in fact, there is no clear definition of this time, some people think that the transmission oil to be replaced regularly, 20,000 km, 40,000 km or 60,000 km as the boundary point, maintenance master is so said.Some people think that it is not necessary to replace the car, they have been driving for more than five years, driving more than 100,000 km without any problems, with experience to prove that frequent replacement is a waste.

First of all, we want to be clear, we change the transmission oil according to the model, different model requirements are not the same, many vehicles on the use of the manual clearly marked the transmission oil to often change, of course, some write lifelong maintenance free, so according to the actual judgment should not be changed.Under normal circumstances, automatic transmission oil is generally recommended to replace about 40,000 km once, the owner can judge whether to replace according to their own actual situation of the car.If the gears are very smooth and the transmission noise is not changing much, you don't need to replace them. 

Finally, the car gearbox is one of the three important parts in our vehicle, and the maintenance cost is relatively high.So the owner of the car in the car when you do not ignore the maintenance of the transmission, so the transmission we are not blind to the maintenance, not to say that we went to 4S shop or repair shop to do maintenance, listen to the master said your transmission to maintenance, you will go to maintenance.But according to the actual situation of some of the above mentioned xu for a more orderly maintenance, to have a certain ability to identify their own.
