Why do the automatic transmissions of some new Chinese cars need to be changed immediately?
It is no secret that technical fluids used in modern cars are selected in accordance with specific criteria and indicators, including those related to the conditions of their practical operation. But do Chinese cars always meet these requirements? The Avtovzglyad portal has found the answer to this question.

Let’s immediately make a reservation – the topic discussed in this material mainly concerns “heavenly” cars that come to us through unofficial channels, for example, privately imported or through a “gray” supply chain. We will talk about problems with variators or “robots” that arise during their winter operation.

We remind you that transmission oils recommended for our automatic transmission market must have a pour point not higher than −48°C. However, in the Middle Kingdom, the majority of cars produced are used at more moderate temperatures. As a result, working fluids corresponding to milder climatic conditions are poured into “automatic machines” there on conveyor belts. At low temperatures, such compositions can completely lose their fluidity as early as −35°C.

It is clear that under the conditions of our country, where in many regions frosts above thirty in winter are common, such an “automatic machine” will certainly break down. In fact, this is what the owners of a number of “Chinese” unofficially imported into Russia are already dealing with. Additionally, over time, this can cause much more serious problems with the automatic transmission.

Experts note that the viscosity of the “wrong” CVT fluid rises to a critically high value even at 20 degrees below zero, and this can most likely lead to failure of transmission components. Meanwhile, many owners of “Chinese” vehicles equipped with “automatic machines” are completely unaware of these nuances. As a result, their operation in the winter cold often occurs under extreme conditions, when the viscosity of the fluid is much higher than the standard viscosity.

The negative consequences of such actions will quickly manifest themselves. So, with CVTs, shifting may be slower, and with “robots” there may be jerking and slipping of the clutch, accompanied by a characteristic odor. In any case, all this clearly leads to accelerated wear of the automatic transmission.

What conclusion follows from the above? It is clear that when buying a Chinese car imported via the “left” route, you should carefully study the characteristics of the fluids and lubricants recommended for it, including automatic transmission oil. If the freezing temperature does not correspond to the value indicated above, it is advisable to change such “transmission”.

As for choosing a suitable product for the “automatic machine”, today there are no problems with it. Take, for example, the products of the Turkish brand Lubex, under which a wide range of lubricants, including transmission oils, are supplied to Russia. Their range also includes such a popular product as the synthetic fluid Mitras CVT, which is specially designed for CVTs.

As experts note, this composition is distinguished by excellent performance at low temperatures and versatility in use. Suffice it to say that Mitras CVT from Lubex is suitable for any modification of a CVT automatic transmission, which is equipped not only with Chinese, but also with many other cars from the USA, Japan, South Korea and European countries.
