Transmission lubrication, as well as engine lubrication, is divided into three types: mineral, synthetic and semi-synthetic.
Even experienced motorists are sometimes misled that the addition of synthetic grease in the mineral, the output will be a semisynthetic cocktail, which also does not depend on the manufacturer. So it turns out that it is possible to mix absolutely any oil? But this is an absurd statement. We advise you not to even try to experiment in this way, but rather to listen to experts. Such mixing promotes foam formation, and after half a thousand kilometers there is still precipitation in the form of the same whitish flakes. And when the path is doubled, the sediment becomes a thickening substance that clogs up all the possible openings and the whole system. In addition to all this, the seals can also be squeezed out. To get rid of this, you will need to completely remove the unsuitable composition and thoroughly rinse the entire system, and then fill the new material, which is recommended by the manufacturer for the transmission of your car. This information is usually placed in the service book or on the official website of the company. We kindly ask you not to engage in amateur activities. So, let's sum up the results concerning all the above mentioned. It is not necessary to mix transmission oils from different manufacturers, let who and what would you say, because it can adversely affect the further work of the transmission of your car. Yes, even if in the gearbox and there are no such extreme temperature phenomena as in the internal combustion engine, but there are a high-precision mechanics and electronics, which, especially in the box, to disable very simply such a refill. However, the mixing of transmission oils is allowed in emergency cases. For example, if you are on the way far from the city, and the system gave a leak, then in order for the car to reach the nearest service or to its garage, you can conduct such a procedure. But to avoid more serious problems, at least follow the oil markings. Upon arrival at the place, it will be necessary to completely replace the transmission fluid to the proper one and wash the gearbox.
If there are strange noises in the gearbox
During the operating process of the gearbox, moisture droplets and metal particles that break off from the gears as a result of wear and tear get into the gearbox. This leads to a loss of quality and function of the box. To prevent further problems, listen to the gearbox for strange sounds that have not been noticed before. It can be grinding and buzzing and a terrible howl.
During the diagnosis, the oil has become too dark with a characteristic scent of burning
To be completely confident, inspect the transmission oil with a dipstick to check the level. If it's black and smells like garbage, then immediately replace the transmission lubricant.
Depending on the distance traveled. The vehicle manufacturer and operating conditions vary the timing of the transmission oil change. Some experts advise replacing the transmission oil after about 40 thousand kilometers, others - 60 000 kilometers.
There is also the practice of replacing transmission oil even after 13,000 kilometers. Remember that although the gearbox is a fairly stable system of the car, to change the oil every 60 000 kilometers will be the best option. This is the recommendation of most experienced professionals. When buying a used car, immediately replace the oil in it, because there is no certainty that the previous owner changed it correctly and regularly.
