Transmyssyonnoe oil - is Special type of oil kotoroe Created for use in hydrousylytelyah rulevoho management, razdatochnыh boxes, gears, axles, mechanical and of automatic transmissions. The main thing Requirements for transmyssyonnomu oil zakljuchaetsja in abilities and made the uderzhyvat on the surface of parts transmyssyy maslyanuyu plёnku, kotoraja will be vыderzhyvat High load, sozdavaemыe in the process of work equipment.
Transmission oil marking
By marking the transmission oil it is possible to outrun mineral oil or synthetic, the correspondence of this oil with the quality standards, its SAE viscosity and many other characteristics. For example: ATF, Dextron and Dexron inform that this gear oil is intended for automatic gearboxes. This is due to the fact that neither automatic transmissions nor motor oil can be used for ACP. The oil marked ATF, which is decoded as Automatic Transmission Fluid, has a low viscosity and is applied exclusively in automatic gearboxes.
Below, in the article, we will consider the main indicators presented on the labels and accompanying documents when describing the properties of transmission oils.
Transmission oil API characteristics
The API parameter characterizes the performance characteristics of the transmission oil, such as the type of oil and its scope, is indicated by the letters "GL" with a number from one to five:
•    GL-1 - mineral oil without any additives affecting its properties;
•    GL-2 - oil in the composition of which there are fat components, such oil is used in industrial equipment and worm gear types;
•    GL-3 - oil has anti-drain additives, used in rear axles, mechanical and helical-conical gearboxes;
•    GL-4 - in addition to anti-closure, it also contains anti-wear and a number of other additives, used in spiral-conical and manual transmissions;
•    GL-5 - has a large set of additives among which are prototype and anti-perceptual, used in hypoid and a number of other transmissions.
Applicability of transmission oil
The use of this or that type of oil directly depends on the requirements of the manufacturer of special equipment. Therefore, we encourage you to adhere to the requirements specified in the instructions for use and not to use oil with a lower API level. Let's consider the general principles of application of gear oil depending on the indicator "GL".
In most cases, GL 3 oil is required for the transmission of trucks (without hypoid gears), but in some cases GL 5 oil is used for check points and bridges of some machines.
In passenger cars and hruzovыh ymeyuschyh reduction gears with hypoydnыm way stseplenyya shesterёnok prymenyayut oil GL 5.
This with topics such oil something pomozhet avoided zadirov appearance on zubyah gears.
In the transmission of passenger cars it is customary to use GL 4 oil for mechanical gearboxes and GL 5 oil for lubrication of driving bridges
SAE Transmission Oil Performance
The parameter SAE (viscosity class) characterizes changes in the viscosity of the oil at different temperatures and allows you to split the gear oils into three categories:
• Winter oil - SAE 75W-90 works great in the cold season (with the letter W in the marking);
• summer oil - SAE 140 and 250, used in warmer seasons or in countries with hot climates; in temperate climates, it is desirable to use oil of class 90 (W in the absence of marking);
• vsesezonnoe Oil - SAE 75W-90, 80W-90 and 85W-90 and acknowledged unyversalnыm Using podhodyt for year-round (and letnyaya zymnyaya labeling pyshetsya through defys).
