Do I need to change the oil in the gearbox?
Mechanics, automatic, CVT - what and how often to change the oil in these transmissions.
The list of works on any car maintenance included changing the engine oil. But we should not forget that the gearbox is also filled with oil. But how to determine that it is time to replace it? Does it fade time work and whether it should be topped up as the engine? And is there a time limit for service driveline?
🔎 Why oil in a box
Any oil, even for engines, even for transmissions consist of a base, the so-called base oil and additive package.
In these thermal loads butter begins to foam and lose lubricity
Properties of oils are determined by the quality of the chemical composition of their base and additives added to the oil used to adjust and improve their performance.
Apart from the lubrication of gear oils have another important function, it is the removal of heat from the meshing gears. The average temperature of the oil in the gearbox of a vehicle in motion is around 150 degrees Celsius, and at the contact patch meshed gears - about 300. When the temperature of the oil begins to foam loads and lose lubricity. In automatic transmissions oil is also a working body, transmitting the torque from the engine to the gears and foamed oil just does not allow the machine to move. It does not help even a special radiators mounted to cool the oil. To avoid this, add the oil in a special additive package.
🔎 When and Why change the oil?
The oil must be changed, primarily because of the loss of efficiency additive package. With the passage of time during the operation additives lose their properties and cease to provide reliable protection of working surfaces. Oil starts to foam and can occur bullies final drive. Consequences - boring buzz differential gear transmission, which will be amplified, and after 300-500 kilometers gear teeth begin to fail. Eventually the gearbox jammed. This is for vehicles with front-wheel drive and full. On vehicles having rear-wheel drive and manual transmission, the gearbox does not feel such temperature loads and oil can serve 10-20 thousand for longer without losing the lubricating properties. But his replacement is usually timed to changing the oil in the gearbox. This is done to remove dirt and chip, which is produced as a result of the gears, and replacing exits the transaxle housing with the oil overflows.
To avoid this, manufacturers recommend to carry out the procedure for replacing the gearbox oil every 50-60 thousand kilometers, and during intensive driving "Ramp" replacement time is reduced to 30-40 thousand mileage. These recommendations are independent of the total mileage of the vehicle.
In some car models, the transmission oil is filled for life. In this case, the transaxle housing no drain plug.
Talking about the service of automatic transmissions can not fail to mention the CVT box has become so common in today's automotive industry. Although they are considered to be automatic, but are designed very differently and work very hard in the temperature regime. Average oil for automatic transmissions for them is not necessary - there is a special liquid. It is recommended to change the fluid in the variator every 40-50 thousand kilometers, while the replacement of intensive driving is reduced to 30 thousand. CVT fluid change intervals must be strictly observed since
how, because of the constant high load on the variator belt and hard temperature, additive package breaks down much faster than in the conventional transmission oil.
When replacing the gearbox oil gearbox housing is not washed - this is not necessary. When repairing a result of disassembling the box out manually removed and cleaned all the dirt magnet that collects the shavings are the result of the work gear. Not worth saving, and after assembling a box engineers dealerships recommend to fill in the new oil, even if the replacement was planned as recently as the use of fresh oil Security deposit reliable and durable work gearbox.
Modern synthetic gear oils are all seasons and can operate without losing its lubricating properties in a temperature range from -50 to +50 degrees Celsius. They did not thicken, do not lose their viscous properties of the cold and the heat, so cars with such oils can be used almost anywhere.
