vaihteistoöljy

Vaihteistoöljy, also known as transmission fluid, is a specialized lubricant used in the transmission system of vehicles. Its primary function is to reduce friction and wear between the moving parts within the transmission, ensuring smooth gear changes and efficient power transfer. Vaihteistoöljy also plays a crucial role in cooling the transmission, dissipating heat generated by friction. Furthermore, in automatic transmissions, it acts as a hydraulic fluid, transmitting power from the engine to the transmission and enabling the shifting of gears.

The type of vaihteistoöljy required depends on the specific transmission system. Automatic transmissions typically use automatic transmission fluid (ATF), which has specific properties for hydraulic operation and clutch engagement. Manual transmissions, on the other hand, generally use gear oil, which is thicker and designed to withstand higher pressures and shear forces. The viscosity and additive package of vaihteistoöljy are critical for optimal performance and longevity of the transmission. Regular maintenance, including checking and changing the vaihteistoöljy according to the manufacturer's recommendations, is essential to prevent damage and ensure the proper functioning of the transmission. Ignoring this maintenance can lead to increased wear, poor performance, and costly repairs.
