vaihteistoöljyjä

Vaihteistoöljyjä, also known as transmission fluid, are specialized lubricants designed for use in vehicle transmissions. Their primary function is to reduce friction and wear between the moving parts within a gearbox, ensuring smooth and efficient operation. Different types of transmissions, such as manual, automatic, and continuously variable transmissions (CVTs), require specific types of vaihteistoöljyjä due to their distinct internal mechanisms and operating conditions.

Automatic transmission fluid (ATF) is particularly complex, as it not only lubricates but also transmits hydraulic power, cools the transmission, and provides friction for clutch engagement. Manual transmission fluid, on the other hand, is primarily focused on lubrication and protection against wear and corrosion. CVT fluid is formulated to handle the unique demands of belt or chain-driven systems.

The viscosity and additive package of vaihteistoöljyjä are critical. Viscosity determines the fluid's ability to flow and lubricate at different temperatures, while additives can include anti-wear agents, friction modifiers, detergents, and anti-foam agents. Using the correct type of vaihteistoöljyjä is essential for the longevity and performance of a transmission. Ignoring the manufacturer's recommendations can lead to premature wear, shifting problems, and costly repairs. Regular inspection and replacement of vaihteistoöljyjä according to the vehicle's maintenance schedule are vital for optimal transmission health.
