Váltóolaj

Váltóolaj, 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 moving parts within the gearbox, ensuring smooth gear changes and efficient power transfer. Váltóolaj also plays a crucial role in cooling the transmission, preventing overheating caused by the constant motion of components.

The composition of váltóolaj varies depending on the type of transmission it is designed for, such as manual or automatic. Manual transmission fluid typically contains additives that enhance lubrication under high pressure and shear forces. Automatic transmission fluid (ATF) is more complex, often including detergents to keep the system clean, anti-foaming agents, and viscosity modifiers to maintain consistent performance across a range of temperatures.

Regular inspection and replacement of váltóolaj are essential for maintaining the longevity and performance of a vehicle's transmission. Over time, the fluid can degrade, lose its lubricating properties, and accumulate contaminants. This can lead to increased wear, slipping gears, and ultimately, costly transmission repairs. The recommended service intervals for váltóolaj changes are usually specified in the vehicle's owner's manual. Using the correct type and specification of fluid is critical, as using the wrong type can cause significant damage to the transmission.
