How Often Should the Transmission Fluid of Nissan Sylphy Be Changed?

[MacLaila]

Under normal circumstances, it is recommended to change it once within four years or 80,000 kilometers. This is because, under normal conditions, impurities from the air entering the transmission can contaminate the fluid, and component wear can also increase internal impurities. Additionally, exposure to oxygen can degrade the fluid's oxidation resistance. Over prolonged use, the fluid's anti-foaming and cleaning dispersion properties also diminish. Therefore, according to the design requirements of the fluid manufacturer, the transmission fluid should be replaced at regular intervals. Cooling function of transmission fluid: The interaction between gears generates a significant amount of heat, which needs to be dissipated by the lubricating fluid. Lubrication function of transmission fluid: It ensures smoother gear engagement. Cleaning function of transmission fluid: It maintains the cleanliness of the shifting system and extends the lifespan of the transmission components.
