What gearbox oil to use in Renault megane automatic?

For a Renault Megane with an automatic transmission, it is recommended to use Renault's own ATF (Automatic Transmission Fluid) specifically designed for their vehicles, such as the Elf Tranself NFX or equivalent. Always check the owner's manual for the exact specifications and fluid type required for your specific model and year, as variations may exist. Using the correct fluid is crucial for optimal transmission performance and longevity.
