Fluid Type Explained
The 2025 Mercedes-Benz Metris is equipped with the advanced 9G-TRONIC (725 series) automatic transmission. This sophisticated nine-speed automatic transmission requires a very specific fluid to ensure its longevity and optimal performance. The OEM (Original Equipment Manufacturer) fluid specification for this transmission is Mercedes-Benz ATF 236.15. This is a low-viscosity, high-performance fluid engineered to meet the precise demands of the 9G-TRONIC, including its friction characteristics, heat dissipation, and wear protection.
Using any fluid that does not explicitly meet the MB 236.15 specification can lead to significant transmission problems, such as premature wear of clutch packs, shuddering, shifting issues, and even complete transmission failure. Always double-check the fluid label to ensure it states compliance with MB 236.15. While some aftermarket fluids may claim compatibility, it is always safest to use genuine Mercedes-Benz fluid or an approved equivalent from a reputable brand.
Service Procedure
Servicing the 9G-TRONIC transmission typically involves either a "drain and fill" or a "full fluid exchange."
Drain & Fill
A drain and fill procedure involves removing the drain plug, allowing the old fluid to drain out, replacing the transmission filter, and then refilling with new fluid. This method replaces only a portion of the total transmission fluid, as a significant amount remains in the torque converter, valve body, and cooler lines. For the 2025 Metris 9G-TRONIC, a drain and fill typically replaces around 5.0 to 6.0 liters of fluid. While simpler, this method effectively dilutes the old fluid with new fluid. It
