Honda Ultra HMMF

The Honda Ultra HMMF specification is the official approval from Honda Motor Co. for transmission fluids intended exclusively for new‑generation automatic gearboxes, including 6‑speed ATs and certain CVTs installed in Honda and Acura models (Accord, Civic, CR‑V, Pilot, Odyssey, TLX, MDX, etc.), including hybrid variants. Technically, Fluid Ultra HMMF provides high thermal resistance, viscosity stability over a wide temperature range, and effective protection against oxidation and wear of friction elements, allowing optimal torque transfer and smooth shifting. The specification ensures compatibility with all friction disc, gear and clutch materials used in these transmissions, as well as with electronic control systems and temperature sensors. Although Ultra HMMF does not require special SAPS or DPF requirements, it is suitable for engines connected to post‑catalyst emission cleaning systems, as it contains no additives that could damage catalysts. On Xenum.ua you will find a transmission fluid that meets this standard, such as XA‑TRAN NIPPON ATF 1 L, which has passed full testing according to Honda Ultra HMMF requirements.
