ZF 8HP55

The ZF 8HP55 specification defines the requirements for transmission oil intended for 8‑speed automatic gearboxes of the 8HP55 series, which are installed in new passenger car models with gasoline and diesel engines (for example, BMW 5‑Series, Audi A6, Volkswagen Passat, Mercedes‑C‑Class). Oil that meets this approval must be synthetic, have high thermal resistance (operates up to 150 °C), provide stable viscosity, wear and oxidation protection, and also a low coefficient of friction for smooth operation of the hydraulic system. The specification provides compatibility with diesel particulate filter (DPF) after‑treatment systems and catalysts, therefore it does not contain high levels of SAPS, which allows avoiding filter contamination. Using oil approved to ZF 8HP55 guarantees proper operation of valve and friction elements, prevents overheating and extends transmission life. When selecting a product on xenum.ua, for example XA‑TRAN 8G, you receive full compliance with these technical requirements.
