ASTON MARTIN ATF AML 4G4319A509S

The ASTON MARTIN ATF AML 4G4319A509S specification defines the requirements for ATF AML type transmission oil developed for automatic and dual‑clutch premium Aston Martin models. The oil must have a synthetic base with high thermal resistance (operates up to +150 °C), stability under high torque, low viscosity on cold start, and controlled friction behavior, providing smooth and rapid shifts without slip. The specification covers V8 and V12 engines installed in the DB11, Vantage, DBX and other sports and off‑road models where the transmission is subjected to intensive loads. It guarantees protection of gears, friction discs and hydraulic systems from oxidation, corrosion and deposit formation, as well as compatibility with electronic torque‑control systems. By choosing an oil that meets ATF AML 4G4319A509S, such as XENUM XA‑TRAN 6G, you preserve the transmission’s factory characteristics and extend the gearbox service life without risking warranty loss.
