ASTON MARTIN ATF AML 4G4319A509AA

The ASTON MARTIN ATF AML 4G4319A509AA specification defines the requirements for transmission fluid for automatic gearboxes, developed specifically for high‑performance Aston Martin models. It calls for the use of a synthetic base with high thermal resistance, viscosity stability and the ability to maintain optimal torque levels at temperatures up to 150 °C and loads typical of sports and luxury cars. Fluid that meets this approval is suitable for automatic and dual‑clutch transmissions in models such as DB11, Vantage, DBX and other newer series where electronically controlled gearboxes with torque‑management systems are employed. The technical description includes requirements for low gear‑wheel wear, oxidation protection and filter cleanliness retention, ensuring long‑lasting reliable operation without adverse impact on the catalyst or DPF. In the XENUM catalog this specification is represented by the synthetic transmission fluid XA‑TRAN 6G, which fully complies with ATF AML 4G4319A509AA and guarantees preservation of the factory transmission characteristics during service.
