PSA ATF 9734 S2

Specification PSA ATF 9734 S2 is a PSA (Peugeot Société Anonyme) requirement for transmission fluids intended for automatic gearboxes installed in Peugeot, Citroën, DS, Opel/Vauxhall and other Stellantis vehicles. A fluid that meets PSA ATF 9734 S2 must provide stable viscosity over a wide temperature range, high resistance to oxidation and deposit formation, and also satisfy friction characteristic requirements needed for electronic clutch control and hydraulic valves. The specification provides compatibility with many modern PSA automatic transmissions, including 6‑speed and 8‑speed gearboxes (EAT6, EAT8) and their dual‑clutch variants. The XENUM XT‑POWERSHIFT transmission oil, marked PSA ATF 9734 S2, meets these requirements and delivers long‑lasting wear protection, preservation of torque transfer efficiency and prevention of overheating. Using a fluid approved to PSA ATF 9734 S2 guarantees compliance with OEM requirements without the need for additional modifications.
