FORD WSS-M2C938-A

The FORD WSS‑M2C938‑A specification defines the technical requirements for automatic transmission fluids used in passenger cars and light commercial vehicles from Ford with multi‑speed gearboxes (6‑, 7‑ and 8‑speed) and some CVT systems. The requirements include viscosity stability over a wide temperature range, high oxidation resistance, wear protection, and precise friction‑coefficient control, which ensure smooth gear shifts and proper operation of electronic transmission control. The specification provides compatibility with catalysts and diesel particulate filter (DPF) systems, so fluids that meet WSS‑M2C938‑A are safely used in gasoline and diesel engines equipped with these systems. For workshop technicians this guarantees compliance with Ford warranty conditions and minimizes the risk of premature transmission wear, and on xenum.ua you can quickly find products certified to this standard, including the XA‑TRAN CVT and XA‑TRAN DX VI transmission fluids.
