FORD WSS-M2C118-A

The FORD WSS‑M2C118‑A specification is Ford’s official standard for synthetic and mineral transmission oils, primarily intended for manual gearboxes of Ford passenger and commercial vehicles, including models with 5‑, 6‑ and 7‑speed mechanisms (e.g., 5R55, 6R140, 6R120). Viscosity requirements (e.g., 75W‑140) ensure stable operation over a wide temperature range, and special anti‑wear and oxidation additives guarantee long‑lasting protection of synchronizers and gears under high load. The specification provides compatibility with after‑treatment filter systems (DPF) and catalysts, as the oil does not contain high levels of SAPS, allowing safe operation of low‑emission technologies. Products that meet WSS‑M2C118‑A are suitable for both new models and older versions that previously required similar standards, such as Ford M2C922‑A1. Using lubricant approved to this standard ensures compliance with warranty conditions and minimizes the risk of premature transmission wear.
