ARVIN MARITOR O-76N

Specification ARVIN MERITOR O‑76N is a requirement for automatic transmission fluids developed by ArvinMeritor for heavy commercial vehicles. It calls for a synthetic base with high viscosity stability, a controlled friction coefficient, wear and oxidation protection, and the ability to operate over a wide temperature range—from –40 °C to +120 °C. The primary recipient engines are Allison automatic gearboxes (series C‑3, C‑4, TES‑228, TES‑295, TES‑389) and other heavy‑truck and bus transmissions that require high resistance to overheating and precise torque transfer. Oil that meets O‑76N is compatible with post‑catalytic cleaning systems because it contains no sulfate additives that could damage DPFs or catalysts. In the XENUM catalog this specification is represented by the transmission fluid X‑TRAN 75W90 GL5, which provides long‑lasting protection and smooth transmission operation even under extreme service conditions.
