ISUZU Besco ATF SP

The ISUZU Besco ATF SP specification defines the requirements for transmission oil used in automatic gearboxes of the Besco series from Isuzu. The oil must have a stable viscosity in the range of 6,5–7,5 cSt at 100 °C, high resistance to oxidation and thermal degradation, and also provide an optimal friction coefficient for smooth gear shifts and reliable hydraulic torque converter lock‑up. This standard applies to passenger, commercial and heavy‑duty Isuzu vehicles, including N‑Series, F‑Series, D‑Series models and buses equipped with Besco automatic transmissions. Oils that meet ISUZU Besco ATF SP do not contain components that harm catalysts or DPF, therefore they can be safely used in modern emission systems. The XENUM catalog features two products that have passed this approval: XA‑TRAN NIPPON ATF (1310001A) and XA‑TRAN DX VI, guaranteeing compliance with the manufacturer’s requirements and preservation of warranty conditions.
