VOLVO 97940

VOLVO 97940 is a technical approval that sets the requirements for transmission oils for automatic gearboxes designed for passenger, commercial and hybrid Volvo models. The specification defines the viscosity range, oxidation stability, friction properties and wear protection, ensuring smooth shifting, proper operation of the lock‑up torque converter and durability of gears and seals. Oils that meet VOLVO 97940 are intended for gearboxes such as ZF 6HP/8HP, Volvo AW‑Series and similar, including electronically controlled systems, and do not contain components that could damage after‑treatment filters, as SAPS dependence is not relevant in this case. Although the specification is oriented toward new transmissions, it remains compatible with older models that previously required VOLVO 97940 approval, simplifying lubricant selection for service centers and car owners.
