ZF TE-ML 12B

The ZF TE‑ML 12B specification defines the requirements for transmission lubricants for ZF automatic and manual gearboxes, particularly for heavy passenger and commercial vehicles equipped with 4HP, 5HP, 6HP and 8HP transmissions. Oil that complies with TE‑ML 12B must have a viscosity in the range 75 W‑90/140, provide high thermal resistance (up to 120 °C), resistance to load‑induced cracking, and effective protection of synchronizers, gears and bearings from wear. The specification calls for the use of base synthetic or synthetic‑mineral technologies that guarantee stable friction properties and minimal deposit formation in the system. Products approved under TE‑ML 12B are also compatible with the older ZF TE‑ML 02B, 02F and 03D requirements, allowing their safe use in upgraded transmissions without risking warranty loss. Choosing oil marked TE‑ML 12B on xenum.ua ensures long‑lasting gearbox operation, reduced noise, and improved fuel economy.
