Castrol TRANSMAX Universal LL 75W-90 is a fully synthetic multi-purpose manual transmission and final drive lubricant. Formulated with Smooth Drive Technology, it features active control molecules that adjust friction levels under changing pressures and speeds, ensuring a smoother drive for longer and enhanced protection. This fluid is suitable for synchronised manual transmissions and final drives/differentials in a wide range of vehicles, including commercial vehicles and construction equipment, where API GL-4 or API GL-5 fluids are required. It meets various industry standards and approvals, including API GL-4/GL-5/MT-1, SAE J2360, MAN 341 Z2, MAN 342 S1, MB-Approval 235.8, Scania STO 1:1G, Scania STO 2:0A FS, Volvo Transmission Oil 97312-047, and ZF TE-ML 02B, 05A, 12L, 12N, 16F, 17B, 19C, 21A. It is also approved for Eaton Europe for drain intervals up to 300,000 km for synchronised manual transmissions. The excellent low-temperature fluidity improves shift quality and wear protection in cold conditions, while also enhancing fuel efficiency. This single product for transmissions and final drives helps reduce inventory and the potential for misapplication.
