Catalys Trans TO-4 SAE 30



TRANS TO-4 oils are high-quality lubricants intended for transmissions, final drives and hydraulic systems that require a fluid compliant with the Caterpillar TO-4, Komatsu KES 07.868.1, and Allison C4 standards.


These oils are made from highly refined base oils to which detergents, dispersants, antioxidants, and other inhibitors have been added to increase performance. TRANS TO-4 oils increase the equipment’s service life by reducing damages from friction and wear. They can also be used when Caterpillar TO-2 oil is specified.
As an example, TRANS TO-4 oils can be used in Komatsu assisted transmissions, in Terex construction equipment and any other application requiring fluids that meets the Caterpillar TO-4 specification.
