Autran 4 30 is a transmission fluid specifically developed for use in powershift, direct drive transmissions, wet-disc brakes, differentials and final drives of Caterpillar equipment where Caterpillar TO-4 performance level is required.
Improved friction and anti-wear performance compared to CD/TO-2 fluids.
Stable friction characteristics, eliminating transmission slippage and reducing excessive brake noise making transmissions easier to operate.
Enhanced wear protection to final drive gears leading to longer unit life.
Excellent oxidation stability, and protection against corrosion and rust.
