Greyhound Transmission TO-4 SAE 40 5L
Greyhound Transmission TO-4 SAE 40 is a special lubricant for Caterpillar and yellow-equipment transmissions and hydraulic systems. Specifically, it lubricates power shifts, direct-drive transmissions, final drives, differentials, winches, clutch plates, gears and bearings.
Because it meets Caterpillar’s latest drive-train specifications, it balances static and dynamic friction for clutch durability. Moreover, it improves clutch life by up to 45% over TO-2 fluids, so equipment stays productive.
Heavy-Equipment Drive-Train Protection
For example, outstanding shear stability and film strength reduce wear on gears and bearings. In addition, strong thermal and oxidation control eases transmission temperatures. As a result, transmissions last longer. Therefore, this oil competes directly with the oil majors.
