Greyhound Transmission TO-4 SAE 10W 20L
Greyhound Transmission TO-4 SAE 10W is a specialist powertrain lubricant engineered for Caterpillar and yellow-equipment transmissions and hydraulic systems. Specifically, this 20L grade protects power-shift and direct-drive transmissions, final drives, differentials, winches, clutch plates, gears and bearings.
Because heavy earthmoving machines demand precise frictional control, this Transmission TO-4 SAE 10W oil delivers balanced static and dynamic friction. Moreover, it meets Caterpillar’s latest drive-train requirements, so operators gain durable clutch performance and maximum power transfer throughout the service interval.
Built For Yellow Equipment Drivetrains
For example, the SAE 10W grade is optimised for transmission and hydraulic duty, while SAE 30, 50 and 60 grades cover heavily loaded gears and final drives. In addition, superior shear stability protects clutches and bearings. As a result, equipment productivity rises and downtime falls. Therefore, fleets running construction plant gain longer transmission life and lower operating costs.
Key Features:
- Improved clutch life: up to 45% over TO-2 fluids
- Balanced static/dynamic friction for clutch durability and power transfer
- Outstanding shear stability and viscosity retention reduce wear
- Excellent thermal, oxidation, sludge and corrosion protection
- Superior low-temperature fluidity for reliable cold shifting
- Increased film strength protects gears, bearings and clutches
