Greyhound Transmission TO-4 SAE 30 20L
Greyhound Transmission TO-4 SAE 30 is a specialist powertrain lubricant engineered for Caterpillar and yellow-equipment transmissions and hydraulic systems. Specifically, this 20L SAE 30 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 30 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.
Transmission And Hydraulic Protection
For example, SAE 10W and 30 grades are optimised for transmission and hydraulic duty, while SAE 50 and 60 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.
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
- Increased film strength protects gears, bearings and clutches
- Optimised for transmission and hydraulic systems
