Transmission TO-4 SAE 10W

Transmission Oil TO-4 SAE 10W – for Yellow Equipment Drivetrains

Greyhound Lubricants Transmission Oil TO-4 SAE 10W is a premium drive-train lubricant formulated for use in Caterpillar and other heavy equipment requiring the TO-4 specification. It is designed for power shift transmissions, direct drives, differentials, final drives, wet brakes, and hydraulic systems used in construction, mining, and earthmoving machinery.

The TO-4 range (SAE 10W, 30, 50, and 60) provides superior friction control, improved clutch durability, and reliable wear protection. SAE 10W and 30 grades are recommended for transmission and hydraulic systems, while SAE 50 and 60 are designed for differentials and final drives where extreme load conditions apply. Formulated with high-quality base oils and an advanced additive system, this lubricant ensures long component life and stable performance across severe operating temperatures.

Specifications: ISO VG10; CAT TO-4; GL-3/4; Allison C-3/C-4; KOMATSU KES 07.868.1; DANA; Vickers M-2950-S; EATON-Fuller; EUCLID; TREMEC/TTC.

• Improved clutch life: Up to 45% longer service versus TO-2 fluids; balanced friction properties ensure smooth power transfer and maximum productivity.
• Outstanding wear protection: Excellent shear stability, viscosity retention, and film strength minimise wear on gears, bearings, and clutches.
• High-temperature stability: Resists oxidation, sludge, and deposit formation for longer oil life under severe service.
• Low-temperature performance: Excellent cold-flow characteristics ensure quick lubrication and easy gear shifting in cold starts.
