CITGO TRANSGARD Heavy-Duty Transmission Fluids are new generation Allison C-4 and CAT TO-4 transmission and drivetrain fluids. They are designed for heavy-duty construction equipment powershift transmissions, final drives and wet brakes. Compared to engine oil, TRANSGARD HeavyDuty Transmission Fluids will improve transmission performance and power transfer under conditions of high horsepower output, increased loads, and higher transmission operating temperatures associated with heavy equipment. Base stocks and additives are carefully selected for compatibility with clutch face and seal materials. Available Viscosity Grades: 10W, 30, 50 and 60. These fluids are recommended for lubrication of winch, clutch plates, gears and bearings. They will help reduce brake chatter in wet brake applications.
