Castrol Transmax Z Automatic Transmission Fluid 4L is a full synthetic fluid specifically engineered to meet the demanding needs of buses, coaches, and commercial vehicles operating under heavy loads or extreme conditions. This high-performance transmission fluid is ideal for applications where General Motors type fluids are recommended and is also proven in high-performance environments like drag racing, including the Lenco drag racing transmission in Pro Stock.

The fluid features excellent resistance to oxidation, significantly prolonging the life of both the lubricant and the transmission. Its extended oil drain potential helps reduce operating costs by increasing intervals between oil changes, while optimised frictional characteristics ensure smoother gear shifts and better protection against wear.

Castrol Transmax Z also offers outstanding cold flow properties, helping to reduce wear during start-up, and temperature reduction in severe service conditions, which helps in improving both transmission and oil service life while assisting in reducing fuel consumption and emissions. The fluid also maintains low foam and stable gear-shifting performance even under hot transmission conditions.

Features:

• Oxidation Resistance: Extends lubricant life and maintains transmission performance.
• Extended Oil Drain Potential: Reduces operating costs by prolonging fluid life.
• Enhanced Deposit Protection: Keeps the transmission clean and extends its lifespan.
• Temperature Reduction: Improves service life of transmission and oil, reducing fuel consumption and emissions.
• Optimised Friction Characteristics: Provides smoother gear changes and better wear protection.
• Outstanding Cold Flow: Minimises wear at start-up, improving engine protection.
• Low Foam Stability: Maintains stable gear shifts even under hot conditions.
• Compatibility: Can be mixed with mineral/conventional automatic transmission fluids.

Applications:

• Buses, coaches, and commercial vehicles operating under heavy loads or extreme conditions.
• Recommended for use where General Motors type fluids are required.
• Suitable for use in a wide range of Asian, European, and American vehicles, including Toyota, Nissan, Mitsubishi, Mazda, Subaru, Hyundai, Kia, Honda, and many more.
