Castrol TranSynd 668 (TES295_TES468_TES668), 20L

Castrol TranSynd 668 is a fully synthetic automatic transmission oil specifically developed for Allison Transmissions®. It meets the requirements of the latest TES 668™ specification, offering excellent oxidation resistance, effective wear protection and an optimal coefficient of friction. The product provides longer driveline durability, reduces vibration and improves smooth shifting even under extreme operating conditions.

Use:

Recommended for industrial automatic transmissions, especially Allison®, in machines used in mining, heavy transport, construction and other applications requiring the highest resistance to loads and extreme temperatures.

Advantages and benefits:

• Improved gear protection: reduces mechanical wear and protects transmission components.
• Extended vibration resistance: increases the comfort and reliability of the system.
• Friction coefficient durability: ensures smooth gear changes in all conditions.
• High corrosion and foam resistance: guarantees stable operation of the system throughout its lifetime.
• Clean gear: allows for longer drain intervals and reduces service time.
• Reduced operating temperature: less friction = longer service life of oil and components.
• Winter smoothness: fast lubrication of components during cold start-ups.
• Optimized friction characteristics: smoother gear changes regardless of temperature and load.
• Shear resistance: consistent performance throughout the entire interval between replacements.

Classification according to standards:

• ISO VG: No classification (ATF product)
• Viscosity index: DIN ISO 2909 – 168
