Castrol Syntrans 75W-85 is a full synthetic transmission fluid recommended for most commercial vehicle manual transmissions (truck, bus, light commercial vehicle) where API GL-4 lubricants are required. These transmissions are generally larger and subjected to higher loads and temperatures than those in passenger cars; this product was developed for these particular requirements and is approved by a number of manufacturers.
Features and Benefits
- Excellent thermal and oxidative stability maintains transmission cleanliness and lubricant performance, allowing extended drain capability.
- Synthetic formulation provides a reduction in operating temperatures, giving longer component and lubricant life.
- Superb cold flow characteristics give smoother gear shifts at low temperatures.
- High shear stability maintains lubricant performance throughout the drain interval.
- Good wear and EP performance ensures component protection under high load conditions, reducing downtime and service costs.
