Castrol TranSynd 668 Fluid

Castrol TranSynd is a premium, full-synthetic automatic transmission fluid specifically formulated for Allison

Transmission® on-highway automatic transmissions. TranSynd provides oxidative stability, anti-wear performance,

and friction durability, as well as TES 668™ specification differentiators such as extended anti-shudder durability and

extended clutch friction durability. This fluid features an Allison TES 668 approval.

The TES 668 spec is fully backwards

compatible for TES 295® applications, but is not backwards compatible for TES 468™ applications (Hybrid Buses).



·         Delivers improved gear protection.

·         Delivers extended anti-shudder durability.

·         Delivers extended clutch-friction durability.

·         Excellent corrosion and foaming resistance.

·         Excellent thermal and oxidative stability that helps to prevent deposits and oil thickening.

·         Excellent transmission cleanliness under all conditions permits extended oil-drain intervals and decreased servicing.

·         Excellent temperature reduction through reduced friction leads to longer oil and component life.

·         Outstanding cold-flow properties enables faster oil flow to all critical components particularly during cold starts.

·         Optimized frictional characteristics gives smoother gear changing at all ambient temperatures and load conditions.

·         Excellent shear stability properties help to retain full transmission performance over entire oil-drain interval.
