Information about Castrol TranSynd 668 Allison TES Full Synthetic Automatic Transmission

What is TransSynd 668?

Castrol TranSynd 668 is a premium, full-synthetic automatic transmission fluid specifically formulated for Allison Transmission® on-highway automatic transmissions. TranSynd 668 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 with both Allison TES 295® and TES 468™ applications.

Castrol TranSynd 668 enhances the groundbreaking design and performance of the original TranSynd formula for Allison TES 295 and TES 468 Transmissions.
Providing exceptional improvements in wear/gear protection, extended drain intervals up to 12 times longer in general-duty and severe-duty transmissions, extended clutch-friction durability, lower deposit formation, corrosion and foaming resistance, and more.

TranSynd 668 is one of the best transmission fluids available on the market currently. Developed specifically to meet rigorous Allison specifications for heavy-duty working trucks. Also works in GM transmissions like 4L80 and 6L90 and has better performance than standard ACDelco or GM Dexron VI or III fluids.
