Transmission Fluid; Transynd 668;

Castrol TranSynd 668 has been specifically formulated for Allison Transmission on-highway automatic transmissions. This premium, full-synthetic fluid is Allison TES 668-approved and it builds on the demonstrated performance of the previous Allison TES 295 spec with key differentiators that include improved wear protection, extended anti-shudder durability, and extended clutch-friction durability. TranSynd 668 is fully backwards compatible for both TES 295 and TES 468 applications.*

* TES 668 is not approved for TC10.
