The leading-edge lubricant technology in DuraDrive HD Synthetic 668 is specially formulated for Allison Transmission’s TES 668™ specification.


Providing anti-shudder durability 13 times greater than the reference fluid, two times better oxidation control, and optimal wear protection1, DuraDrive HD Synthetic 668 sets a new standard for ATF durability, transmission performance and equipment protection.

"We are proud to have worked with Allison Transmission to develop an automatic transmission fluid that exceeded the demanding standards set by their TES 668™ specification."
