SUNOCO DURATRANS ATF 668 has been approved by Allison Transmission against their Nex-Gen global automatic transmission specification, TES 668™.   This heavy-duty ATF is designed for all current and future Allison transmissions and is fully backwards compatible for all Allison transmissions that require an approved TES 295™ fluid.  Specifically designed to replace and build upon the performance and durability of TES 295™, SUNOCO DURATRANS ATF 668 has been thoroughly tested by Allison Transmission for optimal performance and durability.


SUNOCO DURATRANS ATF 668 provides unparalleled protection for heavy-duty automatic transmissions in severe and extended drain service.  Like all SUNOCO DURATRANS products, DURATRANS ATF 668 is full synthetic to provide longer service life.  Its increased oxidative stability helps to lower total operational costs while improving on-road performance.  Improved transmission performance and feel are products of the exceptional friction modifiers that are employed to not only provide smoother shifts, better anti-shudder and clutch responses, but also to increase wear protection to extend the life of valuable components.  Combined with back-serviceability to all previous TES 295™ applications, SUNOCO DURATRANS ATF 668 is the only choice for the utmost in Allison warranty and transmission protection.


SUNOCO DURATRANS ATF 668 is approved for use in any automatic transmission that specifies an Allison approved TES 668®, TES 295®, or TES 468® fluid, including H 40 EP™, H50 EP™ Hybrids and eGen Flex™ models.
