Chevron Introduces Delo® Syn ATF 668, a Fully Synthetic Transmission Fluid Approved and Licensed by Allison Transmission® for Transmissions Requiring TES 668™

DESIGNED FOR SEVERE DUTY, LONGER SERVICE LIFE AND EXTENDED DRAIN INTERVALS, DELO SYN ATF 668 DELIVERS OPTIMAL PERFORMANCE FOR ALL ALLISON TRANSMISSIONS REQUIRING TES 668 FLUID

Chevron Products Company launched Delo Syn ATF 668, a fully synthetic transmission fluid engineered for Allison heavy-duty automatic truck transmissions.

Chevron engineered Delo Syn ATF 668 for longer service life, improved transmission performance, optimal fluid performance, and improved clutch operation. Allison approved and licensed Delo Syn ATF 668 for transmissions requiring TES 668; it is also backwards compatible with TES 389® and TES 295®. Manufactured with synthetic base oils and state-of-the-art additives, it is a next-generation fluid for modern Allison transmissions. Additionally, this builds and improves on the proven performance of TES 389 and TES 295 fluids.

“We developed Chevron Delo Syn ATF 668 to meet the needs of businesses and municipalities who operate fleets that traditionally rely on vehicles with Allison transmissions,” says Jason Gerig, Chevron Americas Commercial On & Off Highway Sector Manager. “With Delo Syn ATF 668, we are enabling work truck and bus operators to decrease maintenance needs and increase the amount of time a vehicle can remain in operation for critical services to communities.”

EXTENDED ANTI-SHUDDER DURABILITY FOR SMOOTH & STEADY OPERATION

Delo Syn ATF 668 offers improved transmission performance. This is possible because it provides more than 13 times anti-shudder durability compared to TES 295 fluids. This allows for smoother shifts at low speeds and over a wider temperature range.

EXTENDED CLUTCH FRICTION DURABILITY FOR CONSISTENT GEAR CHANGE

Delo Syn ATF 668 features exceptional clutch operation across temperature variations as well as load sizes as the fluid ages in the transmission under extreme working conditions. Optimal fluid performance enables fast circulation and efficient power transfer in the most demanding conditions and during cold weather start-ups.

SUPERB OXIDATION PERFORMANCE FOR EXTENDED DRAINS

Delo Syn ATF 668 offers longer service life and lower maintenance costs. This is because it features  improved anti-wear protection, antioxidation, and shear stability over TES 295 fluids. These advantages reduce noise as well as vibration, harshness, and maintain hardware reliability for extended drain intervals.

Additionally, Allison recommends that all current users of TES 295 or 389 fluids begin the transition to an approved TES 668 fluid, and Delo Syn ATF 668 can be mixed with these fluids without the need to change drain intervals, allowing fleets to remain in full operation as they transition to 668 fluids.

APPLICATIONS

  • Allison transmissions that specify TES 668 fluids
  • All 1000, 2000, 3000, and 4000 series transmissions where TES 295 is specified for extended drain intervals
  • All 1000, 2000, 3000, and 4000 series transmissions where TES 389 is specified for standard oil drain intervals
