Chevron unveils Delo Syn ATF 668, a fully synthetic ATF

Chevron Products Company, a division of Chevron U.S.A. Inc., unveiled Delo Syn ATF 668, a fully synthetic automatic transmission fluid (ATF) specifically engineered for Allison’s heavy duty automatic truck and bus transmissions.

Allison Transmission is the world’s largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles and is a leader in hybrid-propulsion systems for city buses.

Engineered for longer service life, improved transmission performance, optimal fluid performance and improved clutch operation, Delo Syn ATF 668 is approved and licensed by Allison for transmissions requiring TES 668. The transmission fluid is backward 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, building and improving 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,” said 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.”

Allison has recommended that all current users of TES 295 or 389 fluids begin the transition to an approved TES 668 fluid. 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, according to Chevron.
