Transmission Fluids Product Data castrol.com/GPS 800 255 4417 May 2025 GPS Castrol ® Transynd ® 668 Castrol TranSynd 668 is a premium, full-synthetic automatic transmission fluid specifically formulated for Allison Transmission ® on-highway automatic transmissions. TranSynd 668 provides oxidative stability, anti-wear performance, and friction durability, as well as TES 668 TM specification differentiators such as extended anti-shudder durability and extended clutch friction durability. is fluid features an Allison TES 668 approval. e TES 668 TM spec is fully backwards compatible for both TES 295 ® and TES 468 TM applications, but is not approved for TC10. Features and Benefits Castrol TranSynd 668 delivers: • Improved gear protection • Extended anti-shudder and clutch-friction durability • Excellent corrosion and foaming resistance • Excellent thermal and oxidative stability that helps to prevent deposits and oil thickening • Excellent transmission cleanliness for extended oil-drain intervals and decreased servicing • Excellent temperature reduction through reduced friction, leading to longer oil and component life • Outstanding cold-flow properties/faster oil flow to critical components particularly during cold starts • Optimized frictional characteristics for smoother gear changing at ambient temperatures/load conditions • Excellent shear stability properties help retain full transmission performance for entire oil-drain interval Castrol TranSynd 668 can deliver up to 12 times longer drain intervals than conventional and other non- Allison-approved synthetic fluids. is can reduce costs in inventory, labor, used-oil disposal, and equipment downtime. Industry Specifications and OEM Approvals: • Allison TES 668 TM (fully backwards compatible with Allison TES 295 ® and TES 468 TM but not approved for TC10).* • DTFR 13C190 (MB 236.92) • MAN 339 V1 • Voith H55.6335.xx • Volvo Transmission Oil 97341 *TES 668 TM builds on the demonstrated performance of the previous TES 295 ® spec in key areas such as oxidative stability, anti-wear performance, and friction durability. e spec differentiators include improved wear protection, extended anti-shudder durability, and extended clutch-friction durability.
