TRIAX Fleet HD ATF Full Synthetic TES 295, TES 668

TRIAX Fleet HD ATF is a premium full synthetic automatic transmission fluid for heavy-duty applications in trucking, mining, agriculture, and more. Designed for smooth shifting and optimal performance in heavy transmissions, it offers high oxidation stability and viscosity control across a wide temperature range, including arctic conditions. It extends drain intervals up to six times longer than conventional ATFs, with improved shear stability, oxidation resistance, and wear protection.

• MEETS TES 295 / TES 389 / TES 668 SPECS: Specifically engineered for heavy-duty truck transmissions requiring Allison TES 295, TES 389, and TES 668 performance in both medium and severe service applications.
• WIDE OEM & EUROPEAN COMPATIBILITY: Compatible with MAN 338 Type V2 & Z11, MAN 339 Type L1 & Z2, Mercedes-Benz 236.9 / 236.91, Volvo 97341 / 9734, and ZF TE-ML 03D, 04D, 14B, 17C, 20B, 25B, and more.
• FRICTION-OPTIMIZED SHIFT PERFORMANCE: Delivers long-term shift stability, high torque transfer, and smooth, precise shifting with no slipping, sticking, or gear kick; excellent oxidation resistance prevents varnish, sludge, and deposits.
• EXTENDED DRAIN INTERVALS & COST SAVINGS: Up to 6× longer drain intervals than conventional ATF; rated for 100,000+ highway miles and 50,000+ miles in severe off-road service, reducing downtime and maintenance costs.
• HEAVY-DUTY PROTECTION & SEAL CARE: High film strength and load capacity protect clutches, bands, gears, and bearings; advanced seal conditioners prevent shrinkage, cracking, and leaks while ensuring reliable cold starts down to -50°F.
• Extended Transmission Servicing: Less sludge, corrosion, leaks, loss of frictional properties & wear of clutches, bands, gears & bearings; -50 F pour point for quick lubrication on startup in the cold
