MOBIL DELVAC 1 ATF 668 is a fully synthetic, heavy-duty automatic transmission fluid specifically engineered to meet Allison Transmission's rigorous TES 668 specification. Designed for commercial vehicles operating in severe service environments, such as transit buses, refuse haulers, and utility trucks, it delivers exceptional shear stability, oxidation resistance, and friction durability. The advanced formulation ensures consistent anti-shudder performance, superior low-temperature fluidity, and maximum protection against wear, varnish, and deposit formation. This helps extend transmission durability and enables extended drain intervals, ensuring reliable, long-term fleet performance.
