Advanced Synthetic Technology Automatic Transmission Fluid

Product Description

Mobil Delvac 1 ATF 668 is an advanced synthetic technology fluid recommended by Allison Transmission, Inc. approved against the Allison TES-668 Specification. The fluid is designed to meet the demanding requirements of modern heavy duty automatic transmissions. The synthetic technology base oil composition enables excellent performance even in some of the harshest of operating conditions. It offers outstanding gear shifting and power transfer performance. Versus conventional ATF fluids, the inherently high viscosity index and stability of Mobil Delvac 1 ATF 668 protects against thermal breakdown at high operating temperatures, while still providing outstanding performance at sub-zero temperatures.
