Mobil Delvac 1 ATF is a fully synthetic fluid recommended
by Allison Transmission, Inc. approved against the Allison
TES-295 Specification. The fluid is designed to meet the
demanding requirements of modern heavy duty automatic
transmissions. The synthetic 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 protects against thermal breakdown at
high operating temperatures, while still providing
outstanding performance at sub-zero temperatures.
