Long Live Your Allison Transmission

Why are Allison Approved synthetic transmission fluids the best option for Allison Automatics? Because the specification was developed by people who know Allison best. Allison Approved synthetic fluids provide extended drain intervals and offer thermal and viscosity advantages over conventional petroleum based fluids, as well as other synthetic fluids. Allison Approved Fluids that are synthetic based offer improved viscosity that other fluids can’t offer.


Only Allison Approved transmission fluids are formulated for the unique components of an Allison Automatic. Allison has developed a Fluid + Filter Calculator available on the Allison HUB™, which provides change interval information.
