Chevron MD-3 Automatic Transmission Fluid is a passenger car and light truck automatic transmission fluid for most pre-2006 automatic transmissions built by General Motors, Ford Motor company and other makes requiring a high-performance, multi-purpose, power transmission fluid. It is formulated with premium, severely hydro processed base stocks and additives that helps provide oxidation and thermal stability, friction control, load-carrying ability, corrosion and wear protection. It helps protect against the formation of deposits, sludge, varnish, and foam. Chevron MD-3 automatic transmission fluid helps provide outstanding durability. Under severe operating conditions, this fluid maintains friction control for smooth shift action, is specially formulated to help prevent shudder, retains low temperature fluidity and high temperature stability for long operating periods, protects automatic transmission fluid coolers from corrosion, and helps minimize the chances of a transmission overhaul due to sludge, corrosion, and wear. It is recommended for applications that call for the former DEXRON-III H, MERCON, and Allison C-4 fluids.
