FLUIDMATIC SYN NA is a high performance automatic transmission fluid designed to meet the requirements of most cars and SUV’s sold by US and foreign OEM’s. FLUIDMATIC SYN NA is recommended wherever Allison C-4 fluids are required. It may be used in multiple speed transmissions where either low or high viscosity ATF is specified. Due to its mid-grade viscosity, (positioned between high and low viscosity ATF ranges), it should NOT be sold in the state of California where viscosity ranges must match suitability claims. Always consult your owner’s manual for its suitability as ATF in imported vehicles.
