Valvoline MaxLife Multi-Vehicle ATF is the full-synthetic automatic transmission fluid with MaxLife Technology that’s suitable for use in 95% of ATF vehicles in operation with US registered light duty applications. Formulated with advanced additives to prevent the major causes of transmission breakdown, it’s designed to help prevent leaks, reduce wear and tear, and maximize performance – all for much longer than conventional fluids. It has improved thermal stability for longer fluid life, better viscosity stability for consistent transmission operation, and specific frictional enhancements for smooth gear engagements. .
