Mityvac MV6412A ATF Refill System combines our hand operated pressure dispenser with our popular ATF refill adapter kit to provide a complete system for servicing today's sealed automatic transmissions. The dispenser allows the operator to fill or top-off transmissions with up to 2.5 Gal. of fluid between refills while the pressurized operation frees the operator from continual pumping. The refill system features a flow control valve conveniently located near fluid outlet as well as an integrated safety/manual pressure relief valve. The system utilizes push-to-connect, quick-change style accessory connections. A gauge indicates fluid reservoir pressure. The kit includes a custom-molded storage case for all adapters. Mityvac low-volume, low-pressure fluid dispensers offer a clean and convenient means of filling or topping-off automatic transmissions, radiators/coolant reservoirs, differentials and power steering and brake system pressure bleeding.
