High-Capacity Fluid Delivery System - This 7.5L (2-gallon) fluid pump delivers 76.5g of fluid per stroke, making it ideal for fast and efficient automatic transmission fluid (ATF) changes. The transparent tank features volume scales for precise fluid level monitoring during filling. Universal Compatibility - Includes 15 professional-grade ATF adapters compatible with BMW, Audi, Volkswagen, Mercedes-Benz, Porsche, Ford, and most automatic/manual transmissions. Genuine parts ensure leak-proof connection to the master cylinder. Precise and Error-Free Design - Equipped with a flow control valve that stops dispensing as soon as the desired fluid level is reached to prevent spills. The weighted base and non-slip handle ensure operational stability even in cramped engine compartments. Industrial Strength Construction - Made with chemical-resistant nylon hoses, aluminum alloy fittings, and a rugged HDPE reservoir, it's heat and corrosion resistant. It's far more durable than plastic pumps.
