LIQUI MOLY ATF Additive 20040 is a German-engineered additive for automatic transmissions. This 250 ml tube blends with existing ATF to optimize friction behavior, promote smoother shifts, and help protect gears and seals from wear and heat. LIQUI MOLY, a well-established German lubrication brand, is known for engineering-driven, reliable automotive products, and this ATF additive continues that tradition with a focus on longevity and performance.

Use it when transmission performance declines due to aging fluid or deposits. Common symptoms include harsh or delayed shifts, slipping, or higher transmission temperatures. The additive supports oxidation resistance and friction stability, helping extend ATF life and maintain consistent performance in select European applications. Part number 20040.
