Purpose and Specifications

LIQUI MOLY Top Tec ATF 1800 1L is a fully synthetic automatic transmission fluid built for modern 6+ speed transmissions in vehicles from GM, Ford, BMW, VW, Toyota, Honda, Nissan, Mazda, Land Rover, Fiat, Aisin Warner, and Mercedes. It delivers smooth shifting, cuts wear by protecting gears from friction, and keeps corrosion away for reliable performance in daily drives or heavy towing.

This premium oil shines with excellent viscosity that flows easily at cold starts down to -40°C for quick engagement, stays thick up to 200°C to handle heat from highways or hills, and resists aging for long fluid life. Foam prevention ensures consistent power transfer without slippage, while top oxidation resistance means fewer changes.

When to Use / Replace?

• Use in transmissions needing Dexron VI, Mercon ULV, ATF Type 3.1, JWS 3324, or VW G 055 specs for ultimate protection and shift quality.
• Replace every 60,000-100,000 km or 4-5 years under normal driving; check sooner at 30,000 km for towing, city stop-go, or hot climates over 35°C average.
• Shelf life is 5 years unopened; store cool and dry.
