Purpose and Specifications

LIQUI MOLY ATF Additive 250ml (5135) is a premium treatment for automatic transmissions and power steering systems using ATF II and ATF III oils. This 0.25-liter tube keeps rubber and plastic seals soft and flexible, preventing leaks from hardened seals that cause oil loss and costly repairs. It cleans internal oil passages for smooth flow, reduces gear noise, and improves shifting for a quieter, smoother drive. One tube treats up to 8 liters of ATF fluid, extending transmission life and boosting wear resistance in everyday driving from -20°C cold starts to 120°C high-heat conditions.

When to Use / Replace?

Add during every ATF change every 60,000 km or 4 years to maintain seals and prevent issues. Use if you notice slipping gears, whining noise, or leaks - mix via dipstick for quick revival. Shelf life is 4 years unopened; store cool and dry. Ideal preventive care before summer heat or winter cold extremes.
