Purpose and Specifications

The COMLINE COATF3H-1 Automatic Transmission Fluid is a 1-liter synthetic ATF Dexron III H oil designed for smooth shifting and long-lasting protection in automatic transmissions. This budget-friendly high-performance fluid uses advanced synthetic technology to reduce wear, prevent foaming, and maintain stability under heat, keeping your gearbox running cool and efficient from -40°C to over 150°C.

• Protects clutches and gears for reliable performance in Ford and GM vehicles (pre- and post-1997 models).
• Resists oxidation to avoid sludge buildup, extending transmission life up to 100,000 km or 5 years.
• Shelf life: 3-5 years unopened in cool, dry storage.

When to Use / Replace?

Use this fluid for routine maintenance or when repairing automatic transmissions in compatible Ford Kuga, Mercedes-Benz, and GM vehicles. Replace every 60,000-80,000 km or every 3-4 years, or sooner if you notice slipping gears, harsh shifts, or burnt smell—early change prevents costly repairs.
