When to Use / Replace?

Use this ATF in older cars, trucks, and buses requiring Dexron II D specs, especially European models from ZF, Mercedes, or Voith. Perfect for high-mileage vehicles over 100,000 km needing refreshed fluid to prevent jerky shifting or overheating.

Replace every 40,000-60,000 km or every 24-36 months, or sooner if towing heavy loads or in extreme temps. Check fluid level monthly and change if dark or burnt-smelling.
