Purpose and Specifications

MOTOREX ATF DEXRON III is a synthetic automatic transmission fluid designed for modern automatic gearboxes, power steering systems, and select manual transmissions that require ATF. This 4-liter container meets the demanding GM DEXRON III H specification and is approved for use in vehicles from major manufacturers including Ford, Volkswagen, Mercedes-Benz, Allison, Caterpillar, and ZF.

The fluid delivers superior wear and corrosion protection, keeping internal transmission components clean and functioning smoothly. Its advanced formula maintains consistent performance across a wide temperature range, from cold winter starts down to -40°C to high-heat highway driving conditions. The oil resists breakdown and maintains its protective properties over extended service intervals, reducing the need for frequent fluid changes.

Key Benefits

• Smooth, precise gear shifts – Ensures clean engagement and reduces shift hesitation
• Extended transmission life – Protects against wear, corrosion, and oxidation damage
• Cold-weather performance – Flows easily at low temperatures for reliable winter operation
• Thermal stability – Maintains protection even during heavy towing or stop-and-go driving
• Broad compatibility – Works in automatic transmissions with or without torque converters, power steering, and hydraulic systems

When to Use / Replace?

Initial fill: Use MOTOREX ATF DEXRON III when servicing or replacing transmission fluid in compatible vehicles. Always consult your vehicle's owner manual for the correct fluid specification before use.

Replacement intervals: Most modern automatic transmissions require fluid changes every 40,000 to 80,000 kilometers or every 2 to 4 years, depending on driving conditions and manufacturer recommendations. Severe driving (towing, frequent city driving, or extreme temperatures) may require more frequent changes.

Storage: Keep the sealed 4-liter container in a cool, dry location. Unopened fluid maintains its quality for several years when stored properly away from direct sunlight and temperature extremes.

Frequently Asked Questions

Q: Can I use this fluid in my manual transmission?
A: MOTOREX ATF DEXRON III is suitable for manual gearboxes that specifically require ATF fluid. Check your vehicle's manual first – many manual transmissions use different gear oils and should not use ATF.

Q: Is this fluid synthetic?
A: Yes, MOTOREX ATF DEXRON III is a high-performance synthetic fluid that offers superior oxidation stability, longer service life, and better protection compared to conventional mineral-based transmission fluids.

Q: What's the difference between DEXRON III and older DEXRON II?
A: DEXRON III provides improved cold-weather flow, better shifting performance, and enhanced thermal stability compared to the older DEXRON II specification. It's the modern standard for most automatic transmissions built in the last 15+ years.
