Toyota ATF Dexron III - Premium Automatic Transmission Fluid

Purpose and Specifications

Toyota ATF Dexron III is a premium automatic transmission fluid engineered to meet GM Dexron III performance standards. This fluid is designed for smooth, reliable gear shifting in automatic transmissions while protecting internal components from wear and corrosion.

Key Performance Benefits:

• Smooth and quiet gear shifts with excellent frictional properties
• Enhanced protection against wear, extending transmission life
• Superior corrosion and rust protection for gears, bushings, and clutch plates
• Improved low-temperature fluidity for cold-start protection
• Better thermal stability to resist breakdown at high operating temperatures (typically 60–100°C during normal driving)
• Compatible with all common seal materials for versatile use

Recommended for: Toyota automatic transmissions (most models prior to 2002), as well as many other vehicles specifying Dexron III or Mercon fluid standards.

When to Use / Replace?

Check your vehicle's owner manual for the exact replacement interval. Typical automatic transmission fluid changes occur every 40,000–80,000 km or every 2–4 years, depending on driving conditions and transmission type. Replace sooner if fluid appears dark, smells burnt, or shows signs of contamination. Always use the exact fluid specification your vehicle manufacturer recommends.
