Purpose and Specifications

ALCO FILTER DEXRON III G is an automatic transmission fluid designed for General Motors vehicles and a wide range of other manufacturers requiring Dexron III G performance. This fluid keeps your transmission running smoothly by reducing wear on internal components, maintaining consistent shift quality, and protecting against rust and corrosion.

This budget-friendly option meets specifications for Allison C4, Mercedes-Benz (MB 236.1, MB 236.5), ZF transmissions (TE-ML 02F, 03D, 04D, 11B, 14A), and MAN transmissions, making it compatible with a broad range of vehicles from the 1990s through early 2000s.

Key Performance Features:

• Smooth gear shifts with controlled friction properties
• Protects transmission components at operating temperatures up to 120°C
• Excellent cold-start performance, flowing easily at temperatures as low as -40°C
• Resists oxidation and thermal breakdown, maintaining fluid integrity over time
• Prevents rust and corrosion on steel and copper transmission parts
• Compatible with all common transmission seal materials

When to Use / Replace?

Use ALCO FILTER DEXRON III G in automatic transmissions, torque converters, and power steering systems that specify Dexron III G performance. For most vehicles, transmission fluid should be checked every 40,000 km and replaced every 80,000 to 160,000 km, depending on driving conditions and manufacturer recommendations. Severe driving conditions (frequent towing, city driving with stop-and-go traffic) may require more frequent changes.

This 1-liter bottle is ideal for topping up fluid levels between full services or for smaller transmission systems. Store in a cool, dry location away from direct sunlight. Shelf life is typically 3-5 years when properly stored.

Frequently Asked Questions

Q: Can I mix DEXRON III G with other transmission fluids?
A: DEXRON III G is backward compatible with earlier Dexron fluids and can be mixed with other Dexron III formulations. However, avoid mixing with newer Dexron VI or completely different fluid types like Mercon V without checking your vehicle's manual first.

Q: What color should the fluid be?
A: New DEXRON III G fluid is bright red. If your fluid appears dark brown or black, it indicates oxidation and degradation—time for a fluid change. Dark red with a burnt smell suggests overheating or contamination.

Q: Is DEXRON III G suitable for modern vehicles?
A: DEXRON III G is designed for vehicles from the 1990s through early 2000s. Modern vehicles (post-2010) typically require newer specifications like Dexron VI or manufacturer-specific fluids. Always check your owner's manual to confirm compatibility.
