Purpose and Specifications

EUROLUB GEAR FLUIDE II D is a premium automatic transmission fluid (ATF) engineered for modern automatic and semi-automatic transmissions in passenger cars, light commercial vehicles, and industrial machinery. This red fluid meets GM DEXRON IID specifications and is also suitable for hydrostatic transmissions, power steering systems, and torque converters.

The fluid delivers outstanding thermal stability, meaning it maintains consistent performance across a wide temperature range—from cold winter starts to hot highway driving. Its high viscosity index ensures the oil flows smoothly when cold and maintains protective thickness when hot, protecting internal transmission components from wear.

• Excellent oxidation resistance: Prevents fluid breakdown and sludge buildup over time, extending transmission life
• Superior friction properties: Optimized for General Motors Hydramatic transmissions, ensuring smooth gear shifts and responsive performance
• Corrosion protection: Guards against rust and degradation of metal transmission parts
• Anti-foaming formula: Prevents air bubbles that can reduce hydraulic pressure and cause shifting problems

When to Use / Replace?

Use EUROLUB GEAR FLUIDE II D in any automatic transmission, power steering system, or hydraulic application requiring GM DEXRON IID fluid. Check your vehicle's owner manual for the exact specification required.

Replacement intervals: Most automatic transmissions require fluid checks every 40,000 km or annually. Full fluid changes typically occur every 80,000–160,000 km, depending on driving conditions and manufacturer recommendations. Severe driving (towing, frequent city driving) may require more frequent changes.

Operating temperature range: This fluid performs reliably from approximately -46°C (cold start protection) to +182°C (flash point safety margin), covering virtually all climate conditions.

Shelf life: Store in a cool, dry location. Unopened containers remain stable for several years when properly sealed.

Frequently Asked Questions

Q: Can I mix EUROLUB GEAR FLUIDE II D with other ATF brands?
A: No. Always use the same fluid type specified in your vehicle manual. Mixing different ATF types can reduce performance and damage transmission seals. If switching brands, drain and flush the system completely.

Q: How do I know if my transmission fluid needs replacing?
A: Check the dipstick or electronic level indicator monthly. The fluid should be bright red and smell slightly sweet. Dark brown or burnt-smelling fluid indicates it needs replacement immediately. Also follow your vehicle manufacturer's recommended service intervals.

Q: Is this fluid suitable for CVT or dual-clutch transmissions?
A: No. DEXRON IID fluid is designed for traditional automatic transmissions only. CVTs and dual-clutch transmissions require specialized fluids—check your owner's manual for the correct type.
