Purpose and Specifications

WOLF OFFICIALTECH ATF 9G 5L is a fully synthetic automatic transmission fluid designed specifically for Mercedes-Benz 9-speed 9G-Tronic transmissions (W9A 700 series, also called NAG3). It meets the strict MB 236.17 specification and is backward compatible with MB 236.17 transmissions, ensuring smooth gear shifts, excellent wear protection, and reliable performance in every driving condition.

This budget-friendly oil flows easily at low temperatures down to -45°C for quick cold starts without sluggishness, while staying thick and protective up to high operating temps around 200°C. The 5-liter canister is perfect for complete transmission flushes, keeping your gearbox running like new with superior corrosion resistance and stable lubrication over tens of thousands of kilometers.

When to Use / Replace?

Use this oil in Mercedes-Benz vehicles with 9G-Tronic automatics requiring MB 236.17 approval. Replace every 60,000 to 100,000 km or 4-5 years, whichever comes first, especially if you notice rough shifting, delayed engagement, or slipping gears. It's ideal for daily commuting, highway driving, or towing where transmissions face heavy loads. Shelf life is 3-5 years when stored in a cool, dry place.

Key Benefits:

• Smooth, precise shifting even in freezing cold or scorching heat
• Reduces wear for longer transmission life
• Prevents corrosion and sludge buildup
• Compatible with older MB 236.16 spec transmissions
