Purpose and Specifications

WOLF OFFICIALTECH ATF 9G is a synthetic automatic transmission fluid engineered specifically for Mercedes-Benz 9-gear automatic transmissions, including the latest 9G-Tronic (W9A 700 series) and NAG3 transmissions. This fluid meets the MB 236.17 specification and is backward compatible with MB 236.16.

The fluid is formulated with premium base oils and advanced additives to deliver smooth gear shifting without vibration, excellent wear protection, and superior thermal stability. It flows easily even in cold conditions (pour point of -45°C) while maintaining consistent performance at high operating temperatures, ensuring your transmission stays protected in all driving conditions.

When to Use / Replace?

Follow your Mercedes-Benz owner's manual for specific service intervals, which typically range from 60,000 to 100,000 kilometers or every 4 to 6 years, whichever comes first. Check your transmission fluid level regularly—low fluid can cause rough shifting, overheating, and transmission damage.

Use this fluid if your vehicle requires MB 236.17 specification. Always consult your vehicle's service documentation before adding or replacing transmission fluid.

Key Benefits

• Maintains stable performance across a wide temperature range (-45°C to over 100°C operating)
• Excellent oxidation and thermal stability prevents fluid breakdown
• Backward compatible with earlier MB 236.16 specification
• Synthetic formula provides superior protection compared to conventional fluids

Frequently Asked Questions

Q: Can I use this fluid in non-Mercedes vehicles?
A: No. This fluid is specifically formulated for Mercedes-Benz automatic transmissions. Using the wrong fluid can damage your transmission. Always check your vehicle's manual for the correct specification.

Q: How do I know if my transmission fluid needs replacement?
A: Signs include rough or delayed gear shifts, transmission overheating, or a burnt smell. However, the best approach is to follow your manufacturer's service schedule. Regular fluid checks help catch problems early.

Q: Is synthetic transmission fluid better than conventional?
A: Yes. Synthetic fluids like OFFICIALTECH ATF 9G offer better thermal stability, longer service life, and superior protection across a wider temperature range, which is especially important for modern 9-gear transmissions that operate under demanding conditions.
