Purpose and Specifications

LIQUI MOLY Top Tec ATF 1600 is a fully synthetic automatic transmission fluid designed for Mercedes-Benz 7-speed (1st generation up to June 2010) and older 5-speed transmissions. It delivers excellent wear resistance to protect gears from grinding during shifts, superior corrosion protection to prevent rust in harsh conditions, and stays fluid in cold starts down to -40°C while maintaining thickness up to 150°C for smooth operation in extreme heat.

This premium 1L fluid ensures precise shifting, eliminates jerking or hesitation, and supports extremely long oil change intervals - typically every 100,000-160,000 km or 5-7 years under normal driving, depending on your Mercedes manual. Its foam-free formula keeps hydraulic pressure steady for reliable performance.

When to Use / Replace?

• Shifting problems: Hard shifts, slipping, or delays? This fluid fixes them by optimizing friction for crisp gear changes.
• Routine maintenance: Replace every 100,000 km or 5 years to maintain peak transmission life; check fluid level/color monthly - dark/burnt smell means immediate service.
• Extreme conditions: Ideal for towing, high-heat climates, or cold winters where standard ATF fails.

Shelf life is 5 years unopened when stored cool and dry. Always follow your Mercedes owner's manual for exact intervals.

FAQ

Q: Is this safe for my Mercedes 7G-Tronic transmission?
A: Yes, it has official MB-Approval 236.14 for 1st gen 7-speed (pre-2010) and MB 236.12 compatibility for 5-speed units - direct OEM match.

Q: How much fluid does a full transmission change need?
A: Typically 7-9 liters for a pan drop/filter change; full flush may need 12+ liters. Drain, measure old fluid, replace with equal amount.

Q: Can I mix with other ATF?
A: No - for best results, use undiluted. Flush system first if switching brands.
