It delivers smooth shifting, excellent wear protection, and reliable performance in 5-speed and 7-speed automatic transmissions, meeting MB-Approval 236.14 and recommended for MB 236.12.

This 1-liter carton protects against corrosion, prevents foam, and maintains stability from -48°C cold starts to high-heat conditions over 210°C. It ensures precise gear changes under extreme loads, extending transmission life with superior oxidation resistance.

• Perfect for Mercedes transfer boxes and hydraulics

When to Use / Replace?

Use during transmission service or to fix shifting issues like hesitation or harsh engages. Replace every 60,000-100,000 km or 4-5 years, whichever comes first, based on Mercedes intervals. Ideal for harsh conditions like heavy traffic or hot climates where fluid breaks down faster.

Shelf life is 5 years unopened in cool, dry storage. Always check dipstick for dark color or burnt smell before changing.
