Purpose and Specifications

Liqui Moly 21379 Top Tec ATF 1950 is a premium automatic transmission fluid in a 20-liter canister, specially formulated for Mercedes-Benz vehicles requiring MB 236.17 specification. It delivers smooth shifting, protects against wear, and maintains performance in engines from 88-639 horsepower built between 2003-2026.

This low-viscosity oil reduces fuel consumption, offers excellent temperature stability from -40°C cold starts to over 150°C high-heat operation, and ensures high efficiency with superior friction properties for maximum transmission life.

When to Use / Replace?

Use this transmission oil during service intervals every 60,000-100,000 km or 4-5 years, depending on your Mercedes-Benz model like C-Class, E-Class, or 4MATIC variants. Replace if you notice rough shifting, slipping gears, or delayed engagement, especially in heavy towing or high-mileage driving.

Shelf life is 5 years unopened when stored in a cool, dry place. Ideal for workshops handling fleet maintenance with its large 20L size.
