Purpose and Specifications

RAVENOL 1211127-020-01-999 is a fully synthetic automatic transmission fluid (ATF) designed for Mercedes-Benz 7G-TRONIC transmissions with ECO Stop-Start function (NAG2FE+). This 20-liter drum delivers maximum wear protection, smooth shifting, and reliable performance in demanding conditions.

It flows easily at low winter temperatures down to -40°C for quick starts and stays thick at high operating temps up to 150°C, preventing breakdowns and extending transmission life. Approved to MB 236.15 standards (A 001 989 77 03, A 001 989 78 03), plus ATF 134 FE, 134 ME, and 7134 FE specs, it fights corrosion, foaming, and oxidation for cleaner internals.

• Key Benefits: Superior lubrication reduces friction for effortless gear changes
• Excellent cooling keeps temps stable during towing or city driving
• High shear stability maintains protection over 100,000 km

When to Use / Replace?

Use this ATF in compatible Mercedes 7G-TRONIC ECO transmissions for everyday driving, highway runs, or heavy loads. Replace every 60,000-80,000 km or 4-5 years, or sooner if shifting feels rough, fluid is dark/burnt, or during major service. Shelf life is 5 years unopened in cool storage.

Warning: Not for older 5/7-speed non-ECO Mercedes transmissions (MB 236.10/12/14).
