Purpose and Specifications

RAVENOL ATF M 9-FE Serie 4L is a fully synthetic automatic transmission fluid designed for Mercedes 7G-TRONIC transmissions with ECO Stop-Start (NAG2FE+) from 2010 onwards. This blue fluid delivers maximum wear protection, flows easily in cold winter starts down to -42°C for smooth shifting, and maintains stable thickness during hot drives up to high operating temperatures.

It meets official MB 236.15 approval plus ATF 7134 FE, ATF 134 ME, and ATF 134 FE specs, ensuring perfect gearbox function, excellent cooling, and resistance to corrosion and foam. The low-viscosity formula reduces fuel use while providing superior oxidation stability for long-term reliability.

When to Use / Replace?

• Use in Mercedes vehicles with 7G-TRONIC NAG2FE+ ECO Stop-Start transmissions (check your owner's manual or VIN for confirmation).
• Replace every 60,000-100,000 km or 4-5 years under normal driving; sooner at 40,000 km for heavy towing or city stop-go traffic.
• Ideal for cold climates (flows at -42°C) and hot conditions (stable at 120°C+); shelf life is 5 years unopened.
• Flush completely if switching from older red ATF to avoid mixing issues.

FAQ

Is this the right fluid for my pre-2010 Mercedes? No, use RAVENOL ATF M 9 Serie (red) for earlier 7G-TRONIC models. Always verify your transmission type.

How much fluid does a typical Mercedes 7G-TRONIC need? Around 8-9 liters for a full flush; this 4L pack covers half, perfect for top-ups or partial services.

Can I use it in non-Mercedes cars? Only if specs match MB 236.15 exactly; check your manual to prevent shifting problems or damage.
