7G-Tronic Transmission

The 722.9 is a 7-speed automatic with electronic controls and adaptive learning. It provides refined shifting but can develop issues requiring specific diagnosis.

Common Transmission Problems

Conductor Plate Failure

Valve Body Issues

The valve body controls hydraulic routing. Wear or contamination causes pressure variations affecting shift quality.

Fluid Degradation

The 7G-Tronic requires specific Mercedes-approved fluid. Degradation or wrong fluid causes shift quality problems.

Adaptation Corruption

The transmission learns clutch characteristics. Corrupted adaptation values cause inconsistent shifting.

Service Requirements

Mercedes doesn't consider the transmission "sealed for life." Commercial use demands periodic fluid service.
