Mercedes W212 E-Class 7G-Tronic Harsh Cold Shifting
The 7G-Tronic gearbox on W212 shifts harshly from cold, particularly between first and second gear. This is often fluid-related — degraded transmission fluid causes incorrect hydraulic pressure at cold temperatures. A fluid change resolves most cases. If harsh shifting persists when warm, valve body wear or conductor plate failure is the cause.
