Check Engine


The automatic gearbox with oil-bath friction clutch is combined with a torque converter which acts as a clutch. This type of gearbox was developed after the Second World War, and will long remain the only alternative to the mechanical gearbox.

Over time, the clutch discs wear out, generating particles that clog the hydraulic block and cause jerking and slipping when revving up.

The first G-Tronic was a 4-speed automatic gearbox launched in 1981. The manufacturer, DAIMLER AG, still produces a 9-speed version. Like the manumatic Tiptronic S from the Porsche/VAG group, the G Tronic will evolve over time into a manual/sequential version, with additional functions such as Sport, Comfort or Eco mode.
