The different sort of automatic gearbox of a Mercedes Classe B

.
Gearboxes have the benefit of being known to be trustworthy, as you don’t need to use your clutch pedal and everything is electronically and mechanically managed there will be no early wear of your clutch or other components that could be put to the test by misuse on your component.
Nevertheless, based on the type of automatic transmission your Mercedes Classe B is equipped with you will have more or less reliability, we will present them to you now:

  • Classic automatic gearbox: It will use a torque converter, which will manage the gear changes, it’s the oldest technology, it has evolved a lot in the last decades (more gears and a better management of the gear changes).
  • Robotized automatic gearbox: This is a manual gearbox with a robotized mechanism that will change the driver’s action. This type of gearbox is less and less general because they are viewed as very slow. We as well quite often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the ultimate automatic transmission, it works on the same concept as the robotic transmission, but thanks to its dual clutch, you won’t have any more complications with slow speeds or elevated fuel consumption. They are often fitted on luxury models.
  • Continuously variable automatic box: It is the same concept as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are really slow and tend to be unresponsive during the acceleration phases of your Mercedes Classe B.

  • If you experience drops coming from the automatic gearbox of your Mercedes Classe B: If you experience a clutch when you go up or when you slow down, it is either your oil which is too old and which does not lubricate any more adequately all the mechanisms of your gearbox, or else a sensor which gives bad info
