The different kind of automatic gearbox of a Renault Laguna 3

.
Gearboxes have the advantage of being known to be trustworthy, as you don’t need to use your clutch pedal and every thing is electronically and mechanically controlled there will be no premature wear of your clutch or other parts that could be put to the test by misuse on your component.
However, depending on the sort of automatic transmission your Renault Laguna 3 is equipped with you will have more or less reliability, we will introduce them to you now:

  • Common 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 replace the driver’s action. This sort of gearbox is less and less basic because they are considered 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 similar concept as the robotic transmission, but thanks to its dual clutch, you won’t have any more problems with slow speeds or elevated fuel consumption. They are often equipped on luxury models.
  • Continuously variable automatic box: It is similar concept as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are particularly slow and often be unresponsive during the acceleration phases of your Renault Laguna 3.
