The different sort of automatic gearbox of a Renault Koleos

.
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 managed there will be no early 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 Koleos is equipped with you will have more or less reliability, we will expose 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 quite 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 system that will change the driver’s action. This sort of gearbox is less and less common because they are considered very slow. We also quite often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the greatest automatic transmission, it functions on similar principle as the robotic transmission, but thanks to its dual clutch, you won’t have any more complications with slow speeds or increased fuel consumption. They are often equipped on luxury models.
  • Continuously variable automatic box: It is similar theory as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are especially slow and often be unresponsive during the acceleration phases of your Renault Koleos.

I’m having complications with the automatic transmission on my Renault Koleos

We now start the component that definitely attracts you the most in this post, what are the complications you may encounter with the automatic transmission of your Renault Koleos? As outlined above, generally they are more reliable than manual transmissions, nevertheless, here are the most important complications you may come across:

  • As described over, no matter what sort of automatic gearbox, they are quite often established to be slow and have inertia when accelerating. However, this phenomenon is supposed to happen only when the vehicle is started, not when it is launched. If it feels like it comes about all the time, the clutch or converter is almost certainly dead.
  • I have the impression that a gear in the automatic transmission of my Renault Koleos no longer shifts or jumps: If you have the impression that your gears no longer shift or often jump on your Renault Koleos, there is a component that is most certainly to blame for this failure. In fact, the solenoid that acts as a “switch” to engage the gears must not be working properly, second option, a speed or engine speed sensor may be defective and send the wrong information to your gearbox.
  • If you feel drops coming from the automatic gearbox of your Renault Koleos: If you feel 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
