The different kind of automatic gearbox of a Lexus NX

.
Gearboxes have the benefit of being reputed to be reliable, as you don’t need to use your clutch pedal and everything is electronically and mechanically controlled 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 Lexus NX 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 control 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 type of gearbox is less and less common because they are viewed as very slow. We as well quite often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the best automatic transmission, it works on similar principle 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 fitted 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 tend to be unresponsive during the acceleration phases of your Lexus NX.

Nevertheless, this phenomenon is supposed to occur only when the car is started, not when it is launched. If it feels like it comes about constantly, the clutch or converter is likely dead.
  • I have the feeling that a gear in the automatic transmission of my Lexus NX no longer shifts or jumps: If you have the feeling that your gears no longer shift or tend to jump on your Lexus NX, there is a component that is most likely to blame for this failure. Obviously, 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 faulty and send the wrong information to your gearbox.
  • If you feel drops coming from the automatic gearbox of your Lexus NX: 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
