The different kind of automatic gearbox of a Hyundai Sonata

.
Gearboxes have the benefit of being known to be reliable, 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 parts that could be put to the test by misuse on your component.
However, depending on the kind of automatic transmission your Hyundai Sonata 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 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 replace the driver’s action. This kind 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 greatest automatic transmission, it works on similar principle 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 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 Hyundai Sonata.

I’m having complications with the automatic transmission on my Hyundai Sonata

We now begin the component that absolutely attracts you the most in this post, what are the complications you may encounter with the automatic transmission of your Hyundai Sonata? As explained above, in general they are more reliable than manual transmissions, however, here are the main complications you may come across:

  • As mentioned over, no matter what kind of automatic gearbox, they are quite often established to be slow and have inertia when accelerating. However, this phenomenon is supposed to happen just when the car is started, not when it is launched. If it feels like it comes about constantly, the clutch or converter is most likely dead.
  • I have the impression that a gear in the automatic transmission of my Hyundai Sonata no longer shifts or jumps: If you have the impression that your gears no longer shift or tend to jump on your Hyundai Sonata, there is a component that is most certainly to blame for this failure. In actual fact, the solenoid that works as a “switch” to engage the gears must not be functioning effectively, second option, a speed or engine speed sensor may be defective and send the wrong information to your gearbox.
  • If you experience drops originating from the automatic gearbox of your Hyundai Sonata: 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

  • My Hyundai Sonata’s automatic transmission is leaking: Finally, if your Hyundai Sonata’s automatic transmission is leaking, it’s most probably one of your spy seals is too worn.
