Learning to drive a vehicle is not all the time unproblematic, and occasionally it may seem like a good solution to choose an automatic Kia Sedona, whether it’s for basic comfort or ease of use, this type of transmission is becoming more and more known. However, while they might seem like an excellent solution, there may possibly as well be problems with the automatic gearboxes of your Kia Sedona . This is exactly the subject of our content page.

The different types of automatic gearbox of a Kia Sedona

.
Gearboxes have the benefit of being known to be solid, as you don’t need to use your clutch pedal and every thing is electronically and mechanically controlled there will be no early wear of your clutch or other parts that could be put to the test by misuse on your part.
However, depending on the type of automatic transmission your Kia Sedona 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 mechanism 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 functions on similar principle as the robotic transmission, but thanks to its dual clutch, you won’t have any more problems with slow speeds or increased fuel consumption. They are often fitted 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 really slow and often be unresponsive during the acceleration phases of your Kia Sedona.

I’m having problems with the automatic transmission on my Kia Sedona

We now start the part that absolutely attracts you the most in this post, what are the problems you may face with the automatic transmission of your Kia Sedona? As outlined above, in general they are more reliable than manual transmissions, however, here are the most important problems you may come across:

  • As described above, no matter what type of automatic gearbox, they are quite often known to be slow and have inertia when accelerating. However, this phenomenon is supposed to appear only when the car is started, not when it is launched. If it feels like it occurs all the time, the clutch or converter is most certainly dead.
  • I have the feeling that a gear in the automatic transmission of my Kia Sedona no longer shifts or jumps: If you have the feeling that your gears no longer shift or often jump on your Kia Sedona, there is a part that is undoubtedly responsible for this failure. In truth, the solenoid that acts as a “switch” to engage the gears must not be functioning properly, second option, a speed or engine speed sensor may be faulty and send the wrong information to your gearbox.
  • If you experience drops caused by the automatic gearbox of your Kia Sedona: 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 information

  • My Kia Sedona’s automatic transmission is leaking: At last, if your Kia Sedona’s automatic transmission is leaking, it’s most probably one of your spy seals is too worn.

How do I fix automatic transmission problems on a Kia Sedona?

And finally, we’re going to try to give you the strategies to fix the automatic transmission problems on your Kia Sedona . Find them below:

  • Oil leak on the automatic gearbox of a Kia Sedona: Locate the source of the leak, and change the concerned gasket, get it done by a specialist, opening a gearbox is not easy. It will cost you a few hundred euros, especially for the labour. Do not think twice to read our content page on gearbox oil leaks on Kia Sedona.
  • Sensor problem: No matter which sensor is concerned, a replacement is the only solution, sensors do not repair themselves, you should count from 100 to a few hundred euros depending on the difficulty of access to the one that concerns you.
  • Couplings: If you have problems with the couplings on your Kia Sedona, you will only need to do a complete gearbox change to gain comfort and preserve your gears.
  • The automatic gearbox of my Kia Sedona slips: In this case, you clearly have a dead clutch disc, you will have to change the clutch, and on some models you won’t be able to change it without doing a standard exchange of the gearbox, be prepared to spend more than a thousand euros.

There are other automatic transmission problems on Kia Sedona, such as electronic problems or pressure problems, but this list lists the most important ones, whatever the case, for such complex mechanisms. Once you feel a problem on this level, we recommend you to go fairly quickly to your mechanic.
