The different kind of automatic gearbox of a GMC Acadia

.
Gearboxes have the advantage of being reputed to be solid, as you don’t need to use your clutch pedal and everything is electronically and mechanically handled there will be no early wear of your clutch or other elements that could be put to the test by misuse on your part.
However, depending on the kind of automatic transmission your GMC Acadia is equipped with you will have more or less reliability, we will introduce 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 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 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 elevated 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 GMC Acadia.

I’m having complications with the automatic transmission on my GMC Acadia

As described earlier, generally they are more reliable than manual transmissions, nevertheless, here are the main complications you may face:

  • As mentioned over, no matter what kind of automatic gearbox, they are quite often known 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 constantly, the clutch or converter is probably dead.
  • I have the feeling that a gear in the automatic transmission of my GMC Acadia no longer shifts or jumps: If you have the feeling that your gears no longer shift or often jump on your GMC Acadia, there is a part that is most certainly responsible 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 unit speed sensor may be defective and send the wrong information to your gearbox.
  • If you experience drops coming from the automatic gearbox of your GMC Acadia: 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
