The different types of automatic gearbox of a GMC Savana

.
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 managed there will be no premature wear of your clutch or other components that could be put to the test by misuse on your component.
However, depending on the kind of automatic transmission your GMC Savana is equipped with you will have more or less reliability, we will expose them to you now:

  • Common 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 mechanism that will change the driver’s action. This kind of gearbox is less and less common because they are considered very slow. We as well generally 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 problems with slow speeds or elevated fuel consumption. They are often fitted on luxury models.
  • Continuously variable automatic box: It is similar principle 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 GMC Savana.

  • As mentioned above, no matter what kind of automatic gearbox, they are generally established to be slow and have inertia when accelerating. However, this phenomenon is designed 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 GMC Savana no longer shifts or jumps: If you have the impression that your gears no longer shift or tend to jump on your GMC Savana, there is a component that is most likely responsible for this failure. In truth, 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 GMC Savana: 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
