Gearboxes have the advantage of being reputed to be trustworthy, as you don’t need to use your clutch pedal and every thing is electronically and mechanically managed there will be no premature wear of your clutch or other parts that could be put to the test by misuse on your component.
Nevertheless, based on the kind of automatic transmission your GMC Yukon is equipped with you will have more or less reliability, we will present them to you now:

  • Common automatic gearbox: It will use a torque converter, which will control 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 change the driver’s action. This kind of gearbox is less and less common because they are viewed as very slow. We also often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the greatest automatic transmission, it works on the same concept as the robotic transmission, but thanks to its dual clutch, you won’t have any more complications with slow speeds or increased fuel consumption. They are often equipped on luxury models.
  • Continuously variable automatic box: It is the same concept 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 Yukon.
