The different sort of automatic gearbox of a Chevrolet Avalanche

.
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 controlled there will be no premature 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 Chevrolet Avalanche 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 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 replace the driver’s action. This type of gearbox is less and less general 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 works on the same 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 equipped on luxury models.
  • Continuously variable automatic box: It is the same principle 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 Chevrolet Avalanche.
