The different kind of automatic gearbox of a Toyota Avalon

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 parts that could be put to the test by misuse on your part.
Nevertheless, based on the kind of automatic transmission your Toyota Avalon is equipped with you will have more or less reliability, we will introduce 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 system that will replace the driver’s action. This kind of gearbox is less and less general because they are viewed as very slow. We also often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the ultimate automatic transmission, it works 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 equipped 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 Toyota Avalon.
