  • 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 replace the driver’s action. This sort of gearbox is less and less common because they are thought to be very slow. We also quite 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 fitted 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 really slow and tend to be unresponsive during the acceleration phases of your Lexus GX.
