The different types of automatic gearbox of a Lexus GS

.
Gearboxes have the benefit of being reputed to be trustworthy, as you don’t need to use your clutch pedal and every thing is electronically and mechanically handled there will be no early wear of your clutch or other components that could be put to the test by misuse on your component.
Nevertheless, depending on the kind of automatic transmission your Lexus GS 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 mechanism that will change the driver’s action. This kind of gearbox is less and less general because they are thought to be very slow. We as well 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 problems with slow speeds or increased fuel consumption. They are often fitted on luxury models.
  • Continuously variable automatic box: It is the same theory 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 Lexus GS.

  • I have the feeling that a gear in the automatic transmission of my Lexus GS no longer shifts or jumps: If you have the feeling that your gears no longer shift or often jump on your Lexus GS, there is a component that is undoubtedly responsible for this failure.

  • If you feel drops coming from the automatic gearbox of your Lexus GS: 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
