The different sort of automatic gearbox of a Lexus ES

.
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 managed there will be no premature wear of your clutch or other components that could be put to the test by misuse on your part.
However, depending on the type of automatic transmission your Lexus ES is equipped with you will have more or less reliability, we will expose 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 system that will change the driver’s action. This type of gearbox is less and less general because they are thought to be very slow. We also often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the best 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 increased fuel consumption. They are often equipped on luxury models.
  • Continuously variable automatic box: It is similar theory as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are particularly slow and often be unresponsive during the acceleration phases of your Lexus ES.

  • If you experience drops originating from the automatic gearbox of your Lexus ES: If you experience 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 information
