The different kind of automatic gearbox of a Mercury Mariner

.
Gearboxes have the benefit of being known to be solid, as you don’t need to use your clutch pedal and every thing is electronically and mechanically controlled there will be no premature wear of your clutch or other elements that could be put to the test by misuse on your component.
Nevertheless, depending on the sort of automatic transmission your Mercury Mariner is equipped with you will have more or less reliability, we will present them to you now:

  • Classic automatic gearbox: It will use a torque converter, which will control 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 viewed as very slow. We also quite often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the best automatic transmission, it works on similar 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 similar principle as on a scooter, a variator will come to control the differences between acceleration and motor speed, they are really slow and often be unresponsive during the acceleration phases of your Mercury Mariner.

  • I have the feeling that a gear in the automatic transmission of my Mercury Mariner no longer shifts or jumps: If you have the feeling that your gears no longer shift or often jump on your Mercury Mariner, there is a component that is most certainly to blame for this failure. Obviously, the solenoid that acts as a “switch” to engage the gears must not be functioning effectively, second option, a speed or engine unit speed sensor may be defective and send the wrong information to your gearbox.
  • If you experience drops coming from the automatic gearbox of your Mercury Mariner: 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
