Learning to drive a car is not constantly unproblematic, and sometimes it may seem like a good solution to choose an automatic GMC Terrain, if it’s for simple convenience or ease of use, this type of transmission is becoming more and more known. However, although they might seem like an excellent choice, there may also be complications with the automatic gearboxes of your GMC Terrain . This is exactly the topic of our content page. First, we’ll quickly explain the different types of automatic gearboxes, then, in a second step, which complications you may face with the gearbox of your GMC Terrain , and, at last, how to solve them.

The different kind of automatic gearbox of a GMC Terrain

.
Gearboxes have the benefit of being known to be reliable, as you don’t need to use your clutch pedal and every thing is electronically and mechanically handled 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, based on the type of automatic transmission your GMC Terrain 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 manage 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 replace the driver’s action. This type of gearbox is less and less common because they are considered very slow. We also quite often feel a coupling during deceleration.
  • Dual-clutch automatic transmission: This is the greatest automatic transmission, it functions 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 equipped 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 particularly slow and often be unresponsive during the acceleration phases of your GMC Terrain.

I’m having complications with the automatic transmission on my GMC Terrain

We now start the part that definitely attracts you the most in this post, what are the complications you may face with the automatic transmission of your GMC Terrain? As mentioned above, generally speaking they are more reliable than manual transmissions, however, here are the main complications you may face:

  • As described earlier, no matter what type of automatic gearbox, they are quite often known to be slow and have inertia when accelerating. However, this phenomenon is designed to occur only when the car is started, not when it is launched. If it feels like it occurs all the time, the clutch or converter is almost certainly dead.
  • I have the feeling that a gear in the automatic transmission of my GMC Terrain no longer shifts or jumps: If you have the feeling that your gears no longer shift or often jump on your GMC Terrain, there is a part that is undoubtedly to blame for this failure. In fact, the solenoid that acts as a “switch” to engage the gears must not be functioning properly, 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 GMC Terrain: 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

    • .

  • My GMC Terrain’s automatic transmission is leaking: At last, if your GMC Terrain’s automatic transmission is leaking, it’s most likely one of your spy seals is too worn.

How do I fix automatic transmission complications on a GMC Terrain?

And finally, we’re going to try to give you the techniques to correct the automatic transmission complications on your GMC Terrain . Find them below:

  • Oil leak on the automatic gearbox of a GMC Terrain: Locate the origin of the leak, and replace the concerned gasket, get it done by a specialist, opening a gearbox is not easy. It will cost you a few hundred euros, specifically for the labour. Do not think twice to read our content page on gearbox oil leaks on GMC Terrain.
  • Sensor issue: No matter which sensor is concerned, a replacement is the only remedy, sensors do not repair themselves, you should count from 100 to a few hundred euros depending on the difficulty of access to the one that concerns you.
  • Couplings: If you have complications with the couplings on your GMC Terrain, you will only need to do a complete gearbox change to gain comfort and preserve your gears.
  • The automatic gearbox of my GMC Terrain slips: In this case, you certainly have a dead clutch disc, you will have to change the clutch, and on some models you won’t be able to change it without doing a standard exchange of the gearbox, be prepared to spend more than a thousand euros.

There are other automatic transmission complications on GMC Terrain, such as electronic problems or pressure complications, but this list lists the main ones, whatever the case, for such difficult mechanisms. As soon as you feel a problem on this level, we recommend you to go fairly quickly to your mechanic.
