Automatic transmission
Automatic transmissions, as their name suggests, change gears automatically. These systems no longer need the clutch pedal and will lead to easier driving. In these systems, the car does not need to be removed during on-site operation. For this reason, fuel consumption is slightly higher than manual transmissions at this time. Of course, when driving at high speeds, fuel consumption will be greatly reduced and economical.
Automatic transmission consists of several components such as automatic transmission clutch, automatic gears, car central computer (ECU) and torque converter. These systems have different models such as AMT gearbox, two clutch DCT, planetary AT and CVT. Of course, the appearance and mechanism of operation in all these models are almost similar to each other. So that all of them receive mechanical power from the engine and transfer it to the gearbox with the help of a torque converter. Then the power starts to rotate the gearbox shaft. In this way, the car moves at a certain speed.
Symptoms of gearbox failure
There are many signs that can tell you about the failure of the automatic transmission. These symptoms include:
A smell similar to burning oil around the car
The gear stick is out of place
There is vibration in the gearbox
The car does not move or its gearbox does not engage to move
There are noises Similar to whining, howling, or knocking when starting the car
Oil leaking from around the gearbox or reducing its oil level
The car engine warning light is on.
Factors affecting failure Automatic transmission
The most important factors that can lead to automatic transmission failure are sudden changes in its modes. For a better understanding of this matter, we will give some examples below:
When the car is idle and your foot is on the gas pedal, never put the gear lever in D, which means Drive.
Don’t select P, which means Park, before the car comes to a complete stop. />Do not change the gear box mode between P, R, N and D when the car is moving.
Avoid moving in neutral when driving downhill. Periodically check the automatic and change its oil on time.
