It is known that modern cars are equipped with an automatic transmission system instead of the manual one that was once the most widespread in the automotive world, and the automatic transmission is now the most desired among drivers, and there is even a whole generation of drivers who have never driven a car with a manual transmission in their entire lives.
Because of an automatic transmission systems are becoming more and more widespread, they have become sophisticated and equipped with their own system to detect malfunctions and inform the driver about them through a warning system or a sign that appears in the dashboard next to the signs of other car systems.
Since the transmission is an essential and important part of every car, it is necessary for it to be intact and free of malfunctions all the time, especially when you want to buy a used car, but don't worry; because Motorgy has a large selection of used cars for sale in Kuwait that are inspected for you to choose your dream car from, and you are happy for many years to come.

Why the Automatic transmission warning light appears?
There are several reasons for the appearance of the Automatic transmission light in the dashboard, which are:
Overheating
The issue of overheating is one of the most important reasons that lead to issues with the automatic transmission, so it is necessary to make sure that the cooling system in your car is working properly to cool the engine as it should, and to check the level of the transmission oil to be within the normal limit, and you must immediately check for any signs of overheating of the transmission or engine and pay attention to the warning lights in front of you at all times and deal with them seriously if they appear in front of you.
Lack of oil
When the oil level is low, whether due to age or leakage, many cars display a low oil warning light to let you know the level is low and may be accompanied by a message telling you that the oil level is low and you should refill it as soon as possible.
Damage to one of the internal parts
The automatic transmission contains many complex internal components, such as gear sets, turbines, torque converters and others, and when any malfunction occurs in one of these components, the car's computer will detect this malfunction and send a warning signal that appears in the dashboard, and the signal may be specific to the transmission or the check engine light may appear in somewhat older cars.

Clutch problems
It is important to know that the transmission warning light may not always indicate an issue with the transmission itself, but with the parts connected to it or responsible for its movement, such as the clutch, for example, as a malfunction in the transmission interlock system designed to prevent changing gears without pressing the brake pedal, and here the gear may make a sound and be accompanied by its warning light.
Valve Body problems
Most CVTs and regular automatic transmissions feature a valve that regulates the flow of oil to various internal components, and modern valves often incorporate control units and electronic parts, and if your car's transmission fails and the warning light comes on, it could be due to a damaged valve.
Torque converter issue
Many transmission systems contain torque converters, which act as oil and motion couplers between the transmission and the engine, and issues can arise with these converters such as clutch issues that lead to friction and vibration, and if the issue is significant, the damaged converter may disintegrate, which may affect the transmission and cause its warning light to appear.

Sensors Problems
Transmission systems in cars are powered by a control unit that receives data from different sensors and communicates with other units through a data network. If this unit, one of the sensors, or any other electronic component is damaged, the warning light may appear. In addition, electrical issues such as faulty wiring or a faulty solenoid can also cause the warning light to appear.
Unusual Noise
If you hear a loud squeak or noise that you're not used to hearing coming from the engine area while driving or shifting gears, it's often due to an issue with the transmission. This could be due to a lack of oil or even a clogged filter in the transmission, but it could also indicate an impending transmission failure that you should prepare for.
