Is anyone not a fan of modern cars? There are more than enough valid incentives for the purchase of speed, comfort, Aesthetics, and versatility.
The safeguards put in place to make sure the proper functioning of the vehicle is there is the icing on the cake.
When you first see the AT light on your dashboard, it is unlikely that you are a Mazda owner.
What Is the AT Light?
Mazda vehicles have an AT light which stands for Automatic Transaxle light. It’s best to stop the car as soon as possible and take the vehicle for servicing when the light comes on.
You can be sure that the light will come back on soon, even if you ignore it because it might prove detrimental to your vehicle in the long run.
What Does It Mean When the AT Light Comes On?
There is a possibility of a fault with the automatic transmission of your car.
There can be other transmission issues that cause the light, but the most common cause is a low automatic transmission fluid level.
It is important to run checks on the car as soon as possible because there are a lot of problems that the AT light can indicate.
This could be the difference between the continued seamless function of the vehicle and the damage to the engine.
What To Do When the AT Light Comes on Your Mazda 3?
The AT warning light does not signal your vehicle’s death knell, and there are things an owner can do to fix the issue.
These are to be discussed below:
Check the Automatic Transmission Fluid Level
The transmission is the part of the car that converts the power from the engine to the moving force that pushes the car forward with the wheels.
The transmission fluid is important in this setup. Maintaining fluid pressure, lubricating, and preventing oxidation and rust are some of the tasks that it is responsible for.
The AT light can come on when the automatic transmission fluid is low or dirty and not functioning as expected.
There could be a leak caused by wear of the transmission pan, broken transmission seals, failure of the transmission pan gasket, etc.
The repair cost for a leak is $150 to $200, but the replacement cost is up to $200. It’s reasonable to check the transmission fluid level if there are no leaks.
Pull out the dipstick with the engine warm and the gear shift neutral, then check the graduated level on the dipstick to make sure the fluid stops.
The quality of the fluid should be checked. The fluid would be drained and replaced if it’s anything other than that.
Under the air filter assembly, the ATF fluid goes inside the Mazda 3s. The Mazda 3 is good on an average of 7.5 quarts of ATF and needs to travel over 30k miles between flushes.
Use an OBD-II Scanner
There are onboard diagnostics that connect to the car’s system and run on the issues the car faces.
If the AT light is on, the vehicle may have lost communication with the TCM. A hands-on person can fix it in less than an hour.
The battery must be removed to get to the TCM. The old one can be replaced with a new one if access is obtained.
How To Reset the AT Light on Your Mazda 3?
Resetting the AT light will not fix the problem. The AT warning light could reappear after a couple of days, trying to alert you of a possible issue.
- Switch on the ignition, not the engine.
- Press the accelerator and hold it for at least 30-40 seconds.
- Release the accelerator.
- Switch off the ignition and remove the key.
- Start the car. The AT warning light should disappear.
What To Do When the AT Light Comes On?
If the warning light comes on, it is best not to drive the car away and switch off the engine. If you can, use an OBD scanner to read any error codes that come up during the inspection.
If the AT light illuminates while you’re driving, it’s a good idea to find a safe place to pull over where you can do the same things.
If you can’t locate and fix the problem you should call recovery instead of trying to drive the car.
If you damage the automatic transmission, it will end up costing you more to fix than a tow truck.
Is It Possible to Drive a Car If the AT Light Is on?
If the AT warning light shows up on your Mazda 3 dashboard, I recommend avoiding driving the car.
A mechanic should inspect the car as soon as possible because it is a serious cause of concern. The transaxle can be damaged if you continue to drive.
Signs That the Transmission Is Failing
It is easy to act against them in the event of an AT warning because they must understand the various symptoms of a transmission failure. There are a few that are mentioned below.
The phenomenon that the car fails to accelerate properly can easily be explained.
This is caused by low levels of ATF, which causes a stutter in the pressure in the fluid that is used for the transmission to work correctly.
The signs tell you that the transmission has issues. It is easy to note because these sounds and smells are not like the car’s everyday sounds.
The dashboard Light Comes on
People who have been driving for a long time have learned to ignore the check engine light, but this signal might alert them.
This light is used to detect and alert the driver of things that pass under the radar.
Refusal to Change Gears
transmissions are at the center of the car. The shifting of gears will be affected by a bad transmission.
When an automatic transmission develops a fault, the gear mechanism doesn’t function as it should.
The tell-tale sound of the engine doesn’t match the car’s speed as it refuses to accelerate.
The most dangerous symptom of a bad transmission is wear and tear, which is caused by wear and tear.
Sometimes it’s unavoidable that drivers need to accelerate and decelerate immediately on the road.
It is detrimental to the driver’s safety and others to have a car that does not respond in a scenario like that. Whenever there is a gear change, the car will start to accelerate.
If the AT light is on, it is possible to drive the car, but it is not advisable or enjoyable. You may end up spoiling the car.
The car wouldn’t even accelerate, that’s a good reason. It’s a good idea to take the vehicle to a mechanic to get the transmission fixed so that the car and driver are not in danger.
