Mazda 3 2010 hatchback AT light comes on and off
 

Hello,

So basically, my car every time I drive it suddenly gears down and the AT light comes on. After like 2 seconds, it would come off and the car is like normal. I recently did a full fluid flush and change the filter, but it did it again. My mazda 3 has 113 k miles. Does anyone had this problem? If so what should I do?
