AT Light flashes once.

:
2010 CX-9 GT AWD
I just experience an issue with my 2010 4dr Mazda3.
I was on freeway at about 65mph and my car had a hickup just like I step on brake fast.
At that moment, I saw AT light on and then off. After that, the car runs as normal again.
I want to ask what could caused that happened?

Thank you for any input.
 
How old is your battery? Sometimes a bad cell or close-to-end-of-life battery will cause electronic glitches.
