I have a 2010 Mazda 3 automatic, lately the AT light comes on and when it does the car gives a a little jerk. Ihad the transmission flushed . was fine for about a day and started coming on again. I took it to the city which is about 60km away and thought i could smell a burning smell. Doesnt matter what speed you are going it just randomly comes on. Any suggestions would be great.

The part about burning smell doesn't sound good. I would take it to a nearby Mazda dealership or at least call their service department for an opinion.
