I have a 2006 mazda 3 the problem starts with the at light coming up and goes in a second and the car its like jerking and stops for a second the speed goes down suddenly like i just hit the brakes hard . i took the car to mazda dealer but because the light doas not stay they can not tell what's going. i looked at it online and i say that a lot of people complain about the same problem the mazda have a problem with the tcm . after 3 month of driving the cars at that same condition and after i ask dozens of mechanics the light stay on for a while i hooked it to the computer and it says lost communication with the tcm. please look at this issue and make sure that mazda will fix it a problem with the transmission control monitor or the computer. *tr
