one day my car starting shaking crazy and I thought that it could be the transmisión because the O/D light started blinking, so I got the codes to see what could be the problem and it gave me the code P0743 which has to be with the solenoid circuit and torque converter, I replaced both of them with a new transmission fluid and the problem kept going and the O/D was still blinking and turning on and off still, one day the car would not even make it on drive because it would stall right away...
