MY CAR RUNS GREAT, WHEN IT RUNS. SOMETIMES THE CAR WILL NOT START. I NOTICED THE D3 LIGHT ON THE SHIFTER (AUTOMATIC) WAS BLINKING. I THINK THERE IS A SENSOR OR RELAY SOMEWHERE THAT WILL NOT ALLOW THE CAR TO START IF IT IS NOT IN PARK. CAN THIS BE ADJUSTED, DOES IT HAVE TO BE REPLACED, DOES ANYONE KNOW WHERE IT IS?
