struggled with output sensor on trans after long pull. (700 and 722) Dodge techs on 2 different occassions said the 471 and 472 codes were due to the tube leading to the sensor being plugged or dirty. finally changed the sensor for 400 series codes and the problem went away. (have a dodge 4500 w/300k) trying to figure out the connection just for the sake of passing on the info to others. any input?
