Today, my husband was driving my 2003 ford taurus with 89,000 miles. He was accelerating after a red light and the speedometer went to 0 and it would not go into gear. I have read online that some of the causes of this probleme could be a bad speed sensor, a bad cylinoid, a bad connector, or a bad trans. We had it towed to the shop, and he just said that he had connected it to a diagnostic machine, and no codes were pulled, so he thinks the trans needs to be rebuilt. Do all of the causes pull a bad code? He said that they were going to flush the trans. to see if it helped. I mentioned what I had read about the sensors, and he said he would check it. I have been taken advantage of by mechanics in the past. Has anyone else had this problem?
