I was crossing Rt80 in Pennsylvania at the end of June with cruise control set for 60MPH and was just at the top of a slight rise when the speedometer went from 60 to 0 a couple of times then the cruise control turned off, the digital mileage display turned off, the tow/haul light came on and the transmission dropped into third gear. I continued a short distance to a truck plaza and when I pulled off of the exit the transmission stayed in third gear. I shut the engine off and started it again and when I put it in gear it was still in third gear. Reverse worked ok but only third in forward positions. Called Ford Service and they arranged storage locally until today when we attempted to tow it to a local Ford Garage. When the tow truck arrived I had to move the rig to hook up and found that everything worked ok. Ford said it was the speed sensor on the output shaft on the transmission but could not get it to reoccur and sent me on my way with instructions to call if it happened again.
Well it did happen again this time 1200 miles laer as I exited the Kanas turnpike on Rte 35. Ford sent me to Enid OK. (Stephens Ford) and they replaced the speed sensor on Friday, the altanator on Monday, ignition coils (two at a time) on Tuesday and then determined it was the Powertrain Command Module. They had to order that from Pennsylvania. They replaced the Powertrain Control Module after it arrived by UPS at three in the afternoon on Thursday and I went with them for the 50 mile road test. The situation did not occur so I packed up and headed north. Two days and 1200 miles later I made it home with no problems. They said Ford felt it was a bad PCM that kept reading a bad speed sensor when the sensor was ok. It sure kept me on edge all the way home waiting for it to happen again. Sure was glad to get out of Enid Oklahoma after spending a week there. I will be going after Ford for some compensation for hotel rooms as it happened under bumper to bumper warranty to first time making it a recurring incident. Stevens Ford in Enid were great to deal with and went out of their way to look after us while we were there. Great to be home.
