After repairing 4 questionable conductors in the trans harness near the fuel filter, I still had the code. Finished up doing the rest of the plowing I needed to do, I got everything thawed off and dried out, and went back at it. When I bought the truck 5 years ago, I knew it had set at different times for extended periods, based on its mileage. A 99 doesn't have 68,000 miles on it without setting a while. Apparently, when the previous owner let it set, it was in an area where mice or squirrels or woodchucks could get under it and chew. I found another section of harness near the steering column that had 2 broken conductors, and one more that broke when I pulled on it. Soldered those all up, checked all the harness I could uncover, and I got 1,2,D and OD now. I can only imagine how much this would have cost if I had taken it to a garage! Good times in super duty land again.
I have a 2003 Ranger with auto trans. After you drive over 45 for a few miles, the o/d off light will begin to flash. It will shift hard from 1st to 2nd until you shut the engine off. When you restart the engine, the light will stay off until you drive over 45 again. then it all starts over again. Can anyone help?
