Blinking od light and more
I have a 93 250 with a non turbo 7.3 with an e4od. Background info this transmission was rebuilt last August and has a little over 20,000 miles on it. Last week it was hesitating to long before shifting. I changed the fipl and the speed sensor on the rear end with no luck and it seemed to shift fine until Wednesday when I looked down and od light was blinking and it started shifting hard into 2nd gear. I took it to a transmission shop, yesterday, and they adjusted the fipl again and cleaned the battery cables???? and told me it was good to go. Today it would make a roaring sound with some vibration that i could remedy by easing up of the pedal until it stopped. Then it didn't seem to make a difference how hard i pressed the pedal it would not make the noise when I tried to. On the way home the noise to be worse and it started to slip and sometime would just refuse to change gears until i took my foot completely of the pedal and waited for the rpms to fall and od light is back on and blinking. The tach and speedometer works fine. It seems to be all sorts of symptoms and problems are coming up. Whats wrong with my transmission.

I have had almost every problem with an E4OD that you can have and the list is long, check the; codes, fluids, vehicle speed sensor on the rear diff, brake lights, tach sensor, EEC switch on tran(pass side), neutral safety switch aka the MLPS(drivers side), and the fuses. Ford overloaded the tranny with info sources and made it as complicated as humanly possible. Your problem sounds like it might be the MLPS and mine was going out and was not throwing any codes, took 3 1/2 mechanics 12 hours to find the problem. good luck

the fluid is clean and looks good. I've been to 2 different shops and that's the first thing they check. I have changed the speed sensor fipl on the injector pump and the neutral safety switch on driver side today. What is a ECC switch and where is it? Nothing is working

Mine still dose the od light sometimes 7 years ago I had the trans tor down because of you verry problem trans was ok but they replaced my tourqe converter I new that was going two different shops told me that my maine trany problem was a bare wire comeing from the sensor in the rear diff wen it would groud out the speedo would bouce and kick out of cruise control the od light would start blinking and kicking in and out of gear. Ford told me the trans was shot as did a tranny shop ford wanted 3800$ and the shop wanted 2800 if there was not to much wrong I had a friend who used to work for ford he pulled it down and did the converter cost me 1400 there was nothing wrong with the trans it self we found the wirering problem after the trans was done

sometimes when it changes gears it makes a roaring noise and I can feel a vibration in the floor. A trans shop suggested i change the solenoid pack. Could this be my problem??

Pulled pan off today and found it full of metal shavings. Some of them 1/8 inch in size and paper thin. The magnet in the middle was almost the size of a small powdered doughnut with fine materials!! I'm not a transmission person but I do all my own engine work but I have always paid for someone to work on my trans. I would think that the trans is pretty much junk now right even though it's less than a year old.
