Mysterious E4OD Poblem(s) - Getting Worse - Help!
Thanks guys I will be pulling the codes tomorrow. Also, I may have been misleading when I said "limp mode." What I was trying to say is that the light begins flashing and then it shifts hard, but all the gears do work fine.- peacetank

Mysterious E4OD Poblem(s) - Getting Worse - Help!
Ok so my old beater econoline van with the 7.3L IDI and the E4OD is starting to worry me. I call it a beater but I want you to realize that doesn't mean that I neglect it. It just means that I don't put any money in it other than fixing what's broke and regular preventative maintenance. So I...- peacetank

E4OD Issue - O/D Light flashing
So far - So good I disconected the batteries like you suggested, and so far... so good. I took it for a nice long test drive, and the light never came back on and shifting is back to normal, so I'm hoping that the TPS that I replaced was the problem. My speedo is still going crazy, however.- peacetank

E4OD Issue - O/D Light flashing
Don't worry - it won't be going to any tranny shop - besides, I have a spare tranny anyhow (I just hope its good and I hope I won't need it). I will try to have my dad pull the codes on Wed, which should get things narrowed down. I'm still not sure why the spedo isn't working properly after...- peacetank

I have not driven it since, but my Ford service manual says that a flashing O/D light is caused due to the following "condition:" [INDENT]"Voltage through EPC circuit is checked and compared after a time delay. An error will be noted if tolerance is exceeded during KOEO and continuous...- peacetank

E4OD Issue - O/D Light flashing
It has no tach - it's an econoline van. My latest idea is that there is a bad connection where the wiring harness plugs into the tranny. One of the terminals had a little corrosion, and the Ford book says that if one of the wires looses signal, it can result in the symptoms that it has. I'm...- peacetank

E4OD Issue - O/D Light flashing
The odometer does work - I don't know how accurate it it, but I can't help but think the speedometer might have some connection with the tranny problem. As I mentioned, the problem didn't occur until I hit highway speeds then parked it.- peacetank
