[Ford E4OD Automatic Transmission Shifting Issue]

My codes now are 32,73,27,13,&27 again. Doesn't make much sense.

New overdrive button is in, and things have not changed, except the codes possibly. Now it's not only throwing the previous ones, but new ones as well such as 72, 13, and 27. Beginning to think there is a short circuit somewhere, which is excellent because I'm horrible at diagnosing electrical problems.

Thank you sir!

Thank you Moses, I did indeed check the vss, and it came up as faulty. I replaced, and it did indeed help my initial over revving problem. However, I tore into the overdrive button on the gear shift selector and found it had no continuity, I removed it and therefore took the truck out of overdrive. Shifts fine from second into third and so on. But now, there's an extreme shudder somewhere in low speeds ( 40-55). Also I'm throwing new codes, 25, 32, and 76.

 

Thanks for your help earlier, your previous email led me to the vss and overdrive button! I will check all connections leading to the trans when the weather clears.

27 is the vehicle speed sensor.

 

Now that I have the codes, the engine idle is rough and high, and the transmission will not shift from second to third in overdrive.

Hey Moses, rfields223 here again. I pulled the codes and got three, 12, 13,& 27. From what info I've gathered a 12 is idle control fault, 13 is dc motor did not move, but 27 seems to be a ghost.

I have a 92 f150 flare side 4x4, with the e40d transmission. Lately, in overdrive it will not shift from second gear, and on the occasion it does, it sometimes revs as if the truck is in neutral. What could be causing this? The check engine light is on as well.
