Okay, so new issue. I was driving home yesterday. As soon as I pull out of the plant, the OD light on my shifter starts flashing. Now the dang thing shifts like it has a shift kit in it. I know this is an issue with the e4od, but the question is, how long does she have left? I don't drive it hard. I mostly drive it when it's raining and I can't ride my Harley.

Could be as simple at your TPS (throttle sensor on IP)... I forget the correct acronym for it (flip,filp ??). You should pull codes to see what the problem is before signing a death certificate.

It depends on your mechanical ability. If you have a test light,a multi meter and some knowledge on how to use them, you can diagnose all of the external wiring for the e40d including testing the solenoid packs.

First things I would check would be fipl like mentioned already, almost every e40d truck that comes to me needs adjusting the fipl. Here is the test for that.


1. Wire A is reference voltage sent to the sensor from the computer ORANGE/WHITE

TEST: With the KEY ON, ENGINE OFF voltage should be approximately 5 volts.

2. Wire B is the ground path from the FIPL sensor to the computer BLACK/WHITE

TEST: With the KEY ON, ENGINE OFF voltage should be volts?? or less.

3. Wire C is the throttle opening signal sent to the computer from the FIPL sensor . TEST With the KEY ON, ENGINE OFF and the throttle at idle position, voltage should be approximately 1.2 volts. With The throttle fully open, voltage should be approximately 4.5 volts. ORANGE/WHITE (CENTER WIRE)


The sweep from 1.2 volts at idle to approximately 4.5 volts at full throttle should be smooth. A meter with a snapshot or min/max capture mode is useful to catch intermittent "opens".

If the previously described range cannot be attained, FIPL adjustment can be achieved by rotating the sensor (on its bracket) one way or the other until the voltage values are satisfactory.

Next easy thing to check would be brake lights, and your brake light switch. If you have any bulbs burnt out, including your third brake light, your trans will act up because the e40d reads into the brake light circuit to know when to unlock the torque converter.

Last easy test would be to pull codes like mentioned. You can buy an obd1 scanner for $35 on eBay, or you can do the test manually, following this diagram and counting the flashes. There are many YouTube videos on how to perform this test.

Awesome! Glad I could help, I would recommend reading the tech articles when you get a chance, the test for the fipl I copy and pasted directly from one of the articles, tons of useful info there.

Sorry to semi hijack but can some one point me to the I could hook a odb1 scanner to my truck didn't think there was a spot for that n Youtube well doesn't show it clearly n Google is useless for 93 n/a trucks. My trans some time jumps out of OD when it starts to sputter other the that no other issue

The scanner port you want should be under the hood along the fender near the hood hinge. It probably has a plastic/rubber cap on it.

In the picture below is that what ur saying the code port is has EEC stamped on it, there is also black one that has pins in it.

I don't believe that's it. It's not mounted on the firewall, but on the side. Take a close look at what I can sorta see in your picture, behind the hinge.

I'm going from memory because my truck is 3500 miles away.

In that picture, the silver box with the black plug and wires at the top center is the electronic cruise control. The black cable coming out of the right side of the box (right side in the picture) is the cable that pulls on the throtle.

The connector on the firewall in the lower left, with the bolt through it, is the TECA (Transmission Electronic Control Assembly).

The EEC-IV connector should be bolted near the hood hold open assembly, and be shaped like a "house". Most I've seen have a cover that says EEC-IV on it. Look in the space between the master cylinder and the drivers fender.

Yep. There it is right next to the ground screw. All Fords used this shape of OBD1 port. It was unique to them.
