You did not say but is your truck a 4X4?
If so and if a 2 wheel drive filter was put in the E4OD this will also cause the "Neutraling".

 

ria2005, That list is not what I wanted to hear, but you have proven that you are someone to listen to. LOL Yes, the VSS and the MLPS are direct ford replacements from the local dealership. All the issues I am having now, were all issues I was having before I had it rebuilt, including the neutraling. That is just one issue I did not mention in the first post. It does that when I am driving at roughly 25 -30 mph and if I slow down by say 5 - 10 mph and when I go to accelerate back up I have to raise the rpm's back up to get it it catch back in. When it does catch, it catches rather hard. Out of your list of possibilities I believe that the first thing I am going to look at is wiring. After that, what would you recommend that I go after next should I not find anything there? I feel FAIRLY certain (or hopeful) that it is in the wiring because when this started, it started as an intermittent problem and as time went on it got worse and worse and I personally have never seen a computer work on and off before it goes out completely. I'm hoping your not going tell me you have, then that would give me more hope it is something "simple".

 

From what you said in post #17 it does sound like bad bearings in the rear end (gap getting to wide to the tone ring).
Other than the plug for the VSS I dough that you have bad wiring.
If not bearing then I would look for loose components on the PC board of the PSOM.

But as ria2005 said above it could also be the speed control module or the RABS module also. Just unplug them both and see what happens.

You still did not say if it is a 4X4 or not.

 

Thanks for chiming in Bill, I know this subject is another one of your specialties.

The RABS module is located behind the glove box, it has been a common cause of some of your issues.

Good point about possibly having the wrong trans. filter.

 

The filter could have also fell down and that would cause it also.
A faulty MLPS could make the PCM Computer think the selector in in "N" or "P" and the PCM would then drop the oil pressure very low. The E4OD would stay in gear but you would get the "Neutraling" feeling.

 

So I have yet to find an issue in the wiring, but still not giving up on that. This is an F350 quad cab, long bed dually. There is so much wire in this truck I could wire a house with it. I have not had the time to go through it all yet, so one question on this, does anyone know of any certain area that is possibly a weak link (so to speak) in this circuit? Second question is the RABS module which I have not ruled out at this point. Is there a way to test one to see if that is bad??? As for the filter, I agree that it is very possible that it could cause an issue, but I myself am certain that is not the problem because of this. When this started it was just out of the blue. The first thing I did was change the filter myself, and when I did the old filter was still in place and the new one matched the old one exactly. It was intermittent until the hard shifting shattered the OD planetary. I took it in to get rebuilt and when it came out, it acted exactly the same. So it was pulled and gone through a second time, and this time I knew the builder personally and he is a top notch builder. He is very slow, but very meticulous. Through all of this it went through 4 filters and nothing in the performance changed. After all of this is when I started changing the TPS, MLPS, and the VSS.

 

The week point in the wiring for the E4OD is where the wiring goes into the removable plug on the passenger side of the transmission. You can not see that it is bad because of the outer shell of the plug.
But I do not think this is your problem because if all of the wires to this plug opened from the exhaust heat the transmission would go into limp mode and you would have 2nd and 3rd gear but you would not get the "Neutraling" feeling. It would have full oil pressure. That is what the shield is for to keep the heat off of the plug. Note that this shield is left off sometimes when the transmissions are worked on.
