I need pcm help really technical
I posted a thread concerning 4 builds and another fried E4OD, and I have narrowed it down to a computer problem. I found on ATRAs site that solenoid 1 grounds when shifted into 1st gear then solenoid 2 grounds for 2nd and then solenoid 1 ungrounds for 3rd and so on. My pcm is grounding solenoid 1 no matter whether in park reverse neutral or drive. This is keeping 1st engaged all the time. I built this tranny and it worked great for 2 days then all of a sudden went to neutral while driving and now has no forward
gears. I unplugged the pcm connector and removed the harness to the tranny and checked each wire for a short to ground and found nothing. I checked the wire coming from the pcm and its grounded all the time. Also no forward with connector unplugged from tranny to check failsafe. So I know the tranny is fried. This is the 3rd pcm reprogrammed from Ford. Can anybody help me? Please? |
Has the PCM just been reprogrammed or was it a new piece of hardware each time?
|
The only time SS1 goes in a off state is when it gets a command for 3rd or 4th gear.
A pcm in limp can hold SS1 in a on state. Clear the faults in the pcm and retest. Lack of F/R are bigger issues. Bill |
The pcm was replaced with a reprogrammed one. The only codes are ebpv malfunction which has been plugged off and keep alive memory error but no check engine light and no overdrive light blinking. Why would ss1 be on in park or reverse or neutral, ss1 is for first gear and second and your right disconnects for 3rd and 4th.?
|
What is lack of F/R?
|
lack of F/R is lack of forward/reverse.. thats all i know that has been posted so far. haha

I don't know but trust what Bill says. He know more about these transmissions than I will ever be able to learn!
You just need the time!:-drink The start of it. Op's other tread. https://www.ford-trucks.com/forums/9...-the-dust.html Hotrd You never answered questions in the other tread (pressure testing) A quick check to see if its pumping is to remove a cooler line and start it up. This will only tell you that the tc is turning the pump. As of now you have bigger issues than a possible defective pcm. Bill |
Part of first post ...
Put it back in the truck and it worked great for about 20 miles and then my coolant guage to the engine flickered then I lost all forward gears all at once. I'm auto transmission stupid but that one comment has bothered me and might have some significance, probably not. :-huh ,,, |
Message mark kovaliski and have him show up here.

I left the other post because it was more or less ads for trans builders. If we all can't put our heads together and come up with a solution then what is this site for. Nobody has answered the previous about my coolant guage. I believe it is connected to the pcm. That's when it failed. So ok I'm going to change it up a bit. What is the difference in 97 and 99 powerstroke operating systems. How hard would it be to swap to a 4R100. It seems to me to be the same motor. Maybe not. Maybe a 6 speed swap. A 5 speed doesn't have enough towing capacity. I got to get another tranny anyways so why not right? |

I got to get another tranny anyways so why not right? if you go ZF6 you will have some issues i'm thinking, but it can and has been done. the ZF5 would be easier obviously since it's from the same era truck. that is if u don't want to fix the auto. i'm not sure whats wrong with the auto, but i'm sure Bill and Tim of all people can point u in the right direction to find the issue. |

The 4R has a few more sensors but that is about it. Not much to be gained going that route. The ZF5 would be the easiest swap but by the time you do that you could have had your E4 built by a proven builder and get the eletrical issues worked out. |
In oem form the 97-E4 is a stronger unit than the 99-4R.
This is what i see from a keyboard. Trans goes 20 miles has a failure. It was able to limp home under man1. After the man1 run it has no F and R. "The limp home added to the failure" Selection of man1 runs at max epc. This was enough to engage but slip. The unit needs to come out. Its melba T This all stemmed from 32K on the back of the truck. That was knocking the door of 40K total! If changing the pcm for the 4th time makes you happy so be it. Its your time and money. I see bad builds and troubleshooting. .02 Bill |

My wag is the area around the center support has fallen towards the center of the core. |
putting the public at risk huh?
That's why they have cdl's. Truck and trailor capacity was not exceeded. Anything else?
I believe I'm done with this site. It only takes one person to make a bad reputation. |
