I just bought a 1993 ford f150 4x4. I found some wiring under the dash that I traced to the trucks PCM. The came from a metal box with no markings on it. Si I opened it up and found Baumann on the motherboard. I looked it up and found the founders history of this and was surprised about what it was for. It has over drive so an E4OD I would guess. I know nothing about this and the previous owner was a young kid whos grandfather probably had this Baumann piece installed.
Just what does it help with the transmission. There was no booklet and I have no idea what, if any, particular model it was. I see where the inventors first build was in 1988. Any help with finding out more about this? I think I head that it is programable too? I am in the process of putting a new, stock intake back on it and fixing a lifter that wasn't pumping up. So maybe within a week I should start it up again.
Its a very cool looking truck. He had a valet program in it too. Again I had to find this out on my own. The grandpa shaved the door handles and with some trial I figured out how to use the remote to unlock and open the doors. Plus I found a handy cable under the frame that will open the door manually. Flare side that has been lifted at least 6 inches. Well done with beadlock rims and steering dampeners. Still exploring it.
So, any help or showing me possible links to look to find out more or find a booklet, or manual to see how to learn its capabilities, would be appreciated.
It's a transmission controller
"Helps" the trans is an understatement, the controller "makes" it shift
A 14 bolt AOD would not need a controller, must be a E4OD
A booklet or papers are probably available, but it will just be for installation, not much to learn except for the engineering details, and that is probably NOT in the booklet
Sorry that I don't have any pictures to show yet but I will. It is the original EFI 5.0. The transmission has overdrive so an E4OD, 20 bolts. It is a stock 302 or 5.0, which ever you prefer. I saw the word programmable while reading the Baumann page. I will provide photos soon. I assume you can help give help with the info I provided now. I would not have asked if I didn't want the help!
If it is an original OEM EFI truck with an original E4OD, the transmission should have been controlled by the engine controll computer, not an aftermarket controller.
We have someone who can confirm the way these things were controlled, and possibly shed additional light on the subject.
The only way I knew about this controller was to take the controller box apart to find who built it. When I got the truck, I started it up before I bought it and it kinda ran. So I got it into my shop the next day. I started it a few times but it would die and not start again. The previous owner had installed a valet system on it, The kid didn't know what it was, only that the key fob would unlock and open the doors. I thought maybe it had a fuel cut off portion but it didn't. The door handles are shaved off btw. Thats when I saw the aluminum box hanging down behind the pedals against the inner firewall. I took it apart to find that it was a baumann controller I replace several sensosrs and fuel pressure regulator and I did get it to start right up. I got a code reader and replaced several items/
I amTrying to get clear pictures but I don't have it on my lift yet. The new lower intake was only because the egr fitting in the intake was stripped out and held on by jb weld. So I found another lower intake with matching serial numbers. I guess I could have just had the port welded shut...but I didn't. So now its just trying to find someone that knows about the controller, how it works and if there are any programming things that canbe done if it ever needed that in the first place.
one plug in to the trans the baumann box hanging down. nothing to identify it on the outside cleaned a few lifters that wouldn[t pump up but also to change lower intake mannifold
Look like a US Shift / Baumann controller if it says Baumann. I see the heads have been painted blue - there might be more to this engine / transmission / truck build than you realize.
US Shifts / Baumann has controllers and shift kits. Did you try calling them directly?
You didn’t answer if it was still the original efi or not? Is the original PCM still installed? What is the back story on the truck? Was it running and driving when you bought it? Did you disassemble the engine, if so was it stock?
As far as I can tell the efi is stock but I haven't pulled ou the PCM to see if it is stock or not. Stock intake upper and lower. Has the normal 50 lbs of fuel pressure. But no I have not tried calling them. Now I can though with the help you and others gave. The history is vague at best.
Apparently the kid I bought it from told me his grand father bought from the original owner which came up quick because the person who bought it died I guess and it got sold early to him. So his grandfather passed on. the kid is not a truck or car guy but he is into fast motorcycles. I got a deal because he was heading off to california. Apparently it had been sitting next to the house he was renting, which was only a few houses away but I never noticed it. He didn't know if it would even start. I offered him something and we made a deal after I got it started, I heard some pretty loud lifter clatter but thought thats not too bad. So the history is gone. No paperwork in the glove compartment of any importance and he had nothing.
The heads look pretty stock. Intake runners look small and stock. Could have an aftermarket cam but hydraulic flat tappet lifters. I will check vacuum on it at idle when I get it running and see what the compression looks like. I see there are cams offered for this stock 5.0 efi system. I am not sure how much a stock efi can handle though. It might be a low end cam, more torque and smooth idle. I can try to check the cam lift at the lifter. I have a lot to do apperently.
At least I have things to check now and and maybe a phone call will helpl sort out that transmission device. So for now I will try to answer any questions or try to get pictures. I am very curious to see what it does when I can get it running and driving,
From what I am seeing now with some recearch, it looks like it was supposed to come with roller lifters orginally. If that is the case then the engine in my truck isn't stock. But why flat tappet? Makes no sense to me. At least I could replace roller lifters easily. I can't use them now on a flat tappet cam, wrong geometry. Thanks for pointing that out. The blue heads now makes sense since it was worked on. Butsuch a down grade to put flat tappets in. Maybe I can borrow a camera to look inside the cylinders to see if it has a different piston top. Its weird, I just wish I could talk to the grandpa that woned it for so long.
… So I found another lower intake with matching serial numbers.
I hope you didn’t spend a whole lot of time in that search. All of the 5.0L truck upper plenums are the same. Early plenums did not have the displacement on them but instead had “electronic fuel injection”. Later intakes did not have the PCV port in the back.

50# for a 302 is too high. It should be 30-35# and max out around 45#.
You have the valve covers off so what is cast into the head? Stock for that year should be an E7 head.
Entirely possible that someone replaced the cam and lifters.

No. Flat tappet until ‘94.

Cars started getting roller cams in the 80’s. Trucks did not. You can put a roller cam in there since the valley should already be drilled and tapped for the roller spider. My ‘89 block was roller ready.
No, '92 and '93 5.0 truck motors were roller from the factory but it wasn't the same cam as used in '94+ motors. The Crown Vic went to the 4.6 modular in '92 so leftover 5.0 longblocks(with E6 heads and a small roller cam) were used up in trucks.

I stand corrected. I thought they weren’t roller until the change to the 351 firing order.

Can you post a picture of the lifter valley with all the stuff removed.
Also look at the top outside corner of the pass side cylinder head and post up what letter or number is cast in. See yellow circle in the pic below.
It would not be unusual that the motor was replaced in a truck this old, several swaps wouldn't be out of the question.
Find the equipment decal on the drivers door pillar and post up a picture. The trans code will show what trans was original. If the truck had a manual, C6 or AOD originally then a trans controller would be necessary to swap in an E4OD since both a controller and wiring harness would be necessary.
