E4OD/4R100 Questions
I put a trans from a '94 F350 with a 460 motor in my '53 F100 with an EFI 434motor. I'm using a Baumann Optishift controller to control the trans. I have previously used the Baumann controller to control an E4OD behind a carbed 302.
My E4OD/4R100 from the '94 F350 has a toothed wheel on the output shaft and a speed sensor in the tail extension housing. My E4OD in the '84 has a gear driven speed sensor.
The new trans works fine in Reverse & 2nd, but doesn't shift in drive. I wired the Solenoid Connector the same as the other E4OD. I'm thinking that there is a difference in the connector wiring between an E4OD and 4R100, and my trans is actually a 4R100.

If the trans is really a 1994 it is an E4OD. The first 4R100 was in 1999.
Does the trans have two speed sensors on top of the case? That's the only visual difference between an E4OD and 4R100.
There were different wiring pinouts in different years. Yours may have a different year solenoid body installed.

After doing some research, I believe that it's a '95 to '98 E4OD. The case does have an unused spot for an input shaft speed sensor, but the only speed sensor present is in the top of the Extension Housing. This is the speed sensor for the toothed wheel on the output shaft.
I have found my problem. When I built the Solenoid Wiring Harness, I ran out of #18 AWG Red wire. I planned to use that wire for the +12 Volt lines to the Solenoids and the EPC. I put the harness aside until I got some more wire, but even though I got the wire, I never ran those two lines.
I have installed those lines into the harness, but won't get the harness back into the truck until tomorrow. I expect better results, when I do.

Mark,
I am still having a problem with the trans. It doesn't shift in drive. I traced the problem to the fact that the Baumann Controller isn't getting a speed sensor signal. The output shaft of the trans has a toothed wheel, and I used the 4R100 housing and installed a sensor.
Kevin Andrews at Baumann doesn't think that the toothed wheel on the output shaft is a Ford part, but he is not familiar with a 4R100 speed sensor.
I'll post a picture of the output shaft.

The toothed wheel on a 4R100 is the output shaft speed sensor. It does not provide vehicle speed. That signal comes from the rear axle. It is also a toothed wheel. The Ford controller expects 8000 square wave pulses per mile from the sensor in the rear axle.

The wheel is mounted on a slip collar. I got a 4R100 Extension Housing and lined the Tone Wheel up with a 4R100 Speed Sensor mounted in the top of the Extension Housing.
The problem is that I get no signal from the sensor. Is there some setup procedure for aligning the wheel & sensor? Is there a maximum gap?

I'm sure there is a maximum gap. I don't know what it is. There is no setup, this system was designed to be assembled on an assembly line with each operator just installing their part. If they are the right parts they will work.

Mark,
Kevin Andrews at Baumann says that there is a tool for setting up the Tone Wheel. There are currently two of these for sale on Ebay.
I'll try to find some instructions on the setup.

I measured the output from my output shaft speed sensor. It's only 50 mV peak. It need to be at least 600mV peak.
I made a crude measurement of the distance from the top of the Extension Housing at the sensor hole to the Tone Wheel. It measured about 3/4" longer than the sensor. I think that I need a longer sensor.
Are there different size output shaft speed sensors for a 4R100?

There are two different lengths. The DY-7M101-1230 is 18.91mm long, while the DY-7M101-1230 is 37mm long. I found this information at www.ford-parts.com. That's Ford's web portal for parts.
