E4OD vs. 4R100
Just wondering what the differences are between the 2 transmissions, and if they will interchange electronically? I have a 1991 F150 4x4 with E4OD, and was offered a 96 4R100. Will it work?

No, there are very different circuits in the 4R that wouldn't be able to be controlled by your E4's ECU. You'd need a stand alone controller. But hey, if someone is giving it away, take it.

The E4OD and later revision branded as the 4R100 do not interchange electronically or mechanically. The 4R100 was not offered in 1996. Yes, you can have the stronger 4R100 internal hard parts installed in a E4OD but beyond that they are mutually exclusive. Besides...the 4R100 does not have a bellhousing that will fit the earlier pushrod engines.

You can swap the solenoid bodies to make the 4R100 compatible. Or you could rewire the connector on the wiring harness to match the different 4R100 pinout. The 4r100 also has two speed sensors that the E4OD does not have. You can just leave them unplugged. The E4Od won't even know they are there.
The big problem is that there isn't a 4R100 that will bolt to an older engine.

Change the trans mount.
Lengthen the driveshaft(s)
Change the wiring harness
Change the computer - Will the '96 computer run the '91 engine? Does the '91 engine have the sensors that the '96 needs? The '96 is OBDII, the '91 is not. The '91 computer WILL NOT operate a 4R70W.
You could get a manual computer and a stand alone to run the transmission.
Not that bad, I guess.

5.4L Compatibility with 4R100
Hey Guys... Newbie Here..
I found this thread and thought you guys could help me with my current problem...
Here it is.
I had a 97 F250 with a blown 5.4L engine... Replaced it with a used 5.4L engine from a Expedition (Not sure what year). Ran fine for a couple thousand miles and then the tranny went out.... Parked it. Had a friend call yesterday and said the engine blew in his 2000 Expedition 5.4L and offered me the tranny free. I need to know if the engine that is currently in my F 250 is compatible with his transmission. Here's the Info:
Label on the valve cover reads:
7G894AB
970551645
416 02-24-97 5.4L
His Expedition 2000 5.4L (I think it's a 4R 100)
Any advice will be greatly appreciated.
Phil

None of those numbers mean anything to me. They identify the trans, but I don't know the key to reading it.
The first thing is that both have to be 4x4 or both have to be 4x2. If they are, then check the data tag in the driver's door opening. Under TR will be either a U or an E. U means 4R70W and E means E4OD/4R100. The codes must be the same. If both match, then the trans will work.

FYI, you'd probably be better off posting on this truck in the '97 - '03 F-150 (and F-250LD) forum.

You could also count the bolts on the transmission pan. The E4OD/4R100 had 20, the AOD-E/4R70W had 14.
