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

Mark... Went by the salvage yard this afternoon and found the Expedition that I got the 5.4 engine out of... The data label on the door says that it is an E transmission... The Expedition I'm getting the free transmission out of is also an E transmission... my F 250. 4x2 is a 97 model and the Expedition is a 2000 model ...do you think they will be compatible any modifications I will have to make?

E4OD/ 4R100 compatibility

Mark... Thanks for your help.
I went to the salvage yard today and found the Expedition that I got the replacement 5.4 liter engine out of... The data label on the door said it had an E transmission. The Expedition that I'm getting the free transmission out of is also a E transmission... My F 250 is a 97 model and the Expedition is a 2000 model... Any compatibility issues or modifications I will need to make?

What difference does it make what trans was in the truck in the junkyard? What trans is in the F-250 is what matters.

Mark... Well it seems to me that if the engine that is currently in the F 250 is the one from the junkyard that you would want the used transmission that you put in there to be compatible with that engine... Am I not understanding this correctly?

The 5.4L could have either the 4R70W, the E4OD, or the 4R100. They are NOT interchangeable.

A 4R100 will work where an E4OD used to be, but there are a few changes that need to be made. It's not that hard, but it isn't a direct swap. An E4OD will NOT work where there used to be a 4R100.

If you want to go between a 4R70W/AOD-E to or from an E4OD/4R100 you are going to need to do some fabrication, build a wiring harness, and at least replace the computer, if not design and build one yourself.
