Best option would be rent a vehicle that could tow the donor to you location.
As you remove things, label wire connections and document what all was connected to everything and take lots of pictures of everything.
It can be done, but it is not going to be a straight swap and fire it up deal.
Novel, yes it would be a novel vehicle.

Did you say you had a E4OD in any of the earlier posts? Did the 99 have a E4OD? If not, I would think this is a show stopper. You are going to have two computers? The original one to run the tranny and the other one to run the 99 engine? How are you going to marry the sensors required to run the tranny along with the ones required to run the engine? Is there room to mount and run both systems on the engine? The best scenario here is they built the E4OD in 99, and your donor had a E4OD in it.

About the cummins swap. Did Dodge not make a tranny worth using with the cummins? Why does everyone want to keep their Ford tranny and buy an expensive adapter? Did they put the front driveshaft on the wrong side for a Ford and that's the reason?

Dodge can't build an automatic that would stand up to a 5HP brigs and straton to save their lives. Actualy the ones behind the common rail engines weren too bad but the ones behind a 12 valve are junk.
My truck has an E4OD the doner had a 4r100 same basick trans identicle electronicly. I still need to find out how the 99 trans got refrence for the VSS and tach.on our trucks and the early powerstrokes the signals came from the dash if it dose too then it should work. The thrtle pedal is basicaly a FIPLS mounted to a pedal same signal out.

I have heard, but can't verify that there are some differences between the IDI E4OD and the early PSD and 4R100's. Enough of a difference that they are difficult to interchange. If it was mine, I'd keep the E4OD computer and figure out if the TPS on the throttle gives the same signal as the FPLS and piggyback the sensor to control the transmission. Do the same thing for the tach signal. I don't think it will matter if the engine ECM does not see the transmission behind it.

ECM shouldn't care about the trans signal except for a nutral signal. I'm trying to figure out where the tach and speed signals come from on the 99 to the trans controller to see how i could integrate it. Giggity
