You can't even get a new mechanical diode for this trans.The dreaded mechanical diode.
Make sure the convert it to the other style.
Don't have them put in another new mech diode
Yes, you can. It will all fit. It won't last long at all, though. The 5.4L parts are nowhere near strong enough to last behind a 7.3L.Can I pull the guts out of a 4r100 off a 5.4 and put them all in my 7.3 4r100???
Oops! I forgot about that. E4OD internals will NOT work in a 4R100.it would follow that the tone rings or whatever the sensor feeds off of wouldn't be there in the earlier transmission.
Yep, that's true, too.PLUS, a lot of components in the E4OD were aluminum that were upgraded to steel in the later 4R100s. I wouldn't want to go backwards on reliability by putting in the weaker components.
