I need some info about swapping drivetrain parts. I'm taking a ride tomorrow to look at a parts truck (91 F150) and I'm thinking about swapping in the transmission & transfer case. My 88' Bronco has an AOD & BW1356. The F150 has an E4OD and while it should have the same BW1356 I'm not sure if it's mechanical or electric. Can anytone tell me what's involved in this swap ? From what I could find the E4OD is like 17" or 18" longer so I'm guessing I'll need to swap over the crossmember as well. Without having it here to see yet or having done it before I'm kinda in the dark. The F150 is a supercab w/a longbed so I'm pretty sure the frames aren't even close but I was hoping that they'd be the same from the front bumper to just past the door but if the E4OD crossmember sits further back I get into no-man's land.
What I'd really like to hear is that it's a fairly straightforward bolt in and that I'll be able to get away with swapping in the F150 front driveshaft & cutting down the rear shaft to fit the Bronco wheelbase. The F150 also sports a 5.8L which has some sort of spark problem but as long as I swap over the computer that one's just a bolt-in isn't it ?
This is my first venture into the land of EFI, the only major builds I've done have all been carburated, They were all "run 3 wires to the distrubitor, make sure it has fuel & it'll fire" sort of thing. I started losing interest when you needed to use your multimeter to do more than check continuity but now it seems the electronics are inescapable so I may as well jump in & the best way to learn is to do it. Oh, jeez that makes me think, does the E4OD have it's own computer or does it piggyback onto the 5.8L's ? Do I maybe *have* to swap everything (engine, tranny & Xfer) and if the BW1356 is electric how hard is it to either swap in the parts from the donor or to retro the electric to a manual ?
I know this covers a lot of ground but I need to get some idea of what this entails before I go throwing $$$ around & filling my driveway with trucks that don't run.
