I just removed mine and it is not that bad at all, Mine is an 05 F250 but the procedure should be the same
My book said to put the truck in neutral, but then i couldnt pull the key out so i left it in park. It didnt seem to make a difference to me.
Remove transfer case skid plate (4 bolts)
Remove fwd and aft drive shafts
Remove tranfer case (6 bolts, use a trans jack)
remove access panel on fwd side of engine rear cover to get access to tq converter nuts
Remove tq converter nuts (6 nuts, I used starter to turn flywheel)
Remove all connectors , and starter
Install tranny jack and remove crossmember
Remove 9 bolts on bellhousing (you can get to all of them from behind the trans with a really long extension)
Move the trans straight back a few inches until it clears and lower jack.
The worst part is the Tq converter bolts. Overall not a bad job.
