Ok. 1st & foremost, before you get pi$$ed, I don't actually know if you can convert a 2x trans to a 4x trans. I'm a good mechanic on the 4R100/E4OD, but I've never done a 2x-4x conversion. But since you were given the 2x trans, you can try a little experiment. If the 2x trans is empty, & you've got a clean area to lay parts & the transmission out, start by removing the tailshaft housing. If your 4x trans is out of your truck this next part will be easy, but it can be done on the ground or on a lift with 2 people; Disconnect the 2 wiring harnesses & the rubber breather hose on the transfer case. Unbolt your transfer case from the trans(x6 13mm bolts: USE A 12pt WRENCH!!!). If you wiggle it up & down, it'll eventually slide out. If the trans is out of the truck, it's easiest. If it's in the air, it's 2nd easiest, if you're on the ground----BE CAREFUL! Your transfer case weighs about 80-90lb. 2 people will need to secure it out of the truck no matter which way you're working on the truck. Some ATF will come out of transfer case/rear of the trans. Just make sure you catch what comes out with a drain pan & discard it.
There's an adapter with intermediate gears between the transfer case & the tail of the trans. Since the bolt pattern is the same on both sides, see if the tailshaft housing off the 2x matches with the adapter on the 4x. You also need to count the teeth on both impeller shafts(splines) of both trans' & make sure they have the same amount of teeth & they're the same size. The only thing that's making me think this won't work is the tailshaft housing's bolt pattern on the 2x, if my memory serves me correct(haven't done a 2x in a LONG time), has a strange offset where the 4x4's is almost in the center.
BEFORE YOU TAKE APART ANYTHING: Give both trans' tail housings a visual inspection to see if the offsets are different. If they look close, try to follow the directions above & see if they match. If there's any type of difference, don't waste your time; it won't work. You'll save yourself a lot of aggrivation.
If it does work- drain your transfer case after installation & fill it with new ATF. You have to remove the adapter/intermediate gears from the 4x4's trans(the intermediate gears in the adapter are an assembly; nothing should fall out but a little ATF). The input in the assembly should slide onto the spline of the output shaft on the back of the trans. You'll need to replace the 2 gaskets for the adapter too. If you get them from Ford, they come 2 in a pack(both sides are the same bolt pattern)& will run you about $30-$35. Then, bolt the transfer case to the adapter; keep in mind install is reverse of removal. You still need 2 people to reinstall the transfer case, line it up, & bolt it back in.
Another thing you have to keep in mind if you make it further than the visual inspection & it turns out this all works; the adapter is also the rear mount of the 4x's transmission. You'll have to unbolt the (2) 21mm bolts on the bottom & secure the transmission by the pan with a floor jack & a piece of wood. If you can secure the trans with a jack & remove the crossmember it mounts into, it makes it so much easier to remove/install the adapter's 13mm bolts on the bottom.
Hope this all helps, man.
