Transfer Case Options
Was wondering if I could put a automatic 4x4 transfer case behind the 5.0 and 4R70W from the explorer. I know you can drop the AWD one into the ranger and the manual 4x4 case from the F-150 into it. I’d just like to keep it to the automatic style that goes to my selector already. It’s a 2003 Ranger FX4 Level 2. If not I guess the second question would be if I put the manual T-Case from the 150 into it and make it fit into the floor by my console would that throw any codes switching from the auto to the manual?

Welcome to the forum
"automatic" transfer case is an AWD type and has no Low Range, no 4 Low
Electric shift transfer case has a 3 position **** or buttons on the dash for 2WD, 4 High and 4 Low
You can "shift on the fly" between 2WD and 4 High, but need to stop to use 4 Low
If you want electric shift then you need the BW4406 electric usually from a 1996-2003 F-150, doesn't matter if it is from a manual or automatic trans, it will bolt to the 4R70W trans as long as it is a 4WD trans, 2wd trans has different main shaft and rear housing.
BW4406 comes in manual or electric versions
Your Ranger controls will operate the BW4406, same shift motor and wiring at transfer case
Here is where the fun begins, very hard to fit the BW4406 into a Ranger, it is much bigger than the Rangers BW1350 or 1354 transfer cases, and bigger than the AWD that came in Explorer.
Engine and trans need to be move over to passenger side about a 1/2" to get BW4406 to clear the frame rail, isn't much but still extra work.
Drive lines also need to be made to fit

Thank you!! I plan on tackling this soon once I get everything else the way I want it on the truck like suspension, joints, bearings, etc. I guess I just have two questions. Hopefully the answer doesn’t spark anymore but thank you for being patient with me lol. Either way by drive line lengths you mean the actual driveshafts right? Also what driveshafts would I need now or would I have to custom do ones?

Yes, BW4406 sits farther back so longer front shaft and shorter rear shaft
Yes, get suspension(lift?) worked out as that can change drive shaft mechanics/lengths
Found this thread for drive shaft lengths and BW4406: https://www.ranger-forums.com/8-cyli...t-case-139472/
Below are the electric shift wiring diagrams for your 2003 and 2001 F150
F150 looks the same from 1998 to 2003, so just picked 2001
F150 still used GEM module for 4WD
Ranger changed to a separate 4X4 module
But............the 4x4 module should work fine to control the BW4406's shift motor, they do exactly the same thing.
When getting the BW4406 try to get truck side connector with it, for shift motor plug in.
Because you will probably need to re-pin that side to match colors
You will have a Brown wire, for electric clutch, on Rangers it often didn't use the same connector as shift motor, you will cut it and add it to the BW4406 connector matching its Brown wire.
One other thing, 5.0l computer needs a speed signal, as does speedometer, BW4406 may or may not have speedo hook up, there are ways to use rear axle ABS sensor, but it does require $85 interface unit like the SGI-5E
