The 4r70w bolts to your transmission crossmember just like if it was a V8 explorer

You can likely re use some of your front driveshaft, however it will not work with the 4406 output flange so it will need modified

The PCM will need to be programmed for the PATS key and PATS module, or heck program it to forget PATS all together.

I keep forgetting after 2000 Rangers had no hubs, those comments are for the 98-99 crowd

I am not sure of the 1354 E shift motor will bolt onto a 4406E shift best way to find out is to look up both part numbers see if they are compatible

Your PCM better be the same year as your engine, there are wiring changes sometimes mid year. It can be a real headache trying to piece together a conversion because the wires do move, change colors and location from year to year (96 different from 97.5, 98 went digital signals wiring changed again, 99-01 went returnless fuel) There are lots of mid year changes. As long as your PCM is from similar year you should be able to make it work
I just looked, they are not the same transfer case motor.

OKAY nice work
Now that does not mean they wont bolt up, the part numbers change because they use different wiring pigtails while the motor itself maybe exactly the same
Best way to tell is have both parts side by side
Next time I see a 4406 e shift (I see them in the yards) I will have a look see

Yeah, idk what i'm gonna do now. Sounds like a lot of work to use the 4406.

4406 e shift can be some work but its really not that bad, Wiring in the motorolla 4x4 control module is rather easy, I have all the wiring info. There are not many wires and all of them are available at the gem module behind your radio. The moto box works with the 4406 shift motor and your factory dash switch
I use this same module to delete control trac awd from earlier explorers and retain the e shift t case

The question I do not know the answer to is will the 4406 r shift clear a ranger fuel tank or is a smaller tank needed? In a 4 door explorer we must use a tank from a sport to make room
With the manual shift case none of this is an issue
But you do have to cut a hole in the floor and add a boot

I will probably just have to go with the 1354 for now

Update: I picked up a 4406 electric shift transfer case out of a 1999 F-150. I think I can use the stock ranger transfer case motor, wiring, and switch

Update: Truck runs and drives. Idles poorly. It has a 4406E transfer case in it and it appears to shift into four high, however it does not shift into four low. Can't here the transfer case motor move, no light on the dash. Any insight

Awesome you have a 5.0 Ranger!!

To get the truck to shift to 4x4 low range you must be stopped and in Neutral

Why does it run poorly? What do you mean?

It does not work even if you are stopped and in neutral. The motor doesn't seem like its being commanded to switch. The 4low light doesn't come on either. And it idles poorly. After it is warm it will idle from like 500-600 RPM and sputter and want to die

I'm using the Ranger motor and harness for transfer case. 4high works but not 4low

Did the 4low work on your old transfer case?

Does the check engine light work? (are there any codes)
How did the V8 donor run before the swap?

Check all fuses

Can you try removing the shift motor from the new 4406e t case.
Try shifting it into LOW and see if the motor moves.

With the truck in N see if you can shift the t case into low range manually (pliers or vise grips)

Put the truck in N and see if it will start? If the truck does not start in N then you need to adjust the NSS on the side of the trans

I am pretty sure the GEM module in a 2000 Ranger is what controls the 4wd switching.
We may need to compare some wiring charts here from 2000 ranger to 2000 explorer, the Gem module may not know you are in N thus stopping the low range shift....
It's quite possible your Gem module is not happy with the new transmission/conversion, lets start with the basics. Fuses, relays and testing at the t case itself

Is the check engine light on? Do you have any codes aside from the low range codes?
If not codes I would start by checking spark plugs and wires. The 5.0L eats cheap or old plug wires
Next would be looking at the conversion itself, and running some drive cycles, then pulling codes. Do you have the ability to monitor live data?

Any intake leaks? Any missing vacuum lines? What is fuel rail pressure?

It has no other codes. Isn't running lean or rich. Plugs and wires are new, Motorcraft. I was thinking it was a GEM issue, but I have talked to guys that have done this swap and they all say it is plug and play

okay so no codes yet anyways
fuel pressure test

test transfer case and motor

found these looks like 2000 Ranger does have a 4x4 control module that works with the Gem module?

You might have some wiring to do to get low range to shift
Just starting to look into this

You can see all the fuses and parts of the 2000 Ranger 4x4 system in these two diagrams

I verified it was not a mechanical issue with the transfer case. I pulled the motor off and put it in 4low with pliers. And activating the motor off the transfer case still would not engage 4low

there is a shift control module I had one in my hand a few days ago but it is basically relays. If you remove the gem it is right behind the gem... in the direction of the front of the truck. It is what "clicks" when you move the switch.

I'd work on the rough running motor then worry about the 4wd.

Congrats on getting yours running at all!

Not shifting into low range is a conversion issue, I found at least one other person on the internet with a similar conversion that cannot get low range.
The system is not happy about shifting into low for some reason, we can figure out why by sorting out the wiring differences between the ranger t case and the 4406. The 5.0L never had any sort of shift on the fly 4wd, or inputs from the t case, speed sensor or brake circuits as the AWD was purely mechanical and full time.

It is likely a signal on one wire that needs to be fed to make the Gem or 4x4 control module happy, before it will command the low range shift.

First I would find out why its running poorly??

firing order correct?
Fuel PSI good?
scan for codes?

Do you have a link to this discussion so I can read through it? I think that the poor idle may be due to running open cats

Which part... bad idle or no 4wheel low?

Cats are not causing bad idle even if empty. The upstream O sensors are all you really "need" and they are before the cats. 5.0's do not idle bad unless there is something really wrong like a bigger than normal vacuum leak, or electrical malfunction.

I'd start looking for obvious stupid things being you evidently are sharper than average about doing things and figuring things out. Get it in the dark and spray some water on the motor while it is running, look for blue spark traces. Disconnect the power brake line and put your thumb over it. If it is loud you might not be able to hear the vacuum leak.

If you took the intake off while putting the motor in maybe you got a piece of crap under it or screwed one of the gaskets up.

Has to be something simple.
