Default 2001 3.0 to 2003 4.0

Alright i looked through the engine swap threads and nothing like my situation.

I found an 03 4.0 4x4 for sale with 71,000 miles

Will this be a DIRECT bolt in?

What do i need so i don't need to buy anything extra?

Engine
Transmission
Transfer case
PCM
Wiring harness (where do i cut it?)
Also do i need a new drive shaft?

Thanks so much

you'll need a tranny, entire engine/trans harness, pcm, exhaust, PATS reflash. And that's all without comparing the engine bay to ****pit big wiring connector.


Honestly...just 5.0 it. I wish I had. And I went 4.0 to 4.0.

The 4.0 will bolt right up, right? I think the 5.0 will be a lot of work to get it going. And what's the PATS reflash? Or is that the dealership thing

4.0 and 5.0 are bolt-in swaps. It's the other crap like tune and computer work that screw ya.


PATS is the security system that has the chipped key(simple terms. lol).....a new PCM is required and you've gotta match the PCM to your key. Trip to the dealership is a must.....and it'll be a tow. This is very very factual for the 3.0. The 5.0, some have done it but it's a headache.

So I can get a 5.0 out of an explorer,4x4 and that's what I don't get is the computer. Idk what to do with the wires lol. So the dealership just needs to reprogram the key pretty much? So that it will work with the new pcm

Alright so i did some research and really want to do the 5.0 swap. But i don't know anyone that can do it reasonably. I looked at the 03 today and it's nice, He said for everything needed for the 4.0 swap he would charge me 1500 and he'd swap em. But i really want a 5.0
