Both trucks are the same.

2001 ext cab long bed 4x4

 

Mine is a built auto

My buddys is a NV5600

 

We are wanting to swap each other but don't know how to go about Wireharness/pcm.

The Hard parts are easy and will just swap from one to another and work fine.

 

he is wanting to go like it came from the factory. no rachet shift no full manual valve body.

 

any guidance is much appreciated

It'd make things easier to just swap ECMs between the trucks. Otherwise a Smarty will be needed to flash the ECMs to the correct auto/manual tunes.

 

Honestly, if you're trucks are identical minus the auto/manual, then I'd say just trade trucks! haha

I have to agree. Why do you want to do that?  It's a lot easier swapping titles than it is swapping transmissions. 

I miss my days when I was looking on how to kill some time
