I have an 02 w/auto I've pulled a lot of spare parts off for troubleshooting my 00 w/6spd in the future if needed. Would keeping the pcm off the 02 auto be of any use if the 00 w/6spd pcm would happen to fail?

I would keep it. It will need to be reflashed but there are a few ways to do it. They are get hard to find.

I haven't checked yet but does it matter if the pcms have different hex codes?
Yes. Plus you have an auto vs manual difference. There are series of hex codes with the same DPC code that are compatible but the auto vs manual is enough to warrant a reflash. You Can do it your self with a php hydra and the hydra software on your laptop and ford may be able to flash them. Some can and some don’t carry the software.

I have a pdf that shows all the hex codes and DPC series. What is your hex code and the donor pcm hex code? I’ll try to find the pdf to post but I have a hard copy I can look at too

so the DPC is not the same so you would need a reflash. Honestly a spare ecm is worth its weight in gold nowadays so I would keep it just in case. Ford is not the only one who can flash it etc.
