Default PCM Upgrade Question

I have a 2005 Turbo Lite w/ Auto and want to upgrade to GT HO. What model year PCM's will work without issue. I have a local junk yard with a 2004.

What's need to be done besides flashing the VIN?

As far as I know and have always heard, you have to match year and transmission. I have heard some say you can interchange years but I have also heard mixed reviews on that with some things not working when mixing years. I wouldn't want to be the guinea pig on that unless I knew I could get a refund if it didn't work.
