Are all egs53 TCM essentially the same and are compatible?

I have a 2006 Chrysler 300 with a ngc4 PCM from a 2009. I swapped out my original egs52 TCM for a egs53 but it's from a 2011 Charger. I'm not able to write the newer TCM. I reached out to support and was told that the egs53 never worked with the 2006 Chrysler. I was told that the software knows that and is getting confused trying to write the egs53 with the egs52 program.
