Welcome to Allpar. It went from a charging system fault (battery light), so a reman PCM was tried, then to a transaxle fault with a different TIPM back to a charging system fault when the original TIPM was re-installed?
Trying a reman PCM (maybe defective out of the box?) didn't solve the problem & possibly had a different problem?
When you say that it 'wouldn't even test', do you mean that it didn't power-up?
To be on the safe side, I would want to confirm that previousdiagnosis guess. It could save a lot of time and end the rabbit holes.
Swapping modules is a bad method of repair. If it didn't fix the problem the first time, I would want to make sure that the information that I was working with is correct first before continuing.
The charging system voltage regulator is inside the PCM. Make sure that it is the actual culprit.
Google around for a 'Mopar R503444AE'.
