2006 Pt Cruiser pcm help!

Hi guys, I recently acquired a 06 pt and right off the bat I knew the battery light wasn't going to be a dead battery nor alternator. Needless to say, I found over a year old paperwork from a shop saying the pcm was bad. I tried my luck with a duralast preprogrammed pcm and wouldn't even test so I sent it back and installed the original. After that, I bought a dorman tipm and that didn't fix the errors which have changed from a battery light to p0700 and p0882. Just to rule out the tipm completely I installed a junkyard tipm. Same result. Now back to pcm's. I reached out to Myckee and have yet to get a response back. Unfortunately, I dont have time to wait. My question....where else can I go to get a pcm that is reputable? Thank you in advance....Tim

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 previous diagnosis 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'.

I'm sorry. I typo'd. Try 'Mopar R5034440AE'.

A P0882 can either be a TCM or a TIPM issue.
Check for fault codes in the TIPM.
These are not OBDII codes and may need a more capable scan tool to read.

It appears to be charging OK. There was a TSB #18-007-07 to flash the PCM for an erroneous P063A-generator voltage sense circuit.
