I put a 2000 5.9 and 46re in my tj. I had pcm issues so I bought another used one, which had different issues. I then picked up a MP pcm for 2WD Dakota r/t. All of the other issues are gone but I didn't realize the 2WD pcm would be a problem. So What is going to happen when I put it in 4low? Can a tuner switch it to 4wd?
