I have gotten this code for the tcm a few times in the past whenever I would get the jeep real muddy. It would usually go away after a few days and never noticed anything unusual with my xj when I would get it. So it came back a couple of weeks ago after a weekend of wheeling. My tranny still seems to be working fine just the code doesn't want to clear this time. Where is the tcm even located so that I can check it out and make sure it is clean and that everything still looks good. Any others thoughts on this are always appreciated.
