2002 Dodge Neon OBD II Codes

I looked up the codes before asking the question. I don't mean to be rude, but I'm looking for some experience or some "what else" causes. Maybe even a "why" or "this is common" with that year or at 120k, "take a look at this buddy" kind of advice.
I understand its calling out a bad tranny controller. I also understand that it could possibly be a connection or wire problem or something that someone before has run into and could offer insight on.

So let me ask this a different way.

This 02 Neon popped a code for the transmission control unit today. Has anyone seen anything that could cause this that is not a bad controller? Anyone have any advise as far as things to eliminate before buying a new expensive part?

PS Car will not shift into 3rd now both driving normally and shifting manually. This just started as soon as I posted the first question.

I hope that doesn't come out the wrong way. You answered my question. I just asked it wrong. I thought anyone would have known to look up the codes first and then go from there.

And.
Just because the PCM thinks something is bad does mean replace it. That is bad advice.

Cool. Thanks for the update. I guess it is that bad.

Thanks for your help.
