I have a 2004 Dodge Ram 1500 with a 4.7L engine. The MIL came on this morning. I scanned it and pulled a P0700, said it could be a short in the TCM or a bad TCM. The truck still runs and shifts just fine. I called the dealership and they priced a PCM for $695. I turned the light off for now, until I heard from you guys. I appreciate any feedback.

 

You can do a search here or google for that P0700 as there are a lot of threads on it.

IF it is your PCM, you can get one here for about $250
