Transmission problem
2003 Dodge Caravan 6 cyl Front Wheel Drive Automatic

I have a quick question. I was wondering if I bought a used tcm from a junk yard if it would have to be programmed to my pcm. I was told by the dealer it might have to be. I have read in forums it does not have to be. I have read that they just plug in and work. Could someone please help with my conflict.
