I have a dodge stratus 2003 sedan. leaving my house the other day my check engine light came on, my speedometer stopped working and my car went into limp mode. I took it to two different shops. each shop had it for over 3 hrs. and they both said I have a bad ecm board. I replaced the board twice and I still have the problem. everything on my dash works fine except the speedometer. I am lost and do not know what to do next. Does anybody know what it could be. the shops that were checking my car both said that their computers showed that the ecm and tcm were not communicating. they both said that the tcm looked fine and that all the symptoms are pointing to a bad ecm. but lke I said before I've changed out the ecm twice with no luck. any help would really be appreciated.

p.s. the one shop even took out my instrument cluster and checked it and said it was fine.
