What is causing these codes. I have replaced the TCM and the old one looks like it was a replacement also. The dealer tells me it will cost $2000+ to fix the car. They say I need a new torque converter but from some videos I have watched that would be wrong. My car is a 2005 Chrysler pacifica touring 3.5 I have replaced both O2 sensors with denso sensors and am still having the same MIL problem. Any suggestions?
