the 614 probelm i believe is my real problem i gone down the tree list and i am at a point where its askin me about LRTP validation and it shows that ecm doesnt support LRTP i guess my question would be i am probably looking AT A TCM software problem or an ecm software problem right?
had allison road guy come over and he said code 614 is almost always a bad tcm or tcm needs calibration in our case it was a bad ecm so now the bus runs and drives fine but the speedo dont work uggggg i see out put from trans but no show speed on the cummins data stream
c2 trans codes
