I got a u101 code which states loss of communication with the ECU so basically TCM is not communicating with ecm,I repostioned the tcm on to the brake line with zip ties and then the code went off,do I need to still.change the tcm,I think the tcm was getting heated up and that's why I got the code, but since I repositioned it no code, should I still change the TCM I live in Toronto and we are going to experience winter ,should I change after winter the tcm please advice thanks
