Default U0101 Code loss communication with TCM

Hi guys/gals, I have a 2007 Dodge Charger sxt with the 3.5L. Recently I have gotten a U0101 code which is putting my car into a limp mode due to loss of communication with the TCM. This only happens when it gets cold outside. This has happened the last 2 years. Last year around the same time it happened and I replaced the TCM from one in a junk yard. Had it reprogrammed to my car and it’s worked great the rest of the winter until this winter. Any advice out there on what I can do to try to fix this issue? I just find it weird that a TCM I just replaced is already shot. Thanks
