Hello all. I own a 2019 classic with the 3 liter eco-diesel. About a week ago my truck came to a stop with it unable to go back into park. It has a communication problem between the ECM and the TCM. Has anyone had this problem, and if so what did you find. My truck has 124,000 kms on it, or for those state side, around 70,000 miles. The code is U0101. Any help would be appreciated
