I would check the fuses for the TCM first. Here is a guide to help and fuse locations in the images below and I have included a guide to help check the fuses as well.

The U0101 code indicates a lost communication with the Transmission Control Module (TCM).

Please check fuse # 73 and # 37 in the fuse panel under the hood. Check out the images (below). Please let us know what happens.

The transmission module is on the right rear of the transmission valve body, and I have seen them have problems. Here is how to change it out. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
