2012 VW Jetta No Communication with TCM U0101 (part 1)

Vehicle is stuck in park, check engine light is on and there is no communication with the transmission control module. In this video we will be troubleshooting the CAN network using a lab scope. In Part 2 https://youtu.be/GPQ8EKtvM_g we repair this vehicle and are surprised by what we find.
