Have contacted an outstanding repair shop in Cypress Texas called Skeeters. They were not convinced it's a torque converter and sent me a copy of a service bulletin which suggests replacing the brake pedal position sensor which may actually be the part responsible. It discusses that there is a very particular voltage range that must be maintain, if not it can interact both with the brakes and the torque converter to cause this shudder. Also, I found that the shudder is dramatically lessened by disengaging the the TC system with the switch. I am going to replace the BPPS to see if that further helps. The BPPS is less than $30 and takes less than 5 minutes to replace.
