I really do appreciate all your help. When this all started, I was driving down the exway and it clearly was a tranmission clunking back and forth then went away, within moments the fail safe. I did use a OBD scanner. No codes. Trans shop did use their compute and come up with code 49 & code 53.
I am almost thinking the new tranny is the way to go. Although cannot afford, so I was looking for the miracle.
