Thank you stevebfl and M.B.Doc for the guidance. I really appreciate it.
I will first try disconnecting the kickdown solenoid and report back.
I have not had an experienced M.B. transmission tech inspect the car in person. But one of the techs I spoke to on the phone asked if the spedo was working because he said that if it was not working this was a good sign that the governor had failed. The spedo is working on my car.
