Ford Motor Company on the phone said contact service manager at Ford. I made contact with service manager before and after service. Provided a bulletin, for a 2015 Mustang, 3.7 automatic with exhaust knock. This has been reported as an exhaust problem, in the pass engine or transmission problem. When the engine was cold, no problem, but after it is warmed up noise appears at 5, 10, 15 MPH in first gear. Now at 1000 RPM at 20 MPH. It otherwise runs fine.
But the Ford Tech states cold or hot, there's no abnormal noise?
Question - does Ford have a problem with no fix to this or not having parts?
The next oil change will not be at Ford with a heavy multi grade oil, 10/30 weight, to see if that is the problem.
