Thanks everyone for your help on this, especially ahanix1989.
Yes, I have the 6F35 transmission on a 2010 Milan w/only 18K miles on it.
Regarding the tail lamps, the dealer first replaced the brake switch (by the brake pedal on the floor) which did not resolve the problem, then ran a trace for a short as suggested which did not resolve the problem and finally determined that both rear LED lamp assemblies were not good.
The day after I left the dealer with shiny new tail lights (last Tuesday) I began once again having perhaps throttle body issues. I will post this in the correct section shortly. Thanks again.
