Thanks for the quick responses.

My motorhead days are long gone so this car has always been serviced by the dealer from which I purchased it. I'm pretty careful about maintaining the car because I have bonded with it. It a 2006 and only has 40,000 miles, is completely stock, and I love the sound of the V8.

The question about servicing the transmission was a good one. I checked my records and the transmission and power steering systems were serviced at 34,000 miles. I has 40K on the Odometer now.

The question about transmission slip is also a good one since my research on this problem has revealed that that is a common symptom of transmission failure. Once I get the car is moving it seems totally normal. I haven't noticed any "slipping-like" symptoms.
