transmission on 2006 Mercedes-Benz S430

My car sound like a motor cycle when I am driving along at speed of about 40 miles. It don't want to change gear until I stop and trun off the car and start it again. This is just sometime. It only happen three times. Am I having transmission problems?

Maybe you do, but to proper diagnose your car needs to be driven by an expert mechanic. If it is that obvious maybe driving it on a short distance it can be determined what is is.
