Hey Silver, I have heard/felt this same thing since I bought my auto v6 RS back in June. Thought it was just my car till I read your post.

I notice that around 35-55 mph (mostly 45 mph) and w very light gas, usually just enough to maintain the speed, it does that grinding/humming sound w a light vibration. This goes away if I decrease speed, or accelerate.

I'm going to keep reading the replies to see if this is nothing to worry about, or a defect in the auto v6 transmission... but just thought I'd let you know I'm having the same issue.
