W211 E270 with a bit of a whine?

[lieutenant gruber]

My autobox ran very low on fluid last month so I had the ATF and filter changed to be on the safe side. I'm now getting a bit paranoid because I'm sure I can hear a slight whine at town speeds.

Should I be worried???

The car is on 188k but has a FSH from new.

You're probably just a bit over sensitive to a whine that was always there.
