Being new to MB ownership, I was reading about the extensive 7 speed auto transmission problems, apparently involving the valve body and eventual class actions law suits, etc. My question is what year models was this most prevalent in? Has it been "evolved" out?

That was for the r171. You have a r172 :D
Completely different engine
Issue was with M272/M271 engine

You have a M276 I believe

As long you change the oil and the filter in the gearbox at 40k miles you should b some extra magnets in the pan.
I may do that. I do not have the maintenance schedule in front of me, does it call for a transmission fluid change at 40,000?
