First to RoninSC: Yes, I know the noise will not go away. I'm an old GM mechanic and have built several gearsets myself in the 60's. They're either right or they're not, they never heal up. My dealer agreed that it will get changed, but wants some more miles on it so he can justify it. They've always taken care of all my Mercedes and see no reason why they won't this time. T
