I'm in the metro Atlanta area. My car just turned 150k, so I guess it gets a badge at this point, and also it's time to do another transmission fluid change.

Short of going to the dealer or to a specialty Mercedes mechanic, both who will have fairly high prices, where's a good place to go for transmission fluid changes?

Bottom line, my transmission shifts fine now, I just want to keep it that way. I'm sure if I go to an AAMCO, they'll find some problems I didn't have before I went in, so I want to avoid them.

Thanks.
