I don't know any tranny shops in Atlanta, but Rusty Cullens (of *************** fame) is in Atlanta... you could give him a call, I know he can recommend a place or two. 800-741-5252, or email rusty@***************.

Sometimes weird stuff like this happens, even at relatively low miles. My sister's '87 300D tranny failed at 220k without any warning, one day it was fine, next day it refused to move an inch, regardless of gear selector position or RPM. What was really frustrating was the fact they had just pulled the tranny within the past year and done a full re-seal, d'oh! All that work for basically nothing. We never did find out what part failed inside, and instead swapped in a Peter Schmid rebuild. The new trans has been working fine so far...
