I figured C-class forum is much more active and should have the same issue.
I brought my car for tranny service and was told that my transfer case is leaking. Dealer offered reseal for $800 (600+ being labor).

Has any DIYed it? There is TSB that might be related to the issue:
LI28.10-P-051935 Oil Leakage at Transfer case of Automatic Transmission 722.96X
Does anybody know where I can find it?

Thanks in advance
