Nopers. Mine didn't at least.

If your pan gasket's thinner, could be that it's torqued too much. Watch out with the torque on the tranny pan bolts. I cannot imagine the trans pan gaskets for the MB diesels varying in thickness like that no matter where you buy them, but anything's possible. For ultimate piece of mind get it from the dealer OR Fastlane. Torque on the pan bolts is something like 6ft/lb(8 N-m according to forum member Gilly) but I would confirm that. Overtightening the pan bolts is the most likely cause of leaks at the pan gasket.
