RE: a 2001 E320, this is really strange - I've discovered a leak where the ATF pan gasket wraps over the ATF pan. The gasket wraps over and leaves about an eighth of an inch of metal pan exposed. Mine is leaking right at that 1/8 of an inch. I'll wipe that entire 1/8" clean and dry, and within ten-minutes ATF is oozing/weeping (it seems) from under the pan gasket... I don't get it. I changed the ATF 12,000 miles ago and there haven't been any leaks at all. The gasket was bought at the dealer, the torque specification was observed at 8Nm. Two-days ago, I tightened it to 10Nm, and it is still leaking. Usually a leak like this will come from where the gasket meets the transmission, this one seems to be from underneath where the pan meets the gasket. I'm losing a lot of ATF over the course of two-weeks, about two-quarts. What gives?
