This on my 300SDL - I recently changed the fluid and filter. I've put in a new pan gasket and was very thorough in cleaning the mating surfaces of the pan before I re-installed it in the car. I've snugged the bolts down, refilled with fluid and left it for a few weeks while I was travelling. Coming back this week I see the all too familiar puddle of AFT on the passenger side - it looks like the low point is the drain plug but the right side of the pan (pass. side) is pretty wet.

I've just sprayed it with Simple Green and will hose it down later today so I can see it better. Diving under there I saw that the gap around the rubber seal had some fluid in it but not much fluid above the gasket - I'm thinking that it's the gasket that's leaking but again - it's a new one....

Any clues on how to better locate it would be welcome.

Thanks,
James
