Transmission Fluid Leak - 1977 280SE (W116)

Hello, everyone -

Today my 1977 280SE (W116) abruptly developed a transmission leak. I can't imagine they are related but yesterday I had to adjust my fuel mixture and idle settings to pass Colorado emissions testing. (You can view the thread here)

Shown below is the leak in action. It is definitely coming from above where it is actually dripping off the car but I can't see exactly where it starts. My good jacks and stands are currently in storage so I can't get all the way under. It only leaks while the car is running. I checked the fluid level at the end of May when I purchased the car and it was fine. The car has never dripped any fluids before today (it does consume a little oil though). It about a 1/3 of a quart to bring the transmission fluid back up to spec.

Any insight on where to begin would be much appreciated. Thanks!

When you can, wash the area off with a strong stream of water or maybe use gunk cleaner or simple green, then you can better see where it comes from. I think there are a bunch of diff o-rings used to seal the openings on the trans like that large round disc just above the leak. first we need to figure out where the leak is. I think old cars that sit and then are started to be used again can have rubber seal problems.
