Above floor pan, driver side
2004 Coupe -- I started getting some type of oil on my driveway a couple weeks ago, thought I had an oil leak. Checked dip stick, and it actually seems to be slightly over-filled, if anything? So jacked up the car and looked up under it, saw some oil on the transmission oil pan, but wasn't dripping. What was dripping was this little rubber valve(?) located above and to the left of the trans box. Was hard to tell exactly where it was, but I know it was dripping (right on my forehead, even) and did my best to get a picture of it. Also collected some of the fluid dripping from it in a cut-in-half beer can - it seems too thin and clear to be motor oil; kind of resembles to me the pentosin power steering fluid, but to my knowledge this is nowhere near the PS line.

Does anyone know what I'm looking at? I scoured the service manual for hours but couldn't find any clues (doesn't help that it's >3000 pages...) Is there supposed to be a hose attached there? Any help is appreciated!

 

Above the transmission are two drains that are located underneath the windshield wiper cowl. This might be where the leak is coming from. Have you cleaned the drains underneath the cowl recently? It's very important because if they are clogged, water can get into the blower motor area and cause major problems. Here is a link to a post I did about cleaning them and replacing the alarm siren. If you haven't replaced the alarm or removed it, I would recommend doing that while you are in there. Drain cleaning & alarm LINK
Below is a picture of those drains I mentioned.

 

I swapped the original alarm that didnt work for a newer one about a year ago, but I never really cleaned anything in there. The a/c has been making weird noise recently, and I have previously had issues with the blower box, so that actually makes a lot of sense...

I'll have to give it a look tomorrow. Not sure why there would be oil in there, but it's certainly worth a look (and probably full of leaves)

 

Plus, if they are plugged, a heavy rain can cause that area to fill up and water will leak into the passenger side floor damaging electronics.

 

That is AC condensation, one on each side of the tranny BUT they drip water,,,not oil.
check these things the valve covers (right above the spark plugs)
the transmission electric connecter,,, both of these leak after 5 to 10 years of use. jim

 

Unfortunately didn't get a chance to look until today. Cowl drain was clear, drain under wiper motor was not. It was plugged so bad, in fact, that I didn't even realize it was supposed to be a drain 🤣

I wanted to check the two side drains and some other stuff, but not enough daylight this time of year. I'll take another look during thanksgiving break. I'll also have to look at the things amx1397 mentioned, as well
