This. Thankfully mine was covered until the extended warranty.

Check the color. If its green/yellow to red it could be a trans connector. The red fades out over time and the trans fluid turns a green/yellow color. Oil is well obviously yellow to dark brown depending on age. That would mean a rear main seal.

i was hoping it wasn't that. any idea of what that cost to repair?

Definitely rear main seal, had mine done last year, make sure you replace the plate and all new bolts too

Dealer is over $1200. Indy shop quoted me $1,000

Bummer. If mine ever goes out, I'm installing a 3K stall converter at the same time.

This is my logic. Mine has started to seep a little and i figure I'd put it off until I can get my hands on that stall. One of those "while i'm in there" mods.

now why did you guys have to go and put that in my head.

after a second look, it might be trans fluid. any common leaks in the trans?

Trans electrical connector. Check the color like I previously stated. Easy DIY and around $25 in parts.

Also could be as simple as a new oil drain plug and crush washer not being used during past oil changes

There is a recall out for this I believe. I replaced mine without knowing. Check if it has a recall/service bulletin for this issue and see if the job was done by Mercedes. I could've gotten it done for free. I only found out when my fuel senders were leaking and asked Mercedes to check on outstanding work that needed being done
