So, I've got a 2020 GLC300 with 2,000 miles on it.

Had a coupon for an oil change at a local Indy shop I wanted to use before I move out of state shortly. Technician noted I had a small trans fluid leak on the transmission cooler line and sent me a pic.

To me, it looked the color of motor oil. What say you?

Can't get into my local Benz dealer until after the New Year.

Update: So, I learned the trans fluid is Gold in color - not unlike motor oil.

Also, that the repair is relatively simple. The blue and mint green "caps" are held into the trans cooler with O rings. In the past, the entire fitting and coolant line would have to be replaced. With this redesign, the dealer simply has to replace the O rings on both of the caps.
