ML350 2009 Bad transmission leak
I backed out of the garage and then saw a large pool of transmission fluid on the concrete. I only seems to leak when it is running. I will post a video. Does anybody have any idea on where this may be coming from?

vague. Best way is you take a video while it is leaking. Don’t be afraid to crawl on the ground.

Inside that bell housing will be a torque converter which has some 3L transmission oil inside. Your fluid looks like red ATF dex3/4??

Not sure what transmission oil was used in the last service. Transmission was serviced about a year. It was serviced at a Mercedes service center.
Your right, I'm definitely not driving it. I was lucky to notice it and not take it on a longer drive. My first thought was the drain plug for the torque converter because of the amount of oil. I rotated the converter until I could see the plug and it was fine, no signs of damage to the converter, although it isn't easy to see into the bell housing. All the oil is definitely coming from inside the bell housing.
Because of the amount of oil coming out I was hoping that it might be something simple like a loose drain plug. I can't think what have to break for there to be that much oil come out? I would assume if a seal was busted then it would be a slow drip.
