The most common source of transmission leakage is the electrical connector on the passenger side of the trannie. I replaced mine last fall. In the past 6 weeks, I have fallen victim to the second most common cause. I was seeing a spot on the garage floor of about 3 inches (75mm) diameter per day. The cause was a torn "shift interlock boot" [Part # 140 270 13 65] located on the drivers side of the trannie. You have to drop the pan to replace it. Part was $12, pan gasket $11, and 4 qts of MB fluid $58. Labor was about an hour. Here's a pic of the old part.

This was repaired at a local shop. Sorry I cannot provide additional details regarding the process.

I am getting ready to replace this shift interlock boot. I am wondering about when the pan is dropped, what else needs to be removed to replace this part? The link above is dead. anybody have another one?

EDIT: for the help for others, i found another link that describes how to replace the shift interlock boot

I'm not sure if the http://www.benzworld.org/forums/3536159-post48.html post will be of help but here goes.

BTW, I will be purchasing part #45 today so that my Indy can do some preventative work. At this point I don't have a leak.

ok, here is the latest for my 2001 SLK320. Transmission number is 722618 0 3067288.
There is no shift interlock boot as described in the link of post #7, I just pulled the pan and verified it. That whole spring, pin, shift interlock, boot assembly is just deleted on my transmission. I'll post pictures later. So now I am curious where my leak is.
