If you've got a Mercedes with an automatic transmission and you're seeing a fluid leak near the electrical plug, this is likely the fix.
It's the Mechatronic adapter plug connector seal from Meyle, a quality German brand.

This little rubber seal is a common failure point—it gets hard and leaks transmission fluid into the wiring harness.

The part number is 014 930 0002, and it replaces a bunch of OEM numbers like 203 540 00 53, 203 540 01 53, and 140 270 02 50.

It's made in Germany.

Don't ignore a trans leak; grab this seal, swap it out, and save yourself a bigger mess down the road.
