This afternoon I went ahead and changed out my transmission harness plug/ connector, the how to's that are around for this are pretty good but I was still not sure going into it how to remove it so I decided to snap some pics of the process.
What the underside looked like, when I first jacked up the front end.
Pull down the wire connector (fastened with a clip) to reveal the screw that holds the shield in place.
There's a star pattern screw hidden away under that harness that I just pulled out of the way, unscrew it.
Once the bottom screw is removed, simply push the thin metal shield out of the way revealing the connector.
Better look at the connector.
Twist the plastic white tab towards the bottom as the arrow indicates. The twist motion pushes out the wire harness connector.
Once its released, pull it out the rest of the way, out of the way.
This is where the problem comes from... the oil leaking into the wires, as you can see its drenched in oil.
There is a 7mm bolt in the center of the connector where the arrow is pointed.
7mm setup to unscrew the bolt.
This will allow you to pull the connector assembly out, this is i the part you'll be replacing. Closer look at the connector you'll realize that you did not have to purchase the whole connector, rather just the two o-rings that go bad over time. The connector only cost $15 from the MB dealer, the o-rings would've been $1-$2, so not a huge savings there either. The o-rings I'm referring to are pointed out by the red arrows.
Once you pull out the connector, this is what you should end up with.
The old and the new connector.
The new connector in place, with the 7mm bolt tightened.
From then on, just work backwards. The whole process took less then 30 minutes. In my situation the transmission fluid is very dark and will be replaced here very soon.
