Can you send me the 3 ot 4 .jpg files via email, I am not a member of the Benz World network and it will not allow me to access. That is if it does not create and copywrite or ownership issues. Thx.

I did the write up, so here is the information I posted.

Also, here is another good MB transmission repair link:

Repairing Transmission Leak, March 2007.

Okay, so I backed my car out of the garage and noticed a puddle of fluid on the floor. Upon inspection I determined it was transmission fluid and I looked under the car and noticed fluid droplets on the transmission pan. After searching this forum I decided to replace the Electrical Connection Spacer that goes into the front of the transmission on the passenger side.

When I asked for the part at the dealer the parts guy said there was a newer version for $8.19.

I jacked up the car on the passenger side and had enough clearance to remove the electrical connector. First, I removed the connector cover using a T-27 Torx bit, then I removed the wiring harness from the clip on side of plate, then pulled down on the plate to remove it. I then moved the tab on the spacer from the 11 o'clock position to the 7 o'clock position and the electrical connector came out of the spacer. If yours is leaking expect it to be saturated with transmission fluid. Then, with a pan underneath, I untightened the bolt in the center of the spacer with a 7mm socket and pulled the old spacer out of the transmission. I lost about 3 ounces or so of fluid. The inside o-ring did not come out with the old spacer, so I reached my finger inside the hole and pulled it out.

I let the electrical connector hang down in the pan to drain any fluid that might be in the wiring harness or connector. I put some clean trans. fluid on the o-rings of the new spacer before installing it, then tightened the screw and I removed any fluid from inside the spacer before installing the elecrical connector. Remember to put the tab at the 7 o'clock position to re-install the connector and turn it clockwise until it locks in place. I wiped everything down around the connector/spacer, re-installed the cover and took the car for short test drive. Since everything looked okay, I drove the car longer before checking the transmission fluid level. I added a few ounces to get it in range.

*Note* My old spacer has red o-rings and the new one has black o-rings.

This should only take about an hour to do....depends on your skills, tools, etc.
