Have Mercedes Questions? Ask a Mechanic for Answers ASAP
You have to replace the conductor plate on the valve body. You have to drop the pan, then loosen the 10 bolts on the valve body and it will drop down (electrical plug housing removed). Then you can replace the conductor plate on top of the valve body where the "pig tail" pins are. Here is a link to one for sale on ebay if interested, if not, at least it is a good picture. http://www.ebay.com/itm/New-Transmission-Conductor-Plate-Connector-Filter-Gasket-KIT-for-Mercedes-Benz-/301575561790?hash=item46374de23e:g:R-YAAOSwv0tVFOm-&vxp=mtr
