I am joining this thread becuase while coming home from the Dragon and about 33 miles from home, I drove through a little town and noticed that my speedo wasn't working, ESP/BSP ligts were on, trans stuck in third and shifter had no effect. After stopping the trans was stuck in first!. I read two codes that indicated speed sensor. I just ordered the electrical plate that contains the speed sensor in the trans and went a head and odered other parts to do a full service and also ordered parts to fix the famous trans leak even though I never had the leak. I also ordered some blue top solonoids to install while it is apart. The conductor plate was $186 from OE Discount parts. The Chrysler Stealership wanted $398 and the MB dealer wanted about $288. IF you order online specify the MB part number as even OE Discount Parts wanted $240 for the Chysler part which comes in a MB box with a Chrysler sticker over it. I plan on doing the work this Saturday.
