Question 2007 E450 , TCM location

[butch2000]

Ok where is the TCM located ? the speedo is not working , so I was trying to find the TCM to check the connections for green death ? or corrosion ?

Have you checked the speed sensor? It is located on top or the rear end. It should have two wires going to it. This is a cheap part to change. Pull it out and inspect it for metal filings. Clean and reinstall, does it work now? If not change it.
