Sometimes you hear of a freely traveled road or bridge suddenly becoming toll access only. The promise is that once they raise enough money for a certain project, the toll will go away. I have yet to see that promise fulfilled.

But to my surprise, I could have held my breath with this new feature with Ford, as the automaker relocated it. Beginning at the start of production for the 2010 model year on Ford trucks with the 6.2L engine, the Transmission Control Module/Mechatronic unit was removed from the top of the valve body and is now combined with the Engine Control Module in the newly revised Powertrain Control Module. This change then carried on to 2011 model cars and trucks equipped with 3.7, 5.0 and 6.2 L engines. However, 4.6 and 5.4L vehicles still have an internal TCM.
