This caused me to rapidly decelerate to approximately 40 mph, I am lucky there was not another vehicle behind me when this happened since rapid unexpected deceleration without brake lights is very dangerous. I had to drive the truck in limp mode at 45mph and approximately 4500 rpms to the nearest exit. This event illuminated the trucks check engine light and…

   The control valve body failed. There are so many, that there was a shortage of parts. Had to take it in as it went into limp mode. 34,000 miles. There were dozens of trucks, same year, waiting for the same repair. Shop says probably every truck will need it. It is a known issue.

The initial diagnosis is an issue with the "valve body". a quick search on the internet presented several other users with this…
