You need to have the system live data scanned, that way the tech can see in real time what the computer is seeing as far as the speed of the truck, it could be something as simple as a sensor ground, to more expensive items like the main control processor. Just throwing parts on is wasting money, have it checked out by a shop of your choice, most good shops will have a scanner that can do this.
