Okay, At the 69 Mph if the truck is letting off the throttle it is because of a parameter set that way. If you have PTT or access to it, you need to go into features and parameters and change the "next highest gear" setting. This is probably set to 69 mph, so when it hits that the eecu knows what gear it is in because of the road speed and rpms. I usually put that parameter around 5 mph less than the max highest gear setting. There is also another parameter if the unit does it in the highest gear. The one labeled max vehicle speed which is a programmable parameter that either a dealer or fleet with programming capabilities has to do. Let me know if you have any questions. Thanks
