I can see a de-mandate in its future, I told the owner to wait for now, let's get this thing fixed up and then we can hopefully do it remotely here in my driveway. Or, get him down to Jerry. Truck is really running very good, other than the fuel tanks, 7+ mpg... I called the Volvo dealer and found a parts guy that actually knows the truck and the CM-870, it sounds like the crossover on the transmission. He has checked everything, pulled the valves, etc... The only thing left is that valve, it is $88 and in stock.
