    Into what gear? Can't start moving? If so, clutch.

    It doesn't go to any gear at all. We never had any problems or signs of problems and then we stopped at a fuel island and when we went to start the truck again... here's where we are.
    When you turn it to shift, it gives the same alert beeping you get if the engine is off and it's not in neutral.

    And now that you mention clutch I will say that for a long time this thing is real jerky when you're trying to be gentle backing up. Not having more experience with automatic transmissions I'd heard a lot of people say that they're just like, but I know in a standard, a clutch could cause that.

    I had to "pull start" one of the company's Volvo with IShift from MO to WA once (both full load) with the issue like that with a chain from trailer, won't start moving. Once it starts moving, it goes. After pulling transmission off there was one of the springs on the disk broken and stuck.

    Just an FYI all the fault codes these days are standardized. There are lists you can find online. May be worth downloading them for future reference if you run into issues. At least gives you an idea of where to start searching.
     
    Roger McG and Bugsy1108 Thank this.

    So now it's in the shop in Amarillo.
    On Monday, they said Wednesday.
    On Tuesday, they said Thursday.
    On Wednesday they said probably Friday... of next week.
    Time to fly home.
