I did not turn ON my truck for 6 weeks, when I turn key lights come ON on dashboard but no respond at all, so I turn ON truck without problem with screwdriver on solenoid. But when truck turned ON can't find transmission ! Transmission is completely OFF, don't show on dashboard it's drive, neutral or reverse. Lights on automatic transmission is off, diagnostics don't show any warnings on dashboard. Voltage is 14.2 BUT converter throw warning is 0 output voltage and 14.2 input voltage. Is that all problem with batteries ? Why can't find transmission ? Truck is Volvo 2007 cummins , automatic eaton , I post photos on this post.
