    2005 Volvo VNL 780
    Eaton Fuller Autoshift Transmission
    VIN # 4V4NC9TJ76N419663

    MID 130 PID 160 FMI 2 Main shaft speed erratic
    MID 130 PID 161 FMI 2 Input shaft speed erratic

    Have replaced all 3 speed sensors, harness and cleaned all connectors/connections including those at batteries and still the codes come out again.

    When downshifts from 6th to 5th or 3rd to 2nd transmission losses the gear and grinds and when from stop to start to roll out/drive transmission disengage everything and must unplug batteries to reboot until next time

    Very stressful when towards traffic lights, general traffic, loading or unloading

    Either me or mechanic cannot find reason of code popping up again

    Please help
    Thank you
