i think what was by passed would be the controls [foot switch, and dump lever switch] also the for wiring for controls,, i would say its impossible to bypass internal on that solenoid valve...........you need someone with knowledge to trouble shoot that solenoid valve,,,,,,,,,as i said from the start hard to believe that someone with enough knowledge to replace those parts would miss a solenoid valve that controls movement,,,,, this a shuttle shift from forward to reverse?????
