    Default Dump bed goes up but won't come down

    I've come across a strange bug. My in-cab dump bed valve won't budge after I raise the dump bed to maximum height. I can fix the problem by manually bleeding hyd fluid from one of the two bed lift cylinders. This relief of pressure in that circuit allows the operator to then lower the bed. The bed works fine as long as I don't raise it to absolute max. height.

    My "if it hurts to poke yourself in the eye, then don't poke yourself in the eye" approach of not raising the dump bed to max. height works fine, but I'm sorta curious what may be the problem here. Any ideas?

    Seems to me that has happened with mine before. Don't recall if I was on a slope but as I recall I held the switch and started moving the TC and it came down.

    Try getting the front of the truck downhill and see if that helps. Maybe go forward downhill and stop fast.
