480E LL Shuttle jerking

Mark	Case 480E LL Construction King: This tractor suffered a Belville spring failure and the whole shuttle unit was rebuilt 2 yrs ago with new clutches and the works and has been great. This spring its developed a jerky motion when idling down in gear. At idle this unit should smoothly cease movement but instead jerks and lurches to a stop. And to complicate matters it doesn't always do it. I pulled the shuttle and opened it all up again but found only a tiny fragment of a fiber seal blocking a fluid port on the in the input shaft. All else was spotlessly clean with no wear. I cleaned everything and replaced the seals and unit worked fine for a few hours but returned to its eratic behavior. What might be causing the problem?
deewight	Could it be the emergency brake trying to apply itself? Have seen some 580E's where the shaft that the rotor turns on is worn badly and causing the rotor to rub against the brake pads in an erratic manner. Jack one wheel up and put it on stands and see if that could be the case. Let me know if this is the problem as there is a simple fix for it.
Mark	Not the brake. I did check it to be sure. I think it has to be something internal with pressure or porting but I can't find it.
