Cat 615c ejector weak

Hey guy, I’ve got a 615 that doesn’t want to push a load out the bowl.
Ejection circuit is the only weak circuit.
Lift and paddle circuits are fine.
Ejection cylinders have been rebuilt, along with new hoses and it operates fine with no load.

The one thing I have noticed is it doesn’t open or close in a sequence
Sometimes floor will open halfway then ejector starts moving forward.

I believe there is a sequencing valve but haven’t looked into it yet. Anyone have any experience with these units?
