I have a JD 410D 285080T serial. Was not moving in any gear tested pressure at reverser got 0psi, adjusted clutch linkage to fully release the valve on reverser now has only 50psi have not checked charge pressure yet but all other hydraulics are working good just sluggish between forward and reverse and 50psi. My main question is where do i add shims to reverser and or new spring to raise pressure and what do i need to do to make sure that i do need to add shims. Already know where and how to adjust the sluggish shift. Any info on this will be greatly appreciated! Thanks

On the shaft that connects the clutch pedal to the reverser control valve, has the little roll pin that connects the two been checked?

Do check the hydraulic pump's charge pressure. Curious to see what you have.

Turned out to be sloppy roll pin and didnt have clutch rods adjusted as well as I thought, after I got it adjusted pressure at reverser went up to 150psi in all positions. Charge pressure was 80-100psi at idle then went up to about 130psi above idle and reverser in neutral. Thanks for the help.
