Low Hydraulic Pressure

Don I have been having a problem of low hyd. pressure
on my DB 990 selectomatic. I have removed the pump , disassembled, and inspected completely.
I replaced all "O" rings, and reassembled. Again
I have only 500 psi at idle and 950 at full throttle. Could it be the relief valve, or a worn
out pump[ looked good, with slight furrowing in
gear O.D. wear area]. What are your thoughts??

Thanks , Don

Don
added 990 to subject line

the hyd system

Don Thanks for your reply, Robert

I am taking the pressure reading off the
remote cyl port.

Don

robert was this a sudden problem or did it happen gradualy, What kind of fluid do you have in the
transmission.
