Thanks for the replies. I dumped the fluid and changed the filter. Refilled with the Case IH ultra fluid. Dropped the plate with the powershift solenoid and checked the orings on the oil tubes. We had trouble with these in the past on a 684. Removed/inspected the fluid regulator spool at the MCV. Removed/inspected the relief valve at the MCV. I also tried it with the remote lever in neutral. None of this has really changed it. The steering wheel and lines going to the steering valve still buzz. The lines going to the steering cylinder don't buzz. It's better with the wheel in a neutral position, but as soon as you turn the wheel and fluid starts going to the steering cylinder the condition gets worse and lines going across the top of the transmission start to buzz. It gets worse with rpm. The book shows a relief valve at the steering valve (book calls it a hand pump). I am wondering about this relief. Doesn't look easy to get to. One more clue. The brakes are real spongy. Any other ideas?
