Claude, A Hydro needs someone who knows proper procedure and has equip. to isolate your problem. I'm assuming you changed the internal large reliefs in the center section. This shouldn't be done, until the internal hyd. circuit is isolated from the external parts. Remember, the relief system is a pilot operated relief circuit. The pilot valves are in the F-N-R valve, and in the Foot-N-Inch valve. The internal reliefs are many times alright. Send me an email if you'd like more ideas on what you can check, but your best bet is to find a CASE-IH dealership with a mechanic who knows Hydro transmissions! You may not have a very serious problem, and I hope you don't get milked on your repair. I may be off-line several days, before I can reply.
