This m9000 had a hydraulic leak from the left side vent on transmission. It was foamy and after repairing the suction leak no more fluid with foam/air. Lately, the machine is in constant use moving two bales of hay down the roads to our pastures. The machine doesn't leak fluid till I am coming down the sloped road to drop off a couple of bales. Facing downhill, fluid leaks from transmission vent. The fluid is not aerated/bubbles. If I move to level ground it stops leaking. It will only leak after driving. I can operate the implement and front loader with no issues. The tractor functions normally. I insured the proper fluid level, all the vents are clear. Any thoughts on what may cause this? Other forums ran out of suggestions.
