How expensive is it to fix when the oil from the transmission is going into the hydraulics?

not much.  Just takes time to split the tractor and replace the seal on the input shaft.

I'd bet $$$$ that it's the seal between the Gerotor pump(transmission) and gear pump(steering).......not a split, just a hydraulic pump teardown.

More than likely it's the seal coming out of the transmission going to the rear end for the pto. My 7 & 8000 series would leak there every so often. And yes you have to split the tractor.

The only PTO seal that could be is the one at the top?? and I've only seen one that ever transferred oil (because another dealer installed it backwards) and the oil went from the rearend (hydraulics) to the front (transmission) and that was only when he ran it down the road at high speeds from the differential ring gear splashing oil against it.....and I didn't split the tractor to replace it.

Dr Allis, your right, I'm thinking of the wrong shaft. It's been a few years since I'v had one of these tractors, I can't remember which shaft it is now. But I do remember that we always had to split the tractor to fix it.

My money is on the DR. Had it happen 2 or 3 times on my tractors and it was always the seal in the hydraulic pump. I would do the pump seal first. It is cheap and fairly easy to do. Then if  it still transfers oil, you can start looking inside.
