Case 2090 gets oil on the inside of the left rear tire

I have noticed that the inside of the left rear tire on my Case 2090 gets oily. Definitely transmission/hydraulic oil. Laying on my back and looking upward at the left rear side I can see what looks to be a couple factory holes in some in some little hydraulic components - either hydraulics or power shift. I think oil drips once in a while and it gets on the tire. Nothing is broken or cracked, oil must be dripping from one of those holes. I don't know if component would be a pressure relief with a center that screws out??? Using the hydraulics and power shift while planting. Can you identify where the oil is coming from? If so, how do I fix it?? Thanks.
 
The most common item to leak behind the left rear wheel is the filter pressure sending unit, it should have a wire plugged into the end of it. Most of the time the wire is not connected, this unit threads into a rather large pipe, approx 1 in diameter. There are many connections, pipes and hoses in that area, any one could be producing the drip. I have already had to remove the wheel and pressure wash that normally filthy area and run the tractor in order to find some of the more difficult to locate leaks. Rod.
