I did what Texas! suggested and drained the trans to the level hole and ran it for a while. 3/4 quart came out, which is odd because I filled it to spec when I changed the fluid. So I assume that it is coming from the hyd case.
When I shut off the engine I could hear the fluid pushing past the Oring seal I put on the shifter and when I pulled the hyd dipstick there was a whoosh sound and the seal stopped leaking.
I unscrewed the trans level plug and a quart drained out the hole. The hyd dipstick shows only half full since I topped it off a last month.
I looked into the fill hole on the hyd top plate that was installed when the backhoe was put on and 3-point levers removed. I could see the PTO and nothing else. Does the stock hyd top plate have a vent on it? The replacement plate does not have a vent.
Since there is no hyd pump or pipes anymore, could the churning PTO alone cause a pressure differential between the hyd case and trans case?
Is the fluid level in the hyd case much higher than the trans so the fluid leaks by gravity from the seal between the two? My thought is once the hyd level drops below the seal it will quit tranferring fluid. Is there a danger to run the hyd case too low of fluid even when the 3-point gears and levers are removed?
Sorry for all the questions at once, but I must include all pertinent details.
