I have a long 460 tractor. The hydraulics for the 3 point gets it hydraulic fluid from the rear axle housing which gets it fluid from the transmission. Same reservoir. If you look under the tractor rear axle housing you should see a separate drain plug. If you look to see where the hydraulic fluid line connects to it is under the rear axle housing. I was having the same problem. I drained the transmission housing and refilled with new fluid, cleaned the filter, etc. The hydraulics still did not work. When I disconnected the lower hydraulic line on the pump no fluid came out. No fluid was flowing to the pump. When I drained the rear axle housing transmission fluid water, hydraulic oil and clumps of goo drained out. Rinsed it out with an approved cleaner and put new fluid in the rear axle housing. The line from the axle housing to the screen filter could be plugged up also. You might need to remove the line and check for blockage.(The line that connects underneath the rear axle housing to the screen filter). Hope this helps you with your problem.<br>
I changed hydraulic fluid,(on full mark), cleaned filter, cleaned check valve piston, installed new hydraulic pump, bled air from system, checked sensitivity control, checked draft control. Not getting any fluid to check valve piston.<br>
Hydraulic 3 point hitch still does not work.<br>
