I'm not new to the forum, but I forgot my username. Anywho, I just picked up a 73-74 140h3. From what I can tell I has never been worked on. It is in really good condition, though it spent the last 3 or so years outside. I got it running, but I don't seem to be getting any hydraulic pressure from the transmission. I pulled the seat pan and covers, fan. The relief valves seem to be up at their limit. Fluid looks good. Its red so type F, I'm assuming. Level looks good. But I was getting nothing, as far as drive, or hydraulic jacks moving. (loader is on its own system) Now it seems i'm down to changing the filter. I pulled it off, but it's not oem, I can't find it, or a good cross reference. Can someone help me out with a part # for the transmission filter? Does it have to be JD or can I get something at napa?
