Faunsdale, AL | I think it has to dump back to the sump to get the driver weight to drop hard enough. Ours had about 1.5" return hose connected to the trans filler of the 4020 with a pipe union.
I think I would check sump screen in bottom of transmission as well as sources of high pressure leaks. The closed center conversion plug leaking sounds likely though. I have one doing that on an old loader valve we put on a log splitter. Should pull it out and inspect. | |
