John Deere 3020 transmission pump prime

ToddMattson I have a John Deere 3020 power shift and I replaced the steering pitman shaft seal. Afterwards I have lost all hydraulic pressure. The transmission pump appears to have lost prime. The screen is clean. The tractor drove into the shop, and now it has nothing. Any help would be greatly appreciated. Thanks.
EH Gauss When I had to replace the hydraulic oil cooler on my 3010 (Industrial version), I left the top connection on the cooler open and filled the cooler with hydraulic oil before making that connection and starting it up. The outlet of the cooler (bottom) is the supply to the pump. The hydraulic system came back onto line just fine after stroking everything a couple of times. If the configuration of the cooler and pump on the 3020 is similar to the 3010 in that regard, you might try that approach to assure that the pump has an adequate prime.
