Sunstrand 90 - 1136

[gt14rider 1,254]

Hi all , got a question.  Working on a 1972 charger 12 with a sunstrand 90 - 1136 hydro gear.   The tractor sat for 30 + years . I drained atf ,the atf was dark, but no shinny parts in the pan. New atf, 1410 filter, service all the ports , checked springs, replaced all O rings, checked valves ( forward and reverse ), springs look good, no nicks or burrs . Took a red wh filter off, so it's been a while since last service 

Question is how to get some atf up in the top of pump.  Don't want to dry start if possible. What do you guys think 🤔
