1985 Dodge Ramcharger erratic fluid level

Had trans rebuilt 1998 only about 30,000 miles on it before I pull the engine I removed the radiator and transmissiom cooler, when I put everthing back and filled the trans. The truck sat for about two to three years. I think I put about 5 qts of fluid . Know movement I added one qt wheels started to turn, while I was doing this Ii had the back wheels on stands, when the back wheel were turning I then put the truck on flat ground.I check level very low reading added more fluid went through the gears still very low level added more another qt. Still low. Now after 2-3 hours did not start engine 1in. Above full, started engine now its just half in. On dip stick. Could I have an air pocket inside cooler, line, trans. Etc. During my last letter I had erratic timing did air leak test only 7lbs per cylinder 100lbs drop to 93lbs. Truck has 21-22 vac. Still erratic
