Sometimes you just have to let it sit to allow the tube oil to drain down into the pan. Do remember you have to check this with engine running in neutral (not park). At 10 quarts you must be pretty close (for a big converter) if not over. Just keep wiping and checking. When you see a true line on at least one side of the stick a couple of times in a row you will know what your level is. Make sure you run it through all the gears too to fill up all the cavities and piston areas. It is best to have the wheels just up on stands so as not to put a load on the clutches when there isn't enough fluid in there when you start.
