Transmission fluid Re-fill question

[SportsTrac2001]

I have a 2001 Sports Trac 4x2, I'm having the infamous shifting issue, I plan to replace all 6 solenoids first. Than see what happens..

Manuals calls for 10 quarts of Mercon Tranny Fluid, Can anyone one suggest the proper procedure for refilling.

Do I put all the fluid in first, than start the engine? or put half in than start it up and let it warm up?

Any suggestions would greatly appreciated...

I originally thought the problem was a dirty tranny filter, so I replaced that and when refilling, about qt 7 it started coming/spilling out the top of the Transmission, hopefully that was a overfill valve...(don't want that to happen again)

Thanks
Charlie
