a727 no third gear

hello everyone, I got a 75 dodge d100 a week ago 318\727 combo, all stock, got t running really good, topped off tans fluid that was pretty much empty, went for a drive, no third gear, unhooked kickdown linkage, still no third gear, checked governor, isn't stuck, by the way reverse work so I know the front clutch is working, both bands adjusted like how there supposed to be, and I did aircheck the it, both clutches make a nice thud, I haven't a line or governor pressure test yet, I don't have a guage atm, ill get one asap, but I did look into the 2-3 shift valve, the plug was stuck, idk if that was the problem but i took it out along with the spring and valve, cleaned everything and put back in, moves freely now, anyadvice or ideas fron anyone? Oh and by the way....I did pull the trans out and pull it apart, all clutches , steels, rubber seals for pistion and inner lips were fine, startor looks good along with the sealing rings, it has steel ring on it, but anyways thanks for any replies
