727 behind my 67-440..

I have adjusted the kickdown linkage everyway I can and the tranny still shifts 1-2-3 way to fast for my liking.. Usually into third gear before I get through the intersection.. I have 294 rear end gears so you would think it would stay in 1st and 2nd a little longer... Shifts way to early at WOT also ( no tach so I can't say exactly)

What do I do next?? Valve body work?? New governor?? Any help....
