I rebuilt my trans now always in 2nd

To make a long story short i rebuilt my trans(200-4r)because i burt it up at the track.Every gear was foward(2nd gear) including reverse.When i tore it apart i found the fowards welded together.Well i put it all back together and now i at least have reverse but it still starts out in 2nd and stays there,doesnt attempt to upshift(manual or automaticaly)Now i did check the governer when i put it in and its free and the springs in place,i checked the foward drum for cracks and didnt see any.Also when running the tv cable does have tension on it so i dont think the valves stuck.So what could of i screwed up?Also i air checked everything when puttin it together at it all sounded good.
