Transmission help PPPlllleeeaaassseee!!!

I need help.

I recently had to rebuild my 4r70w due to the fact that I'd lost my drive and overdrive. After the rebuild, I put everything back together to find nothing working at all.

Well after runing the motor for a couple minutes, I finially got it to catch first and nothing else.

I put the car into drive and I get first. Then, when It should normally shift, it basically kicks to neutral. As I coast back to a low speed, first gear kicks back in like it normally would.

If there is anything I have possably done wrong, PLEASE LET ME KNOW. I have checked tccoa, cougarnuts, mn12 performance, usatransdoctor, and transmissioncenter.net, and cant find a bloody thing on the subject or even anything similar.

Thanks in advance to anyone who can help me.

Ok I'll take a stab in the dark with this but heres a few things you could check, did you tourqe the bands to the proper specs, are all the springs and balls in the valve body in the right places or there at all, and I know this sounds elimentry but does it have enough fluid in it?
