Recently replaced my 700R4s friction plates and reinstalled the transmission.

Now however it will not go into gear and is now spraying fluid out of the vent tube, I did no shift kit and didnt touch the valve body nor did I mess with the pump. Everything under the pan is in order.. I'm sure there are a ton of possibilities but any idea on what to look at first?

Also, there seems to be no fluid getting to the lines? I'm stumped since nothing was touched aside from the clutch packs.

 

Line isnt clogged and i'm pretty sure the fluid through the vent was overfilling. However still no pressure. No one has an idea what could cause this?
