tranny wont shift

[i heart square bodys]

okay so here's the deal ! once again I'm having issues, this truck is hell ! i just did a 700r4 swap into my truck. i put a B&M shift kit in it, corvette servo, a deeper pan, lock-up controls and a secondary transmission oil cooler. I filled it up the fluid and put it in reverse and got no response from the tranny at all! same with all of the other gears. i have verified that the pump is working as the cooler lines have fluid in them. just wondering if anyone could shine some light on what is going on here ! my guess was that the filter isn't sealing properly (or is cracked) and there is fluid movement but not enough to make the truck move (like drinking through a straw with a crack in it). just wanted to hear any advice before having to pull the pan off again. thanks !
