Tranny woes

Hi everyone,
I recently changed the conductor plate on my 722.6 transmission because of limp mode/shifting problems. Now I got it all back together reset the TCU and put it in drive and got nothing also reverse got nothing i was expecting worst case the problem stayed the same not gotten worse. Anyway the torque converter is fine the transmission itself is fine I'm wondering if I screwed up an electrical connection or linkage or something putting it back together. Any help would be much appreciated
