No crank no start after trans work HELP!

I had to pull the valve body and change the solenoids. Everything is back together. Car is close to level, but still short on fluid since I can't get it to do anything more than light up the dash. I did have U0101 lost tcm communication, and P0851 Park/Neutral switch input circuit low. So I pulled the valve body back out, realized the shift fork wasn't in correctly. Put everything back together. Plugged it back in, connection seems solid. Is it possible that I got trans fluid on the mechatronics plug, and that's enough to cause this? I HAVE NOT added fluid again in case I need to pull the pan back down again. I'm lost. This should have been such an easy job, but this has me stumped. Thanks!

Any luck? The truck won't turn over if it doesn't think it's in park or neutral. The little things test our patience and tend to be the most challenging.
