727 Installed - No Movement in Gears

...and torque the valve body bolts because you could be sucking air.
Update: Well, I'm not too proud to admit when I screwed something up! This is the first thing I saw when I dropped the pan... hand-tight VB bolts! Mcodecuda guessed it.
It was pumping at least a little fluid, since the return line would drain fluid every time I removed it, so hopefully I didn't completely ruin anything while running my previous tests.

Torqued the VB bolts down, buttoned it up and added fluid - she now drives beautifully, as long as I don't want to go in reverse. That's right, no reverse. I did a few searches on what it could be, so here are some answers to common questions in this situation:
- I have 3rd gear. (and 1st and 2nd)
- Car doesn't try to move when in neutral.
- I did GLANCE at the servos while I had the pan off, the rear servo was not popped out or anything.

I probably should have looked at everything else closer while I had the pan off, I was just so excited that I found the loose VB bolts.

I suppose I will drop the pan again, and inspect the servo, making sure its not jammed or the seal torn. Luckily I have a nice clean enclosed drain pan so I am capturing and reusing my ATF. Any other suggestions? Thanks!
