Default Transgo kit problem

I installed the Transgo kit in my 700R4 (SK-700 kit) and now I have no reverse and no neutral (engages in neutral). Any builders out there who can guess what I did wrong?

Check to see if you connected the manual valve.

X2 such a pain to drop the valve body just to connect it.

Looks like another tranny fluid shower to find out. I thought it was connected properly. I get forward gears in D,2,1 and neutral. Notch on the shifter in neutral feels weak.

Well I solved part of the problem. I forgot to snap the shifter cable clip in. Now I have neutral and notches in all the proper gears. I still have no reverse though. I took off the pan and everything seems to be hooked up. I still can't figure it out. Any more ideas would be appreciated Pic:

I think I found the problem. I took out the low/reverse boost valve and reinstalled it. The car now has reverse and all forward gears, but now I have no NEUTRAL again. WTF?

Phoned Transgo. That's what he asked me too. But it's all good now. Turns out it was just running in neutral as the clutches dragged slightly. Car was in the air, not on the ground. Took it off the lift and went for a boot. Trans runs 10x better that it did before. Shifts are solid, match the stall, and there's no bang caused by the broken accumulator spring I found when I took it apart.

It think I'm going to get an old 700r4 and rebuild it just so I have an idea how the thing works. Thanks to those who helped out.
