No drive in any 727 trans position after Transgo install

Drove around the block - felt like it went into neutral and quickly popped back into gear couple of times - and overlap in Drive - forgot what gears.
Then when I put it in reverse to back into garage I lost all trans engagement - nothing.

It does show 1pt low - which I doubt would cause the control?

The overlap is band adjustment I assume.

I'm not blaming Transgo - I'm sure it is something I screwed up in the process of doing the kit.

Any ideas?

Thanks
