A904 no shift into 2nd or 3rd

Hey guys,
I have a 74 (I think) A904 that I had out of the car and decided to pull it apart to check clutches and bands.
I replaced the front and rear clutch packs carefully and in order, rebuilt the front pump with new gears and added a 2200 converter.
I used a TCI trans kit/shift kit and did the VB myself also and added a 5.0 front band lever and new front band. I used a blocker Rod in the accumulator also
I’ve done this in the past with good results, this time something has happened.
After start up and fluid check warmed up (full) I always run them through the gears and reverse and check again... it only seems to have 1st and R...
I drove it down the road and back and no shifting.
I decided to recheck my front band adjustment and (horrible to do in the car with exhaust!) it seem like it’s right - turn snug then back off 2 full turns -
I thought sure it was something I did in the VB so I swapped it with my known good (Cheeta Shift Kit) from my 70 Challengers 727 with the same results.
I’m waiting on a new deep pan and a reusable Mopar gasket.
I’m not sure I understand how to do a pressure check with a gauge, I just haven’t found anything showing a detailed process. I have a factory service manual for a 69 Charger that may have it but since we moved I have no idea where my manuals are... probably at the bottom of the hell I call a storage unit.
I really hate not having a shop anymore!
The fact that it goes into drive and reverse well really gives me hope it’s an annoying but fairly easy fix without pulling the transmission out.
I have a new reverse servo that I now wish I would have installed while the trans was out. I literally ran out of time waiting on parts. I’m not opposed to pulling the tail shaft off the trans (I guess that’s the only way to service a A904 rear servo. Couldn’t move the rear band apply lever far enough to get it out of the way fully to get it out, it seemed fine so I left it.
This is my first A904, possibly my last.
Everything else has a 727.

I searched around but have not been able to find symptoms like I am experiencing.
BTW - when I swapped the VB there was quite a bit of band material in the bottom of the pan, no metal but a lump of band material. (Hopefully not clutches...)
I know some is kind of normal for new band/clutches, this seemed like more than I was expecting to see.
