Funky 2-3 shift. Can you help diagnose?

This is kinda "tranny-technical", but maybe someone has experience with this.

I may have to go back into the 722.3 tranny.
It started last year when I pulled the tranny down to replace the clicking worn-out reverse plates, and just couldn't resist popping new K-1 plates in while it was on the bench. Wish I had left the K-1 alone, the old plates were pretty good.
The B-1 band looked brand new, and I left it alone.

What it does is: the 2-3 shift (first shift after take-off in 2nd) kinda has a double bump. It's not a flare, but sorta the opposite. It seems to drag down for a half-second or so, then shifts to 3rd. Kinda like the K-1 and B-1 are not in sync; one engages before the other releases, and drags it down; then the other releases and all is good.

All other aspects of the tranny are perfect, and the modulator pressure is right on.
So, I am thinking I need to check the K-1 and B-1 for proper clearances?
Maybe I got the K-1 big conical thrust plate in backwards?
