Noob question 727 really low shift points

I shouldn't have mentioned the manual valve body, your first post makes it clear it is not, because it was shifting on its own back then, correct?

It does look like you trimmed the kickdown pretty tight, and left the adjustment on the wrong side, so to speak
You may need to trim the outer sheath to make it work

On the bright side, the throttle cable should be a breeze
