727 shift point question, automatic valve body

Read it a coupla times.
Does it "kickdown" if you're cruising in high and punch it ?
The early shifts kinda reminds me of the valve body
spool not positioned on the lever correctly inside the trans.
Only at lower speeds. Let’s say once above 40 mph oh it stays in drive no matter how hard you punch. (Currently 3.23 with 27" tire)

It should kick down at that point based on my foggy memory of auto’s I’ve had in the past for a decade or 2 ago…
