Early 70's A'904 Torqueflite downshift

I believe that's the correct way to adjust them. Wide open throttle should give you wide open transmission pressure. I think the governor controls your max shift speed. I could be wrong though. May be @lkopaska will chime in.

Correct, and the governor valves can be ground down to raise the shift points, or a different set of valves can be ordered from A&A transmissions.
Note the difference of the bottom valves compared to the top ones.
The idea is to make the valves lighter so they don't move until later in the driveshaft speed.
I have done a few sets before.
