What is the procedure for throttle pressure adjustment on an A-904? There is a screw with a stop on it to set the depth of the kickdown valve and its relation to the throttle cam. How is it set?

It's in the FSM, but the rough procedure is:

Wire the lever on the transmission all the way back.
Adjust the linkage so that this occurs when the carb is at WOT.
Drive and adjust until the shift points occur where you desire; I like mine high, so I don't change it much after that point.

I need the adjustment procedure for the throttle pressure screw that is mounted on the valve body of the transmission. The illustration shows a tool that acts as a spacer.

Ah, I didn't read ya right the first time. The manual I have for a 727 indicates tool C-3763; I assume it's the same for a 904 (can't find that manual right now). C-3763 does act as a spacer, and the relevant dimension is .625" between the kickdown valve and throttle lever cam. If I find my other manual, I'll letcha know.
