I like this as a help (kinda the "whys" of adjustment)

and this (more rote):

Using a trans pressure gauge:
The modulating pressure for a 722.315 transmission (with transmission at operating temperature of 80 deg C. & vacuum line disconnected) in drive at 50 km/h is 2.9 bar (if the revised pressure transducer is installed 3.3 bar). Working pressure 12.5 +/- 1.0 bar (14.3 +/- 1.0 with revised transducer). Governor pressure should be 1.2 bar at 30 km/h and 2.8 at 90 km/h with either transducer. All of those values are the same for a 722.303 transmission too except the working pressure at 50 km/h with a revised transducer which is a tad higher at 14.7 +/- 1.0 bar.
(I believe this was posted by Marshall Booth and I threw it in a file.)
