Line pressure after shift kit

The pressure range is controlled by the spring you install. and the adjuster fine-tunes it in that range. The springs are color coded.

Cranking up the pressure , in my experience, has not harmed my 904; I tied the lever all the way back for a while and road tested it like that. Other than Part-Throttle Bang-shifts it showed me that I needed a different Throttle-pressure spring. So after I installed it, the pressure at PT was of course way too high, and the Governor fell asleep. So the first thing I had to do was adjust the governor to work with the new Line Pressure , and then fine tune the KD system, then fine tune the line-pressure again.
Along the way, I discovered that the 1-2 shift, and the 2-3 shift were not synchronized; one was occurring much sooner than the other, soooooo Off came the VB again. By the end of the summer, it was all working fairly well, so the following winter I took it apart and freshened it up, mapping all the springs and things so I could build a clone.
Well that never happened, as I sold that whole powertrain to my son, and it was gone.
and I have no idea where I put the map.
