Sorry I missed the bit about the pressure at the modulator port.
(EDIT - oh crap you even wrote it in the title and I got all wrapped up in the vacuum part of your story)
10 bar?
10 bar?
Are you sure?
Modulating pressure should be between 0.65 and 3.8 bar from what I can make out.
Are you by any chance measuring working pressure?
In first gear you should be in the range of 6 bar to about 14 bar but there should be a drastic reduction by the time you slide on into second. That's meant to be in the range of 3 bar to 7 bar.
Please note I'm going from data in the ATSG 722.1 manual which I have found to be confusing / unreliable at times. I've got a copy of the original FSM in German with the transmission chapter - but I have to crank up Windows to view it...
...it will take some time - I'll be back...
