Found this site and he has a plethora of information on the Porsche 928 automatic transmission, which is 99% the same as the one in the 036 and 034.
For example:
1) A nice write-up on the B2 piston failure with some nice pics;
2) An alternative to the NLA Bergwerks 1st gear start (It's not for the faint of heart, as there no details, but perhaps he can be persuaded as the Bergwerks is NLA.
;
3) 722.x diagnostics;
4) 722.x adjustments
