Me neither, I know enough to check for continuity with a meter, and follow the wiring, but when it comes to the actual operation and testing for signal etc I start to loose the plot

I've no idea, the maintenance manual isn't much help to be hones;, its transmission fault finding guide just talks about checking the the shuttle reverser pump is being driven by the torque converter, which as far as I can tell is all inside the casing, and checking the shuttle valve pressures, which I don't have the equipment to do. It makes no mention of how to check anything electrical or what moves the shuttle valve in the first place!
I would have thought that any transmission disconnect for the the handbrake would either be driven off the handbrake switch (that's missing) or load sensing which works just like applying the brakes and stalling the torque converter. Eitherway with the handbrake off one would have thought it should move. I get no sense of anything being engaged when I shift the shuttle control lever, not even a click from a relay, and there is a relay right next to the connector and microswitch for the transmission dump pedal.
I've also found the description in the manual for checking the fluid levels utterly ambiguous as it talks about the shuttle reverser, transmission and the gearbox as if they are three separate things with separate level check points. As I see it the 'transmission' comprises a single unit that houses both the automatic gearbox syle 'shuttle reverser' that sits between the engine and a manual 4 speed 'gearbox' and they all share the same oil!
