You obviously know this box is fully electrically controlled, not even a shift cable...... so EVERYTHING is controlled programmatically.
Its not like earlier auto's that were electromechanical... with the solenoids simply selecting the gear and the hydraulic system taking care of shift pressure, timing, overlap etc. The AW4DE is a classic example of a basically mechanical box with shift solenoids, the 42RLE of a hybrid mechanical box but with proportional solenoids that are used to modulate pressures.
These new boxes use proportional solenoids to control pressure, timing etc so the controlling software is VERY sophisticated including pressure feedback so the box actually can vary the shifts depending on conditions ( and also compensate for wear ). I've got hundreds of pages of documentation describing control strategies for auto operating modes... it HEAVY reading.
So the days of simply changing, valve bodies, restrictors, accumulator springs are over, its software all the way and its complex stuff that your local auto place is unlikely to have the knowledge or programming equipment to change beyond moving a shift points RPM.
And ... if you change things without understanding whats really happening then expect damaged gearboxes. IIRC MagnumPI suffered from someone "reprogramming" his 42RLE that caused him many months of major grief and at least one auto rebuild.
Also..... its not a commonly used racing box so the motivation for the aftermarket to develop mods won't be high....
That's one of the advantages of a Chev conversion.. the six speed auto ( which is a good box in the first place ) has lots of tuning options as its used in competition vehicles
So in summary ( finally )........ this will be a COMPLEX job for more than basic changes, perhaps in time some of the major auto players may do something but be VERY careful.
