SD-good question re the transmission, but remember, the S92 transmission layout is the same as the UH-60. As I may have mentioned, backfitting drive components was part of the 92 strategy ( as in, thats why the 92 has 4 instead of 5 main blades for instance-a number of us did not prevail in that discussion ), thus the 92 box, other than the shaft tilt, is backfittable and has the advantage of standing the primary servos up vertically ( or almost ) thus getting rid of all the heavy iron carrying control loads from the swashplate to the horizontal primary servos on the UH-60. The 92 main box cannot handle all the sea level power of the 901, but flat rating it for hot/high was in the plan for the 901 for Apache and Hawk anyway, or at last I think it was (?). However this all works out, the AH-64 and UH-60 pilots are going to be smiling.
SD-your point re the FARA/FLRAA speed/range differences to these two machines, not to mention the CH-47 as well, presents a thorny question in senior Army Aviation circles, one might expect.
