I love a good non-answer! I guess the similarities or differences between the UH-60's trans and the S-92's vary depending on who's doing the talking.
The transmission on the S-92A and the H-60 series are similar like the transmission on a Lincoln Town Car is similar to the transmission on an F-150 pickup truck. They are made by the same company, and they deliver rotary engine power to the wheels (rotors). They don't look remotely the same, they aren't interchangeable and they don't do the same thing in many ways.
