Thank you for contacting us Shawn,
Please see the answer below from our Tech Support Engineer:
"Regarding Honda Frictions and Honda Transmission Fluid. The Raybestos Powertrain Honda frictions were developed to work in the Honda transmissions just like the Honda Frictions work.
In the past before Raybestos Powertrain developed the GPX Honda Frictions there was no aftermarket solution that worked.
If you used a different fluid in a Honda transmission it would shift different.
If you used a different fiction material in a Honda transmission it would shift different.
In most cases the different shifting would cause unpleasant results.
Raybestos Powertrain was the first company to provide a friction material (GPX) that would feel just like the Honda friction material in a Honda transmission using Honda fluid.
If you were to use a different fluid in a Honda transmission with the GPX friction material, you can expect the same similar shift feel as if the transmission had Honda frictions and the same different fluid.
It appears the transmission was designed with not only the friction material in mind, it also included the transmission fluid as well."
Thank you,
