If you will be honest I am betting you are more than satisfied with your 6 speed auto.
My 6 speed transmission were a huge improvement over the old 4 speeds and I was satisfied with them until the 10 speeds came out. I would really like to have a 10 speed transmissions now.
Of course, a lot of the need for more gears depends on how powerful the engine is and how much you are towing. Both of the 6 speed transmissions I tow with are being used at or over there rated capacity and the Cummins in the motorhome was detuned to 300hp to avoid compromising the Allison 1000.
My F150 with a 6 speed has plenty of gears when towing less than 6000lbs.
