Re: Why little to no confirmed info on 2012 6sp auto?
Not so for me.
So, I have the updated 5 speed transmission on my 5.7L and just took it out for a test to confirm your theories. At steady speed (60 km/hr), there was no change in RPM shifting between D to 5 to D. I tried it a few times and never was there a change in RPM.
So, for my vehicle, D and 5 are the same gear and only indicates a switch from auto to manual.
