So the Harley maintenance manual that I have says to use the same grade oil in the tranny as the engine. It also says to use Harley Davidson oil, grade 105 (for use in temperatures over 90’ F, I live in Savannah, Ga) in the engine. My question is does anyone out there do this still? What do y’all run in your engine and tranny? Thanks for the help and keep it in the wind.
