I felt like the trans shifted Okay at first. When I changed all the oils at 1500 miles it made a HUGE difference. I went with Valvoline across the board. So far the clutch, the brakes, the engine, trans and diff are all some form of Valvoline Synthetic. You could do the same with Royal Purple, Lucas, or Castrol, Mobil One what ever.
