This was a planned drain-and-fill at 10,250 miles on the truck and the fluid. Factory-fill ATF (DW-1). Fluid color and odor were good. Very little short-tripping or city driving, but there were several trips into the mountains and on lots of Forest Service roads and mountain trails. The Widman site calculates VI at 190.
