I was actually not even looking for this information, I was rather searching on the coolant piping diagrams to see where I could order a missing screw. I came apon the diagram of the LS430 new 6 speed transmission wand how it handles climbing and descending a hill.
Also lists how the LS430 has improved over the previous generation, comparisons to rival car makers, and better valve.
