99Kleansi - That's pretty much my plan. In the spring or summer, the tranny will be getting a mild transgo shift kit. The help will be limited, however, as my torque converter is a 2300 rpm stall, compared to an 1800 rpm stall on the standard Grand Cherokee (non 5.9). I plan to ultimately put in an 1800 or so stall converter with a strong lockup clutch, so that it can safely be programmed to remain locked up most of the time, leading to better mpg (probably 15 or so, vs 12-13) around town. Highway wise, however, I can't do a whole heck of a lot without regearing or other major expense.
