So have about 2600 miles on my truck. Other than the faulty mode switch in the tranny all has been good. Anyone have luck with HP tuners to make changes to a "connect and cruise" package? I have read of many issues people have had with the 8L90 transmission (class action lawsuits). So far so good but I have decided to flush mine with the latest recommended Mobil 1 LV HP blue label fluid, just to be safe. Anyone know off hand which of the two trans cooler lines is in/out?
