I am swapping my valve body soon on my 03.5 sedan and I will need to reflash the transmission control unit. I was wondering if anyone knew a way to do this without having to get the dealership involved. I talked to some of the well know trans. shops around town here and they dont have the diagnostic tool to do it either. which doesnt make sense to me, but i am in Anchorage Alaska, so i dont know..
I also havent seen any previous posts on this and was wondering if you guys that did the valve body upgrades had to do the same?

Thanks
