YO7 you've definitely done your homework on this deal! Ok so the plan is to get WOT shift points in the ballpark with the right governor assy then work with the (2) springs. What should a person do with line psi? do you adj it first? how/when do you adj the TP (kickdown) rod
Set line presure, select governer weights/springs to the desired 2-3 shift, then adjust (usually stiffen) the 1-2 shift spring. This is the best way in my opinion. If you have a tighter converter, and do actual track testing, you might find that you will et better with different 1-2 and 2-3 shift points.
