I have already swapped to v10 governor springs and done some other modifying there to raise my shift points. I am also maxed out on line pressure with my modified Transgo shift kit, everyone (or at least I though everyone) knows that on a 47rh maxes out at about 175psi and will also cause early low throttle shifts but super late on throttle shifts due to how the throttle pressure and kickdown pressure circuit is designed. Nothing wrong with my lockup at all, it locks and unlocks like it was designed to... but I along with many others do not like how it is designed to operate; hence why so many people add a torque converter lockup switch. If I thought I would be happy with how a vendor would program my truck to shift, then I would be going that route.

I would not say my transmission shifted like stock, it was extremely firm and at a very late high rpm shift. I didn’t build it, just had a shop do it. I do believe they changed the lever on the throttle valve to adjust the proportion. Does fluid temp effect a mechanical circuit yes, I work in hydraulics, yes I can trace a schematic, yes I understand how this works... however, I do truly Believe you are trying to re invent the wheel here. It’s been done, and proven, while you keep trying to redo it. Swallow the humble pie and get it professionally done. As I stated before that trans was in negative 30 and 110 temps. Did just fine.
