I'm battling a 01 F body that I cant make shift before it hits the limiter @6500. Because the converter is so loose,(flashes to 5000 approx) I dont think I could move the shift @rpm down without confusing the pcm.
My next thought is to shift by mph. I'm wondering how best to go about that. Would you put the shift @rpm to say 3000 then play with the shift @ mph to get the shifts I wanted? What would you recommend with regard to part throttle shift tables? Any help would be greatly appreciated.


Thanks, Vinny.
