Anyone modify the tranny shift points. If so how did it work out and do you care to share your settings.

 

I did that with my Mustang when I still had it. I couldn't find anything online to use as a starting point so I just adjusted it all by feel. I kept a pen and notepad in the car and always payed attention to the shifts. If I felt a certain shift point was early or late, I'd jot it down. I broke it down into 1-2, 2-3, 3-4 and low rpm, med rpm and hi rpm. If the 2-3 shift at med rpm was late, I made a note then adjusted it when I got home. It took a long time to get to a point where I didn't have to tweak it but when I was done, I was happy with it.
