Default Transmission remap-1996 4.0, 2+2

My tranny shifts into overdrive at 52-53 mph. I would be much happier, especially in city driving, if it would shift to od at around 40-42 mph. Is it possible to change the shift points in this unit? Thanks for any thoughts.

My, my, no opinions, huh? Very surprised as to that. Surely this subject has come up before. The high perf cars I have driven all shift earlier than 52mph to overdrive. Even not so high perf cars do this. 52 mph wastes gas in city driving.
