I have a 2004 3.9L automatic w/OD 13,500ml on it. with the tracion button off and OD on the car seems to lag when i floor the gas. I like to drive a bit hard from light to light to hear the flowmasters. but the rpm seem to shift late or long.
Now is it true if i disconnect the battery and then drive the car hard acouple of times it will addapt and respond the way i want it.
and if yes when i drive slow how will it affect it? will i screw up my transmission, i always keep the rpm less then the red line?
It will help a bit!

If you really want to alter the shift points in a big way, you need to pick up a chip/programmer.

It's virtually impossible to harm your tranny or engine because of the engine management software. The tranny is straght out of the GT, so you'll need to add 200+ hp before you'll start having to worry about the life of the transmission.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
