You need a screwdriver and a friend. First you open your hood. The TV cable is located right below the throttle cable. It has a button on the side. Pushing in this button adjusts the cable length. Your main goal is to make the cable guitar string tight at WOT. With the engine off, disconnect the cable and press the button on the side of the TV cable, make the cable housing "longer" by backing it out of the bracket (not too far). Let the button go. Re-attatch the cable and have a friend press the gas to the floor. The cable housing should ratchet out a little, and the tension in the cable itself should be guitar string tight. Play around with the housing through the bracket length to make it shift earlier or later. Test the shift points at part throttle. Somebody else here might know where it is supposed to shift at.

Shift points is another thing that can be adjusted for best performance. I personally like to have the shift points higher while on the street because the kick down is better. Like it will kick down at 1/2 throttle and not fall into OD as early.
Though at the track it has been proven that a stock TPI runs better sifting at 4200RPMs. Though this changes with mods to the intake runners/cam/heads bla bla bla.
Its personal preference on the street and what gives you best times at the track.
