    Postive table is used if the trans presure is increasing. Negative table is used if the trans pressure is decreasing.

    The intent behind it was to compensate if the pressure solenoid moved faster in one direction than the other. Just make your changes equally to both tables.

    It's also not a good idea to apply the TCC at WOT unless your trans is built for it (either by the factory or aftermarket). Not all TCC clutch linings are created equal.
