there is no tcm/tranny support with predator's... so you can not change shift points, shift pressure, etc etc... you need to get an inTune or Trinity in order to have tcm/tranny support.... all predators are dead and gone - all were discontinued a year ago or more now...

what revision is that old predator currently on? when you power it up and it gets to the main menu, the revision number is shown at the top of the screen...
