I recently instaled the Bully Dog Power Pup but only did the HP mod. I shyed away from the Tranny Smart reprogram because there was a disclaimer printed on it stating "software will not guarantee that damage will not occur to your vehicles tranny". My question is should I be worried about the doing the Smart Tranny reprogram? Am I more likely to have tranny trouble without it because of the engine tune? FYI I am using the 50hp setting on 2003 4x4 Excursion 7.3L with a 4R100 tranny. I have a 4" turbo back exhaust with full gauges. Any help would be appreciated.
You could have a pump failure with it, but with out it you will be on the clutches more. The trans files make a big difference in the way a vehicle drives, usually by increasing the line pressure and moving the shift points up. The extra line pressure engages the gears faster so they spend less time on the clutches.
