Tranny Program

I also posted this in the 99 -03 7.3 forum.

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.

I'd say go for it, it's just a disclaimer to CTA.

I'd use the tranny program. It will help the tranny handle the extra hp

The computer can and should make changes that the valvebody can not. Having both, I'd vote for both.
