gears

[jasond]

I need some advice... I pull a 40' toybox 5'er with my 05 3500 4x4, the truck is an auto with 3. 73 gears. I'd like to change out to 4. 11 or even 4. 56 gears to make towing better. My questions are... . will I need the computer reflashed?... will I need my Edge juice/attitude reprogrammed?... . Are there any other things I need to consider? Also, does anybody know a good shop in or around Riverside, Ca that could do the swap?

The speed sensor measures wheel rpm, so you only need to reflash if you change tire size, not gears.
