Its my first time on this forum, I'm 17 and got my first diesel. Its a 2002 f250 7.3 2 wheel drive. Any way I have a edge cs and it has 3 settings, towing, race, and extreme. When its on any of these it shifts kinda rough on 2nd and 3rd. Then when I have it on race or extreme it runs fine for a bit then it sounds kinda funny, like the motor stutters. But when its on stock none of this happens. Some one please help me and tell me if its ok for it to shift rough through 2nd and 3rd and tell me if its normal for that engine stutter? Thanks
