Default Transmission slipping

Hey everyone
I have a 04 2500hd n the trans is starting to feel like it's slipping. But it's not throwing any codes in the computer... I was wondering if any one has any idea to try cause I've heard that the touque converters are not that strong on this year trucks.. I'm thinking about gettin it overhauled and built up any suggestions on who to take it to located on va nc or Maryland?? Also I'm running a 35 with 373 thinking bout goin to a 411??

Before you change the gears you might want to check 4lo.com they have gearing charts that can get you closer to your rpm range. I looked in to this a couple years ago and it seemed to me 456 was a better match for 35" tires.
About your tranny. It may be defueling instead of slipping. I just got mine back up. Have been running full tune transmission slipping mostly in the 2nd, 3rd and 4th gears. It even had a hesitation at wot. Backed the programmer off, it stopped slipping. Maybe this can buy you a little time. Hope it helps.
