just recently when i am traveling at freeway speeds and let off the gas completely my truck feels like it is hangin up on something. the only way i can describe the feeling is like one of the brakes was rubbing or one of the rotors had a high spot and was catching on the pad, but i checked all 4 brakes and they are perfectly fine. i also tried getting up to freeway speed and coasting in neutral. when i'm in neutral the truck coasts beautifully, but when i put it in gear again, i can feel little jerks or tugs, they are very subtle though. the truck shifts perfectly and accelerates perfectly, i dont hear any grinding or scraping and i just had my tranny fluid flushed and filled. i'm going to try changing the differential fluid, but that seems like a longshot because i just changed it about 6 months ago. i was wondering if some dented radiator fins would obstruct the flow of tranny fluid becasue i did notice a few dents when i took my fan shroud off. if you guys have any ideas any help would be much appreciated. thanks

Might check your u-joints and carrier bearing while you are at it. If you're still under warrantee you might need to have the transmission and transfer case checked out at the dealership to see that they are up to snuff.
