Hi guys,

I have a 2000 gmc sierra 5.3 4wd with around 107k. Starting around last winter, there is what seems to be a resistance or sticking when i start to move forward from a stand still. It seems like you have to give it a little more gas before it starts to move, then after a couple seconds that resistance goes away and it moves along fine. This originally occurred rarely, but now its making itself more common.

Im wondering if this has to do with transmission, transfer case, or rear end? I bought this truck from my dad and it has never had a trans or rear end flush or anything like that. Any ideas?

Thanks.
