hesitation with transmission!!!!!!

What's up TahoeLovers!!!!! I recently notice a little bit of power loss when i accelerated from a complete stop and I wasn't driving aggressively either. When I accelerated, it felt pretty powerless and then the power picked up. This is the first time this has happened. Can it be a symptom that I might need to flush my transmission? Or is it something more serious, meaning that there is the possibility of internal damage?Well, if anyone knows, hit me up... thanks

It happened to me too. What i did was too change vaccuum hoses and other GMC yukon XL 2500 Parts. Also check your ignition coils, it may be misfiring
