I am experiencing this sometimes. At start, I experience some delay in transmission shifting it appears. At the same time it feels as though the engine struggles for a few moments, but it seems as though its probably more transmisssion/shifting related. The 3.5L seems like a dog to begin with. But, It seeems to lessen the more I get underway. Should I also have the tranny flushed with some new fluid put in or is this a normal thing? JFYI, i'm at 78,000 and previous owner said she had no tranny work done yet. It just seems odd to me. My first vehicle I ever owned went 150,000 until I finally had the tranny flush done. I'm a procrastinator. LOL!
