TEPC valve prob needs adjusted. it changes the line pressure. I read a thread yesterday from ls1nova71 and he had the exact same thing. some quotes below:

I'm not ex exactly sure, but when it shifted, it wasn't immediate, it would kind of hesitate or slide into the next gear. The transmission shop said something needed to be adjusted and that the pan had to come off to do it. They just said to bring it in and they would fix it, and since they rebuilt it, I wasn't going to do it so I didn't really find out what it was that they adjusted.

They adjusted the EPC valve. Basically adjusted line pressure manually.
