Well, I never really knew how the shifting was, at I had the service done almost immediately after buying it. And I thought I was something that occurred "after warming up." But after driving 3 hours to my parents, then driving back home the next day, the rough shifting was not there. I took the 180* thermo out and put a 195* thermo in as the car was running a bit cold. It still is, but that could be due to a leaking intake manifold, maybe. That's another thing that has to be fixed, but after the recent dent to the wallet, it's going to have to wait.
Odd as it sounds, it's almost as if the trans/pcm was learing your shift patterns again. When something tranny related is changed in my PCM, it almost takes a week before things settled down.
