hmm, well lets think about this.

1. If you jump in and go, it revs to 2.5k rpms and if you let off, speed drops quickly. This is because you are in first gear, and the engine braking will slow the car quickly.
2. If you just turn the engine on, and let it idle, not much is happening with the tranny. In park, the transmission shouldn't be turning. Since not much in the way of motion is occurring, the tranny fluid isn't really heating up.


This is pretty standard from what i've seen. Your tranny may have some wear on it, but as long as it shifts normally after a few minutes, I wouldn't be terribly concerned.

I would however, have the tranny fluid and filter replaced soon.
