I posted this on the V6 board originally, but someone suggested posting it here instead...which makes perfect sense

Ok, I searched for this pretty extensively, but found nothing similar. This may not be anything to worry about, but if anyone has any input I would appreciate it.

For the most part, my transmission shifts just fine...nice and firm, moderately quick shifts. Occasionally, though, when I am running out second at about 2/3 throttle, it will jump in and out of third, like it wants to shift to third but then decides it wants to downshift back to second. It is not slipping, just shifting back and forth. Like I said, it is only occasional, and only at around 2/3 throttle. If I put it to the floor at this point, it winds out second a little more, then shifts firm into third and is fine.

Is this just a throttle position issue and I need to live with it (in other words, avoid 2/3 throttle from 2-3?)

Any help would be cool, even if it is "don't worry about it."
