I've had a strange problem pop up once in a whileon my '04 Civic Hybrid (CVT), but never when a technition is driving it (of course!).

I never feel the shifting, which is correct, except for once in a while when I have been driving steady speeds after the car warms up. Then when I slow down and speed up again (say, for a stop light or an interchange), I feel a hard shift, kind of a slamming into gear. I've been observing, and it really only happens when it's foggy or there's high humidity.

Does anyone have any input on whether this is normal or a problem? Does this happen to anyone else? What should I tell the service guys to look for? What in the world could be wrong?

Thanks!
