I'm not sure exactly how to describe the issue I'm having with my '07 Fit S - Auto, but I'll try.

It seems to happen two times - when I'm at a stop sign and when I'm on the highway travelling at a constant speed. I highly suspect it happens other times, this may be the only time its noticeable.

When driving down a flat stretch of highway at a constant speed it almost feels like you hit a small bump in the road, though I could also describe it as a slight hesitation. The transmission is not shifting and it happens whether or not the AC is on (i.e. its not the compressor engaging). I've watched the tach when it happens and it does register as a slight decrease in engine speed - though it doesn't feel like the engine is skipping or anything. More like the engine is being asked to pick up additional load.

The second time I feel it is when I'm at a stop sign with the car in gear and foot on the brake, it feels like the transmission drops in and out of gear - again like a slight bump. It happens worse when the AC is on, and like on the highway, I can see the event happen on the tach.

I'm calling the shop tomorrow (I have 4K miles to go on my warranty). I tried searching and couldn't find anything here - though I imagine there are many ways to describe this issue.

Anyone have any ideas? I find its far better to go into the shop with more information. I am fearful that they will be unable to duplicate the problem or say "its the way it is" when I know this only started happening a few weeks ago. I would suspect that issues like this would be noticeable during acceleration, but its not. Right now I think its transmission related, but that's just an opinion based on limited facts.
