Thanks for the info, Jeanne!

So far I haven't noticed any grinding sound, just a shaky vibe when I start to move from a full stop. No hesitation/lurching/jerking (thank heavens!). I'll try to keep a more sensitive ear out for any grinding noise.

I'm going to take it into my Honda dealership soon as I can. I depend on my car (and it's my only car) for a lot, as do most people, I imagine, so being a full day without it is tough. I can only hope my dealership provides loaners. Otherwise I may have to take a day off work.

My car has only 25,000 miles on it, so I assume this is a problem of age and not miles driven?
