Transmission worms up and quit working
You need to get those worms out of your transmission before you try and figure out what is wrong.
Like many owners of that vintage Accord, my '03’s transmission failed. There was a special recall deal. You may want to look into it, but 16 years ago is a long time. We did our best to warn the CarTalk public. More here if interested.
Is the fluid at the right level and does it have a good color?
