1. Open the hood and look at the battery.
2. The cable adjuster is to the right and below the battery tray. It points upward. There is a plastic collar that you spin up or down to adjust. Its easily accessible.
3. Give it 2 turns then hop in the drivers seat to check the feel.
It may be easier if you have a buddy that is not an idiot or drunk help out under the hood while you check the pedal feel.
I would recommend doing this in an empty parking lot or non busy street. Sometimes it takes a few attempts to get it perfect.
If you can't adjust it enough then you may have a stretched out cable. It happens a lot on older Honda's. I've replaced a few and its not incredibly difficult or expensive to replace yourself.
actually, now that you say something, I do remember not being able to get into reverse a couple times, and putting it into first always helped for some, unknown reason. lolI figured out a trick to avoid the reverse grind a couple months ago. If you go through a couple of the forward gears before you go in reverse, no grind! Works for me, anyway. My car used to grind in reverse almost every time.
And yea, new clutch won't fix a gear grind, lol.
