do you mean as in puttin the shifter into 2nd or somewhat missing 2nd adn gettin it into lets say btw the 2nd and 4th gear? like misshifting it in a way is what you mean? i have a sligggggggght feeling that maybe i dont step on the clutch all the way when it grinds once in a while and put it into 2nd. i am not syaing that is the reason but i will pay more attention to it and see if that MIGHT be it which i highly doubt it tho.
What I'm trying to say is that if you are not getting the shifter into the precise gate for 2nd, you might be causing the grind. Try to use the left side rail as the guide when you go into second. This car has very narrow gates. Being imprecise may only aggravate the situation. Try holding the shifter up against the left side firmly as you pull down into 2nd.

yea i get what your saying now. while i was driving last nite i tried to pay attention to it and i noticed i got it into 2nd fine and on time and all. no problems. the rigidness or that hard feeling is normal right wehn you get it into the gears especially 2nd? i noticed when i put it into 2nd you hera like this click noise a small one not too loud. how is that? normal or a no no? but if it were to be grinding cuz of me, will that mess up the tranny gears or anythign really bad that i'll notice a diff. in performance or whatever it may be?

In any gear you go into, you should feel a slight "detent" just before it goes in that last little bit. "Woodwork", who is with Honda USA in their tech division, has indicated that a slight hesitation at this detent will make shifting smoother and be kinder to the syncros. I've gotten pretty fast at this "2 stage" shifting. With practice, this hesitation is a small fraction of a second, almost un-noticeable and does not slow you down at all.

As for damage to the tranny, have you seen this:

yea i was driving my car again around the city adn i noticed when i shift a BIT slower it is PERFECT like nothing wrong but once it grinding like shit and i realized it seemed like i let off the clutch too soon or vis versa so with a bit of hesitation it is fine. thanks for the help guys! much better than H-T! what do you mean by stage 2 shifting?

You don't have to shift slow to make this work. With practice you can put in this "hesitation" and still be lightning fast.
Here is what I mean by this "2 stage" stick movement (and this is my words and not an official definition):
When you move the stick, the first stage is to move it into the next gate and position it immediately before going into the actual gear. You can "lighten up" (the hesitation) just a tiny bit at this point before driving the stick home that last little bit (stage 2). (This, as opposed to ramming the stick in one continuous motion.)
When you shift to a gear that takes the stick laterally across the "H", you are already doing it in stages since the stick must change directions twice. It's the shifts where the stick goes straight up or down that it is too easy to "ram". Of course, it is generally only the 1 - 2 shift that is the most tricky simply because of the ratios involved and the fact that 1st gear is the one that goes by the quickest.

Also, check and see how your clutch fluid is doing. Maybe a change there is also in order. Do you put the clutch all the way to the floor when you shift and are you being very calculated about where you pull the shifter when going into second?
I think that most, if not all , my 1 -2 gear grinds have been caused by where the clutch pedal contacts my shoe. When the pedal has contacted my shoe in the arch area, this has caused the pedal to NOT be pushed totally down (because the pedal is in the arch of the shoe) which in turn has led to the gear grind.

ok guys, i have an 03 s2k and first to second will grind maybe two times a day and i mean GRIND THE UP! not a reg. grind i have heard. more like metal totally getting ed up. whats the reason for this? i know the 00 and/or the 01 had a recall on this but an 03 should have been fixed and was from waht i know. what can cause this LOUDD ass grind? thanks.
Hope you're under warranty. I had this problem and it required a rebuild ... then ultimately they replaced the transmission. My '03 did this early in it's life. Some of it is the synchros ... some of it is the way you drive. You can't speed shift 1-2 at the redline, period.

It isn't so (depending on what you call a "speed shift"). If you have the right tranny oil, a properly adjusted clutch pedal, and good technique, you can do a very quick 1 -> 2 shift repeatably.
