problem
ok this only refers to year 2000 owners, did you guys read about the bulletin about gear grinding, shifting to second gear at high rpm? Well, that shit happened to me and I'm pretty disappointed. I went to a Honda dealer and no warranty was available for my car since my car is at about 38K miles already. Anyone got any suggestions as to what can be done about this?

I am going to copy and paste this post I made:
Short story all 00-05s will have intermittant grinds due to syncro/trans design. The only aid is frequently changing the fluid, and or finding one fluid that does not make your shifter notchy.
If Honda MTF does not hold up many use GM syncromesh, and Redline.
There has been long debate about the longevity and problems of the 00-03 trans on this car. The biggest complaint is the 2nd gear grinds, people losing 5-6 gear, and reverse not working. The reverse issue is unrelated to this this info.
I found this info hunting around, it makes 100% sense, and also explains why the car responds so well to "oil-change-Like" interval trans fluid changes, every 3-5K. Also why the GM Syncromesh trans fluid works well.
According to many owners and technical people inside Honda the S2000 00-03 S2000 tranmission has had it's share of problems.
One of the main issues has been gear grinds, and loss of use of 2nd 5th and 6th gear.
Most people who have driven manual transmission tend to skip gears from lets say 4th to 6th. This would be fine on almost all manual transmission, but not in the s2000s case.
3 4 5 6 shifter mechanism on the s2000 are not on the input shaft (mainshaft), but on the output (countershaft). The countershaft is alway locked to the wheels and does not slow with the engine.
And in wherever the shifters are, the mainshaft will not slow to zero when the clutch is disengaged and the shfter in neutral. The countershaft is driven by the wheels. All gears remain in mesh at all times (but uncoupled from one shaft or the other).

__________________________________________________ _____________________________________________
This tranny is designed differently than most trannies. Two things were done in the design to "ensure an exhilarating and quick shifting performance that meets the drivers spirited operation".
1) Normal manual transmissions have a gear reduction prior to transmitting the power to the gear selection, thus reducing the rotational speed of the gears and shafts and synchros. The S2000 transmission has the gear reduction after the gear selection. Thus the gears and shafts and synchros have a higher rotational speed. So skipping gears will be harder on the synchros of this transmission than most.
2) The S2000 transmission was designed to keep the number of number of synchro cones to a minimum. "It is impossible to ensure gear-shift exhilaration only by increasing the synchromizer capacity through the use of a multi-cone, because the shift knob load is not reduced to a satisfactory level".
The engineering of this transmission put a higher emphasis on exhilarating feel and quick performance rather than making it bulletproof.
Quotes are from SAE (Society of Automotive Engineers) Technical Notes "Development of a new six-speed manual transmission", by K. Kitajima, Engineering Development Department 4, Honda R&D.

A TSB is NOT a recall. It's a notation to all dealerships that this problem exists and how to address it. It a Bulletin to the dealership and should NOT be confused with a recall.
Recalls are USALLY related to a safety item and you would get a mailing to your house regarding the information.
I agree with Dezoris (did I just say that out loud?
) change the tranny fluid and see if that improves your feel.

If you are miffed about it as Pete said the dealers don't have to do anything and certainly won't namely for a manual transmission grind.
If changing fluids does not help, please do the following.
Knowing that the grinds are caused by design issues, may help in writing a letter to Honda custome service.
Yes writting, do not call them as they will do nothing.
Make sure you take it to a dealer first to get it documented.
Prepare all the documentation for the letter stating exactly what you would like Honda to do.
This is the only way.
I have had to do this with other parts on Hondas and it takes months, sometimes also writing to the BBS, and Honda to get a resolution.
It even says that in your warranty statement from Honda.
Do it if you are not happy, be prepared to wait however.
