I bought it certified in a honda dealer, I guess the transmission oil is OK, but i will still check it. thanks for the reminning
Don't Assume... It's a cheap and easy thing to do, get honda's MTF fluid (2 quarts) and change the fluiid. While your at it, get some good gear oil too (GL-5 rating)

That almost makes sense, except it doesn't make any sense at all. If you are shifting at redline, it drops about 3000 RPMs on every shift.
Not true. Try shifting at redline 2-3, 3-4, 4-5, 5-6 . Each gear gets higher an higher.

Edit- Each gear the RPM change decreases.

Did you notice the "race stripped" part on the description of my car? I pretty much never shift it except at redline, because it's not a daily driver.

Your explanation is bogus, IMO.

There is some reason why getting into 2 is the hardest gear in this box, but the gear ratio between 1 and 2 is not it.

In my experience, the next hardest shift to make is going into 2 in the other direction, from 3.

From: 17 ft below sea level.
Default

First gear ratio = 1:3.133
Sec gear ratio = 1:2.045
3rd gear ratio = 1:1.481
Both for AP1 and AP2

When shifting 1-2 in a split second (ie, without any speed loss at all = impossible) the difference is 3125 rpm.
The 2-3 shift has a 2483 rpm difference.
A super fast 3-2 shift below 6517 rpm will have a difference of the same 2483 revs, only now the revs rise

I never miss a shift unless I call out of work first.

I can care less if you car is race stripped. And yes I did read that before I posted and thought "wow, I would think a track guy would know better to say something stupid like that?"

So when you are at 5000rpms in 5th and shift to 6th your car drops to 2000 rpms? Obviously Honda would not have geared the car that way.

Go take your car to redline in 4th and 5th and show me a video of it falling to 6000rpms.

Now I do not know what exactly makes the 1-2, 2-3 shift the most notchiest but many well-respected members including Xviper pointed to the very fact I made in my original post. Also the 1-2 shift is going to be the most common shift therefore putting that much more wear on the synchros.

Just watch this vid and you will see that with every shift the rpms drop less and less.

I could show you my video to but realize I have 4.57s but even so the rpms drop less and less with each shift.
