Here's how Honda uses the terminology:

"Final Drive" is the ring and pinion in the diff. It's 4.10 and has not changed since the first S2000.

"Secondary Gear Reduction" is an extra gear set, always engaged, in the transmission. It was 1.160 for AP1, and is now 1.208 for AP2.

Thanks

I used to get confused a lot. Because I've heard different terminologies. So I guess the "thing" in the tranny is secondary reduction gear, and the "thing" in the LSD is final drive axle gear ...

The AP2 is more resistant to an overshift. It has a slightly more conservitive redline (based on piston speed), heavier flywheel, and stronger valve retainers.

I don't know about the celica, but to do a money shift on the S2000, you have to be well over 60mph. So its unlikely unless you're really pushing the legal limit

Remember to shift slowly and carefully on the highway, and you will be fine. If your not positive about which gear you are in, don't lift the clutch.

The problem comes from the situation that when the driver is at redline on 3rd and tries to shift to 4th, but ended up shifting to 2nd. Redline 3rd >>>>>>> top speed on 2nd gear

Right, highway speeds (70+mph). If you're hitting this between redlights, then you're really pushing the legal limit (again ). Slow the ef down until you can tell the difference between 2nd and 4th. Keep it under 60 if you're going to "bang gears" and you won't have to buy a new motor.

Well ... we all know racing on the streets is illlegal hehe

But anyway, it happens on track days too. Even experienced drivers do that as well (though much less often ... or they often figure out that they are in the wrong gear before they fully release the clutch)
