Oh ya, anything that comes from HTG is solid, im sure he must have installed the AP2 retainers, they are supposedly stronger and more reliable.

+1 for HTG

I would have thought if you did a "true" over rev, you wouldn't have been bouncing off the rev limiter at all. Gas cut rev limiter isn't going to do anything against a mechanical over-rev. If it was really bad, you would have seen revs shoot straight to 10k+. So it sounds like you got lucky?

Start listening to your girlfriend.
Thread is about potential car related issues, not relationship problems.

If you slammed the shifter hard enough you may have bent the selector a few microns. Im not saying this happened or is even possible. On second thought ,I think it may be possible. That could explain your belief that over time ,shifting returns to normal as the shift fork is gradually bent back to normal.

^^That would only be possible by someone whose stature would require the jaws of life to get them into and out of an S2000.

As to the poster who stated that it could be my pressure plate:

My belief is that if the pressure plate was faulty, all gears would require a little force to come back to neutral...

1st-4th = buttery smoothness

5th is the only one catching (slight hang with car moving)(requiring FORCE to pull out of 5th with engine off w/clutch in or out)
Yeah, given that it does the same thing when the car is not moving, I would say that the pressure plate does not sound likely anymore. What I can't figure out is why 5th? The only thing that 5th has to do with 2nd (the gear you downshifted hard into) is that they are both in the tranny , one is on the counter shaft the other is on the mainshaft

My guess

Money shift -> uber high revs -> rocked engine hard in its mounts -> tweaked engine or tranny mounts -> tranny not properly aligned -> hard shift

^You were right & I was wrong:

You - 1, Me - 0

Even tho the retainers looked to be in perfect condition, I did a compression & Leak down test today, because I'm paranoid.

225, 225, 230, 225

Each cylinder slowly leaked down and stabilized about 5psi lower in each cylinder from the above readings. I figured this was just excess pressure from turning the motor over.

My conclusion is that my motor miraculously survived a massive over-rev; but I will continue to check my retainers at least every other month or so.



I still have the 5th gear problem. And I do not see how it could be the clutch, but my clutch buzz is louder at idle, and I can hear a whirring sound that sounds alot like clutch buzz while cruising in any gear. Is my clutch causing 5th to be notchy? Who knows...
