Ok well I've seen about 3mm threads about Honda Si transmission grinding issues... etc etc

Just something i've noticed is that .. the Clutch plays a major part in this due to the engagement points.

Every SINGLE.. Si' i've driven has a different clutch feel or point of "engagement" which i think factors into the "missed 2nd or 3rd issues" due to ..

depending on your driving habits... and style...

Would explain why some people have it and others don't.
(considering if your clutch is not engaged fully, you cannot put it in gear fully and grind)

Some of the people that can validate this are

Greddy Dantegra
Michael Bolton
Poljana

etc etc All of us after driving each others cars noted immediately that the clutches were night and day different & everyone had something to bring to the table

1 was turbo, 1 was supercharger, 1 has NA mods, 1 was still a 3000 miles etc etc


I dont know if you trust a local that you know with an Si but its definitely something to check out.

I've driven countless brand new Si's on the lot and I can definantly relate to everything youre saying here Mike.

 

I can also relate.
i drove 3 different si's before i drove/bought mine and the clutch felt different on all of them.

they were all brand new to

 

Very true.

I think the vast majority of people who have grinding in gears are actually just not pushing in the clutch fully.

I've noticed EVERY time I grind 2nd or 3rd, it's because I left off the clutch too quickly or didn't depress it enough.

It also makes sense that what I just said would be the logical answer because 2nd and 3rd would be the ones you're grinding because those are the two you're going to be trying to shift into the quickest when trying to go quickly.

On top of all that, from 2nd to 3rd is a really long throw of the shifter, which would explain 3rd being such an issue for most.

 

I noticed the same thing.. the other SI's I drove all "felt" a little different.. I don't have that much experience with hydraulic clutch cars (always had cable on mustangs and old hondas) so I just thought it was a hydro thing

 

I drove paul 06blaksi's car last night the clutch felt a tad diff but the big diff for me was him having the comptech ss shifts were so much better then stock makes you feel like a better driver on the spot i need 1.

 

Ive only driven 3 as well. My own 2 and Type X's. They all had a different feel to me as well. Who knows why they all felt different, maybe driving styles on a daily basis, mods or routine maintence, who knows. I think most of mis-shifts or grniding issues can attribute to my own driving error.

I agree. The few times I grinded my gears was me not pressing the clutch in all the way.

 

when driving fast I only have trouble going into 3rd ( I miss or get hung up) but when going into R if the car is not stoped it will grind (ie) on a hill drifting back slow.

I haven't gotten the chance to really drive any other FG's other than the two that I test drove before I made my purchase but even in one of the Si's I test drove I grinded 3rd gear while not really focusing on shifting.

I still occasionally lightly grind 3rd gear but like you said I think its mainly because of my own driver error. Typically when I'm trying to shift quickly into 3rd when accelerating or shift into 3rd while I'm distracted or not really focusing on shifting and let off the clutch a little to quick.

I have heard replacing the transmission fluid sometimes helps is this even true?

it'll help, but it wont make it go away compeletly.

 

Anyhoww... your clutch grabs alot lower and better than mine Mr. H8R

I got a ClutchMaster Stage 3 Clutch last week, going to get it install at RPM in 2 weeks. Wanna meet up?

I still disagree with this grinding theory. Well maybe I'm talking about a 2 stage second to third gear shift. But it always happens no matter how I drive and I have experimented with different ways of shifting, it just always happens. You have to really push and feel 2 clicks for it to truly be in third for the first few second to third shifts in the car.

 

Do you have single or double cone synchros?

I, along with many other S2k owners had a problem with griding 1st -&gt; 2nd gear at high rpm.
The issue came down to a heavy clutch/flywheel rotating assembly along with a weak 2nd gear synchro. The grinding would occur when you'd shift hard and bypass the synchro. Do it enough, and you start to mushroom the heads on 2nd gear.

The way to avoid this is to either (1) lighten the rotating assembly to lighten the workload on the synchro, (2) beef up the synchro (was done in later s2k revisions), or (3) don't bypass the synchro by shifting so fast.

(3) was the easiest and cheapest solution. The proper technique is to apply light pressure from neutral and give the synchro time to do its job. When it's ready, it'll slide into gear with little pressure. Forcing it into gear = bad.
If you do it right, the force it takes to go out of gear and into neutral is the same amount it should take to go from neutral to the next gear -- its very little.

If you want to further reduce wear on your synchros, you can learn to revmatch and double clutch your down shifts. This will greatly reduce wear on your synchros and clutch disk.

 

Just to clarify, the issue in the above post has nothing to do with the clutch release. The S2k 1-&gt;2 grind will happen as you move the shift lever into 2nd while the clutch pedal is against the floor.

 

Well said

Never ever ever shift into reverse while moving, even at 2 mph. There's no syncros for reverse, which to my limited understanding helps the gears match up prior to engagement so there is no grinding. If you're moving at all when you shift into reverse, you're just clashing the gears together.

I'm not a big fan of short shifters in general. It is important to understand that with a short shifter, you are likely to increase the workload on the synchros. They will have to do the same amount of work in less time, meaning they will wear out faster. Same goes for weighted shift *****.

That said, I have a Mugen shift ****, with urethane shift bushings. The throw is slightly shorter than stock, and the bushings reduce play in the linkage significantly. I wouldn't be against installing a short shifter in my car, but I double clutch and revmatch almost all my downshifts.
It's a very good thing to learn (at least the revmatching). For some it may take days, other months. When you have it down, you'll be able to shift much faster than you could normally and still be saving wear on your clutch and synchros.

A short shifter isn't a bad thing, but understand that if you go around slamming the gears, you aren't doing your synchros a favor.

 

no problem with my 07 si sedan right from day one. no problems after the short shifter also

 

i made a habbit of making sure the clucth is to the floor every time i shift, and it still happened. if people only drive their car, a different release point in another car wont effect them in any way shape or form.

Your Lucky then !

 

ive missed second a couple times. really sucks. i would have to say its simply not pushing it in "allllllll" the way.......

 

thats not it. i no the difference between missing and this other thing that used to happen. i watched the shifter pop once. the shifter was in 3rd all the way. released the clutch and watched the shifter bounce out and heard a grind. It only happened when it was cold out and car was cold.

And the clutch wont go past the floor board. first couple times i figured i was doing lazy shifts. either clutch or not getting it in gear all the way. thats why i made sure the clutch was to the floor. Besides that my clutch only has to be pushed in about 2" to shift. Quit doing that though because i dont no if thats bad for it.

 

My car has over 6000 miles now and i have never grinded or popped out of third or second..... but it is notchy going into third sometime...
