Question STi 3rd Gear

I was wondering if anybody else with an STi had strange things going on with 3rd Gear. It seems I have to push my clutch all the way down for it to go in smoothly. I shift around 2.5K to 3K RPM from second gear to 3rd and I often find myself having to shove the clutch all the way down for it to not feel like it's grinding. A couple times I pushed the clutch in (with about 1 or 2 inches left before it catches) going to 3rd and it felt like it was going to grind. Is this normal for any of you? Just curious, don't know if I should take it in =/

Mine does the same thing. It just depends on how I shift. Practice, practice...

If I remember right, 1st and 2nd have more synchros than 3rd. It might just feel different shifting to 3rd because of having less synchros to smooth out the shift.

You should be pushing the clutch all the way down to the floor with every shift, though. At least, that's how I was taught and works best/smoothest for me.

I strongly agree.

what would be the possible advantage of not pushing the clutch to the floor all of the way?

I must be a stick noob.

1st and 3rd have double cone synchros, 2nd has a triple cone synchro.

It goes in like butter for me, I'm shifting at 2.5-3k aswell.
it does take a little time to get use to the short shifter. you will be fine.

some cars that have an extremely high clutch, the last 2-3" that you push in all the way do absolutely nothing. so by pushing the clutch only half way, you can reduce the movement of your foot and potentially save time during shifts... but it depends entirely on where the clutch (dis)engagement points are on the car.

I experience this from 1-2. Just takes a little adjust on how you shift though.

I noticed the same thing in fourth. The cure for me is to shift faster. It only happens if I get lazy and shift real slow.

Ah, all good. I talked to one of the STi owners today while I was at Union City Krispy Kreme and he said his 3rd gear did that too. I guess you guys are right and I have nothing to worry about!!

I haven't had any issues with mine other than finding 4th can be difficult from 5th (sometimes goes into 6th instead). Getting better at that though.

In my old car I got to the point where I would really know the clutch point, and go down just beyond it, shift, then let up. Now that car (a Miata) had a really short shift -- the STi is way longer, and the revs don't drop as fast either, so upshifts in the Miata were much faster. I'm gradually learning the clutch point on the STi, so I'm going down a little less, but still farther than necessary. Personally I think there is an advantage to not always putting the clutch all the way in. It doesn't really hurt to push it all the way down, but it is extrenuous movement (as long as you really go down far enough to completely disengage it, do your shift, then let it out after your revs are matched).

I experimented in the Miata with clutchless shifting. Interesting, but not a wise idea for longevity. It's all about rev matching really well and not forcing anything. I never did it at race speeds though, and the Miata has a blistering 128hp at the crank which means a lot less load on the system.

Shifting at 2.5K-3,000 RPM ? man, that's more of an idling speed !





Basically the less clutching you do the more work the synchros do if you don't match revs. That means tranny wear. Keep up what you're doing for 60,000 miles and you'll be more likely to need a tranny rebuild than the rest of us.

Just learn to clutch faster and jam it right to the floor. If you shift at higher RPMs it also works much, much better.

I thought synchros are only used when you're pushing the gear selector into gear? That would mean that your synchros have nothing to do with your clutch work (unless you're double clutching).

if the clutch isn't fully disengaged, the synchros have to work harder, since there is extra movement in the system. These aren't the right words here, maybe someone else can jump in and explain better.

Sometimes this can actually work to your advantage, if your synchros are worn a certain way, from what I've seen. I'd agree that it's better to push to the floor and prevent the extra wear on the synchros in the first place, though.

I also noticed a definite "snick" when going from 2nd to 3rd when I first got my STi. It wasn't a grind, but a "snick." That's the best way I can describe it. A slight resistance... like a click-stop. However, nowadays I don't notice it anymore. Probably got better at shifting with practice.

my 3rd is kinda like that too

i once mishifted to 5th from 2nd. i knew it was 5th so i took it back to neutral and tried to find 3rd.

was very notchy.. then it grabbed hard.

but that was first 100 miles or so..

a lot smoother to shift now.
