WELP I dunno whats the deal. I have a real problem with shifting. I will try to explain.

Okay. Say I am driving normal in 5th on the hwy, then shift to 3rd for power......then I shift back to 5th. CRUNCH!!!!!!!!!!......Why? This is a new problem for me, never happened until I put on the header, cat, exhuast, but I dont think that can affect it.

Every time I go fast in 3rd then sfhit to 5th skipping 4th this happens. I am sure I have the clutch all the way in. Please help me out. I'm becoming paranoid

Serious, what is wrong? Its is scaring me.

 

why do you skip the gear anyways? well does it do that when you shift from 4th to 5th? if not, then i doubt its a synchro/tranny issue

 

i dunno why i slipp gears. okay, but its weird, cause i have done this numerous time.....
since I have started to drive stick, 1.5 years.

its fine when i go from 4th to 5th
NO MORE SKIPPING GEARS FOR ME
do you guys thing something is wrong with my gears?

 

I skip 4th in downshifts all the time... I usually use 4th on the upshift...

I don't have that problem... must be you.

 

If you still have warranty, take it to a dealer. Mine never makes that noise... I go from 2nd to 5th all the time.

 

Normal problem, I do the skip shift all the time. Just double clutch match revs and shift, should be no problems. You just gotta wait until the syncros get up to speed.

 

sounds like synchros to me. It won't be long before your 5th gear and reverse will be gone. It should never grind or crunch even if you skip gears..

 

I skip shift most of the time in non-spirited driving and the shifts are nothing but smooth and positive. Even when done quickly.
Regardless of what anyone says, you should at least get it checked out.

 

I was thinking the opposite, but either way would explain it. If you take too long to make the shift the tranny will spin down and do that too. I've had it happen to meonce r twice when I was driving lazy.

 

The only thing is that if the guy is going from 3rd to 5th, there should be no reason for rev-matching. I mean cruising 50mph in 3rd is at about 4,500 rpm (?) and 50mph @ 5th is like 2,750 rpm. There should be no need unless he waits around too long and it's idling at 800 rpm before shifting it into 5th.

 

Skipping gears is fine when you're just driving nice and calm. I wouldn't avoid it because it crunches, but I'd have it checked out. I always go from 3rd to 5th, for example. By the time I shift out of 3rd, I'm going fast enough to skip 4th alltogether. Could very well be a sunchro problem, I'd get over to an acura dealer right away.

 

And like Erottik-R said, it should always be smooth and positive, even when done quickly.

 

Skipping gears on a downshift is perfectly normal, thats what synchros were designed for. Now skipping gears on an upshift is moronic. No need for it at all, and it destroys your synchro's too. Not flaming, just being frank as usual. Later.

 

If I'm travelling down a 45 mph road, and I accelerate through 3rd gear normally, shifting around 3500 or 4000rpm's, then there's absolutely no need for me to put it into 4th, then take it right back out and then go into 5th. However, I'm curious to know why you say that skipping gears on the upshift will destroy the synchros. I can't think of any physical way this can happen. Please elaborate. Thanks.

 

Well, I wouldn't be so harsh to say it's moronic to skip a gear upshifting, but I would recommend matching revs, as I would all up and downshifts. It will save your synchros in the long run and help you avoid the minor annoyance your experiencing now.

It's also worth noting, that some of the people from the Honda racing world don't have the kindest things to say about the ITR synchros. Bob Endicott has criticized them before as well as a few other drivers and it appears they are one of the few "weak links" (and I use that loosely) this car has. Apparantly 3rd gear is one of the weakest and it makes sense since I believe first and second have double cone synchros and third just has a single cone.

Not a huge issue and considering how reliable the rest of the car is, I think this is a minor inconvenience to deal with. Just adjust your driving style and drive they way you're really supposed to (by matching revs on shifts) and the probabem will probably go away. If it persists, then visit the dealer as you may have more serious transmission issues.

 

If you're driving fast, skipping a gear will hurt the synchro's because the transmission will be ready for 4th gear and you'll be bypassing the 4th gear synchro alltogether. 4th is there for a reason! The same goes for putting it in reverse while the car is still rolling. CRUNCH! Thats why you should always put the car in ANY forward gear before putting it in reverse, even if your stopped.

 

There is no 5th syncro to my knowledge. If there is, it has never worked on any honda that I've ever driven.

Just let the revs drop before putting it back into 5th, no big deal.

 

Right, if skipping gears on the upshift, just let the revs drop lower than usual.

 

Did you get a Type-R, Cosworth?

 

THAT'S excellent advice.

My bet is that it's crunching because you're not matching revs. When you press the clutch in third, you've got to allow the revs to fall enough to match your road speed before you shift into fifth. (And remember, if you're going up two gears, you need to let them drop A LOT.) You don't need to double-clutch, but you DO need to match revs, so you don't put all the stress on the synchros.

 

please double clutch, don't kill your synchros. and plus it feels so smooth when u get it just right.

 

6spd LT1 cars come equipped with that annoying 1st to 4th "skip shift" mechanism. Which can be a real pain in the ****. Luckily a $35 plug gets rid of it. But I still think auto's are quicker in the 1/4. BTW, I'm new around here. Hello to all.

 

rev-matching is good for smooth shifts but doesn't help synchro wear. If you wanna baby your synchro's the best thing to do is double clutch, downside is that it takes longer to shift.

 

I actually grumbled about this very phenomenon to my Acura dealer. Imagine my surprise when they pulled out an Acura "Shop Talk" that told all who read it NOT to skip gears on an upshift...

 

can someone help me figure out the difference between rev-matching and double clutching?

i shearched online about "how to" double clutch/revmatch.

what i always do when im down shifting say from 5-3, is clutch in, rev motor up, throw lever into the desired gear, and let clutch out, thus eliminating the lurch if i didnt rev match the engine.

from what im reading double clutching is the same thing just that you're putting the lever into neutral, letting the clutch out, THEN revving the motor up, and clutch in, gear lever in. what's the difference?

also, when people say "double clutch" while shifting up a gear, how in the world does that work, it makes no sense to me.
