So your saying that you need to still go through all the gears when downshifting in deceleration mode but if your accelerating and skip downshifting its ok? Sorry to sound like a real noob but this is a bit confusing lol. It sounds as if it would cause the same stress on the syncros going down and accelerating as it would the opisate way around... if not more damage? sorry to sound so lost

 

Yes, you definately sound like a noob cause your post doesn't make sense. But that's OK, we all were one once.

It doesn't matter if you are accelerating or decelerating, just don't skip gears when upshifting. In other words, don't go from 1-3-5-6, or 1-2-4-6 or any other combo. It doesn't matter what you do when downshifting.

Read woodworks old post, it explains it all (wish he was still around):

And this about shifting the S in general, it's easy to miss a gear when downshifting fast:

Hmm, I am guilty of skip shifting, but only for a week or so now. What I do is go from 3rd, push the clutch in, and while holding the clutch in I put the shifter into 4th, then put it into 5th, then finally put it into 6th and let the clutch out. I'm guessing this is just as bad. Can anyone confirm?

No more skip shifting for me.

 

I've heard that's supposed to be OK. But read woodworks posts that I left the links too.

 

As long as you wait a bit for the trans to spin down a few seconds, yeah...there's really nothing wrong with skip shifting.

The more of a speed delta between gears, the more the synchros have to work.

If you shift FAST from 2nd to 5th or something, you're probably gonna get a grind. The synchro has to slow the input shaft WAYYYYY down from their 2nd gear high RPM speed to the speed it would be in crusing in 5th gear.

This is the same reason slamming 1st to 2nd to 3rd while doing a burnout in the snow or something is really bad for the trans. Everything needs to slow down or speed up at too high of a rate.

 

No, it's not as bad. You're engaging the gears in the trans even though you're not connecting the wheels to it via the clutch.

Skip shifting is going from 1st to 4th, for example, without placing the shifter in any other gear.

 

My area is pretty hilly, so I actually coast a lot. There are a lot of places where it's is only necessary for me to reach 20-30 mph and then coast to 60 in the time it takes to accelerate on level ground. When I do this, I shift out of 2nd or 3rd and coast for awhile, then I double clutch with the engine at 3k, slip into 6th, and go on my merry way. The entire process is smooth and painless. I read Woodwork's post. It sounds like I'm bringing the main shaft up to the correct speed and mimicking a 5th-6th shift, but my tranny knowledge is still limitted.

Does this sound right?

 

Nah don't do that. Probably OK for the trans just not a very good way to drive. Shift all the way to 6th then coast in 6th. This maintains some control over your car.

 

Ok, I have been driving for over 44 years, yeah I am a geezer, and I have skiped gears in every car and still do in both my cars. I am yet to replace any of the drive train in any car, yeah a clutch at 88000 in my celica years ago, but I have no issues with gearboxes. Perhaps there is an art to this and it goes against the science...perhaps Honda has to say NO to this to prevent hamfisted drivers from abuse...whatever the reason I see no problem with it in any car I have had or do have.

I have owned over 20 cars and at least 15 have been manuals from a 3 on the column to 6 on the floor. Non syncro to fully syncro. manual clutch with cable to hydralic, rear, mid, front engine, vans, wagons, sports cars, sedans, sporty cars, imports, American built, never an issue with any car. I keep a car from 2-12 years.

As example I shift into 1-3 while going down a hill. Sometimes I start in 2 when going down a steep hill. Shift 4-6 when doing over 60. Shift 1-3 on a blvd on level ground at 25 mph. never bucking or abusing or poping the clutch, always feeling it into gear and not lugging.

I can't recommend this to anyone obviously.

 

I'm almost as much a geezer as you. Been driving for 32 years. I've skip shifted about a dozen cars, about 10 Honda's and Acura's, all up to about 100,000 miles and I have never ever had a problem with any of them either.

Up until my S2000.

I ruined the 5-6th gear syncho's after about 15,000 miles. And I am not alone. These sychro's are delecate. They improved them a little in the 2004 when the switched from brass to carbon fiber, but it's still an issue in some.

Read the post's I put a link up to earlier, and it'll explain it.

The main issue is with the 5-6th gear sychro, and mainly when accelerating hard and shifting to 6th from 2nd or 3rd. The main question is how fast still is the input shaft spinning from your high rpm engine speed when you skip to a far higher gear. If you wait a second or two, no problem. Or, if your engine rpm wasn't very high to begin with (such as you going downhill), also, not much of a problem.
