Does anyone here shift without the clutch at all? I know people who do this but not in the CL. I am under the impression that its not good for the clutch unless done perfectly. If anyone does shift without the clutch, at what rpm and which gear?

 

im not professional here, but i have a couple of buddies with evos and sti's.. i believe the term your looking for is"no lift shit". which basically is what it states no life shifting. Im like a hundred percent sure, its terrible for the car. The guys who i know that do it are usually and very high rpms. id say over 7500rpm definitly and they usually do it i think after 3rd gear. I would not recomment it, but like i said im no pro, but i figured id throw my in there

 

Its not as bad for the clutch as it is for the trans itself. Don't do it. You're driving a CL, not a track car with a trans with straight cut teeth.

 

he is def rite..i forgot to mention that my friends cars also have different clutch and flywheel set ups that are not stock

 

Dont do it. I did it couple times by mistake and i ended up paying 3k for the tranny rebuilt and change all my 6 gears.

 

I've done this a bunch of times on my cars. Honda's generally don't like this, my toyota its VERY easy to do this.

But i agree, its not good for the trans. it doesn't effect the clutch at all. infact it saved the clutch.

Really, unless you rev match it, it can cause gear grinding, which can cause synchro problems, plus other internal stuff.

I'd just use the clutch, its much less stress on the trans.

 

There is a sweet spot in the gearing where it will slip right in at the right rpm. Ive done it a few times with no grinding slips right in like the clutch has been depressed. Get it wrong and your grinding.

 

this is not "no lift shift". that's when you shift at WOT from one gear to another, still using the clutch, but not lifting from the throttle. the new Cobalt SS turbo and HHR SS turbo feature this from the factory, i'm assuming with some type of ECU algorithm's to not mess up the clutch.



however, clutchless shifting can be done fairly easily if you aren't forcing anything into gear. you must do rev matching like downshifting, though. i would say 2nd @ 3000rpm goes into 3rd at about 2300rpm. i've done it (as a trial), and yes, it can be done without harming the car.

 

No dog clutch in the CL-S so I wouldn't try it.

 

just drive it like you were taught. it won't kill your tranny and save some gas???? haha

 

I've never tried it and seriously don't want any issues, however one of my buddies is going to show me how to do it in his Forester. I highly doubt I will ever do it in my car.

 

I do it all the time... on my bikes. The big differences are there's far less torque going through transmission, the engine revs up 2 or 3 times faster and their sequential transmissions so there's very little internal mechanical movement required to switch gears. You just apply pressure towards the next gear and chop the throttle for a split second. That's enough for the transmission to go from push to pull and the rpms of the engine to dip down several thousand. Enough to cover the difference between the very close ratios. When the weight goes off the transmission it slips right out of gear and you hold just slight pressure until the ratio is exactly right and it just slips into the next gear. This all happens in about a half second mind you and there's only small disruption before she tries to bolt out from under you again.

In your car, the rpms do not drop as fast so there's a lot more grinding while you wait for the ratios to match up. It slip right in when it's right but you have to know what your doing and already be giving it just the right amount of gas so you don't engine brake or accelerate to hard. Failing that gears will really slam home and that's obviously not good for the engine. Since there's so much more metal involved there's a lot more energy behind all the moving parts so it's much more susceptible to breaking things when one parts inertia disagrees with that of another.

It's not at all worth it.

 

yeah i think i heard about that in the new cobalt...the ecu interupts the throttle while the gears are being shifted all while at WOT. doesnt sound very fun i think it would feel a bit wierd to shift gears while still hitting the throttle. isnt that kinda like double clutching? i could be crazy

 

I've done it on civics and preludes and accords, but not on a cl or a tl-s 6mt (yet). on the hondas, i usually get it up to about 3500 rpm, then do it, it drops in perfectly, no grinds at all. i guess it just takes knowing your car, but like everyone else says: don't do it. for me it was pure experimentation.
