What do you guys think? Is it bad not using the clutch to shift into gears. I have been using this technique for months and its much smoother than using the clutch. I know most semi truck drivers use this method. What do you guys think?

 

you need to rev match the gears thats pretty much it.
*edit that was a joke

 

wtffffffffff
srsly...

 

i just dont have the skills to pull that off.

 

me either
kinda pointless

 

LOL! I have a spare tranny for sale, call me when you need it.

 

Its REALLLLLL easy... It does not require skills at all. Its so MUCH smoother than using the clutch.

Im asking if it hurts the tranny because i read this in another forum.

"From what I understand, doing that can damage the syncrose(sp) in the tranny even if they are done properly. And there is no set rpm... it depends on the speed of the car, the gear to and from, and then the rpms. So it is always diffrent.

I do not recommend doing it. Your clutch will last longer driving it properly, then your tranny will by doing that."

 

good luck with that

 

If its that bad for the tranny, than why is it so smooth?

Why do truck drivers use this technique?

I pretty much shift at 3500 RPM through every gear without the clutch. I have been doing it for 9 months and havent had a single problem.

In addition, there are some people replacing clutches and trannies in less than a year...

 

your telling all of us that pushing the clutch in is really that hard, and your trying to find ways around it.
its there for a reason.

 

what the.........

troll thread? lol. this cant be serious.

 

Big difference between tractor trailers and automobile transmissions... The big trucks don't have synchros. Also, there engine/drivetrain components are designed to last ~1000000 miles.

 

I never stated that. I was just asking if its bad for the tranny. I guess its a debatable subject.

I also saw this on wiki.

"It is possible to shift gears without using the clutch at all, by careful throttle manipulation. When transmissions were unsynchronized this was usually the easiest method, and still works in modern cars, although it requires a lot more practice than the usual methods described above.

Although the technique works in synchronized gearboxes, it is inappropriate in nearly all circumstances. A synchronized gearbox has a small clutch called a synchronizer (or "synchro") in every forward gear which brings the input and output rotation to the same speed before allowing them to engage. Like the main clutch, these synchronizing clutches use friction. These synchronizing clutches will allow for a margin of error when engaging without the main clutch. If the engine speed is somewhat too high or too low, the synchro will essentially take on the job that the fully engaged main clutch isn't doing. However, a synchro ring is not intended to do the job of a main clutch. Its job is to spin up or spin down just the input part of the transmission that is assumed to be disconnected from the engine. It is not intended to speed up or slow down the entire engine. Such experimentation done on a regular basis will prematurely wear out the synchro rings, which will have to be replaced."


So im assuming if done properly its not bad; but if you dont shift in the appropriate RPM, it can prematurely wear out the synchros.

 

Motorcycle drivers also dont use their clutches, is it because they dont have synchros?

 

Do a service for all z owners Please post your real info so no one on this site ever buys that car from you. If you do that to your tranny i shudder to think what you try out on the rest of the car.

 

i've done this before. Takes practice.I would never do this to the Z though.

 

ITs funny you say that, but I've had my Z since November of '02 and i havent had a single issue. Never replaced anything except for regular maintenance. The vehicle has 135k, without a single issue. That can not be said for many Z owners. Just look at some of these threads, some Z owners are replacing their clutches at 15k.

 

Truck drivers shift with that method because double-clutching can get real tedious (I drove OTR & still have my Class A). Trucking companies don't like their drivers doing that, as it causes the transmission life to shorten on the rig.

We aren't discussing motorcycles.

Shifting without engaging your clutch WILL cause undue wear on your transmission (no matter how smooth you think it feels).

So continue patting yourself on the back, but consider this... Is replacing a clutch/flywheel cheaper than a tranny rebuild?
