shifting without the clutch...
 

So I've heard it can be done. But can it be done on newer cars, namely the z?

yea, you have to steady the rpms at the right speed and the gears slide together.

I wouldn't bother trying it, just to save the life of the tranny by not grinding gears trying to learn.

The idea is to apply throttle so that as you slide the shifter out of gear, the rpms stay where they are, and then lower the rpms to the appropriate speed to engage the next gear. seems simple, but its only useful if your clutch ever takes a crap.

Hmm..that's cool..now since our car rev match on downshift would it not be easy to shift down w/o the clutch as long as you have the right rpm to get it out of gear?

OP, can you not shift?
lol...
Why'd you get manual then?
Do it the right way!

Please try and report back.

:wtf2:

:iagree:

I did it when the trans in a former car took a dump just to limp it home. I'm sure someone can learn to do it quite well, but I sure had issues with it.

Also popular amongst semi-trailer truck drivers ("18 wheelers") because of the larger amount of gears they have to get through... but they also spend a good bit more time driving than we do.

It gets annoying for them to keep using the clutch.... much easier to ruin the trans...LoL

SRM cant be used if you try this method because you have no throttle control. you would need to turn it off. the idea is to raise or lower the rpms BEFORE the gear is engaged, SRM revs after.

What a helpful comment :facepalm:
Anyway other posts sum it up. I can't do it that well on my friends car but he can do it just fine whenever he does. I guess it just takes practice...

Thanks for the info. Btw yes I can drive manual....was just curious and always like to learn new things that just may be used sometime. Thanks again! :tup:

Truck tranny and car tranny are different though.. one has synchro mesh the other doesn't. Trucks really don't need it for the gears other than say 1st and Rev.

This thread seems to pop up on all kinds of forums. I was reading an E90 BMW thread where they discussed the very same topic. The posters above are correct in that it is possible if the RPMs are matched, but if not....:shakes head:. I wouldn't dare try to do it, but if you are not worried about messing up the tranny then go ahead and try it.

:facepalm:

1. Borrow a friend's MT vehicle.
2. Ruin his instead practicing.
3. When your clutch takes a dump you are prepared.

+1 :bowrofl:

I was hoping to practice that very thing, but unfortunately my friend doesn't wanna lend me his m3, and my other friend doesn't wanna lend me his 335i, and the rental companies do not have MT cars. Oh, and I'm not stupid enough to try it on my Z :D

:facepalm:

It *can* be done, question is, why the hell would you want to trash your transmission...?

:icon14:

I learned on a beat up POS at work one day, years ago. Its kinda like those survival shows on TV, you can learn some cool stuff, but will it ever need to be used, probably not! Same thing here.

My thoughts exactly!Why in the hell buy a nice sports car and then ruin your trans?
Other then acting childish and reckless why?

Why risk messing up a good thing?

to me it would defeat the purpose of owning a car with a clutch. i bought a car with a clutch because i want to use it :)

I haven't tried it in my z, but where I work we have a geo tracker that whenever I drive it I never ever use the clutch, I just rev match it and it slides right into gear. Its not worth the time save in the Z though.

When I had my 350 I was told by a couple reliable sources (personal mechanic, Nissan service reps) that it was in NO WAY bad for the car, and I have never had a problem with transmission for the three years I had the car. Now keep in mind if your doing this, it does need to be at the correct rpms otherwise you will hurt your tranny. It should come out real easy, and slide into the next year real easy, if you feel pressure your doing it wrong. I rarely do this though to be honest, and when i do its pretty much only from 3rd to 4th when I'm feeling lazy driving around town.

I understand why many people are commenting saying "NOOOO" but its probably because unless you do it correctly your going to ef something up, and it is kind of pointless. Also, advice like this I wouldn't take from Z drivers on a forum, your best bet is to find a friend who is a mechanic or at least a mechanic you can trust and talk to them. That's what I did.

Btw - I DO NOT have the sport package on my Z

Well the thing is, it is pointless and it is risky because you can screw things up if you're not doing it right. It's best just to know the science behind it so if you ever get into a situation where you HAVE to do it you are armed with the knowledge to make it happen.

I do clutchless shifts on my motorcycle when i'm being a bit lazy or when i'm really winding the gears out hard on the free way but it's a wet clutch sooo :D

i did it for a week in a rent vehicle. It was great, i got around without the clutch for 2nd to 6th gear in a corolla... (can't remember if it was a 5 or 6 gear car).

I'd never try it for my zed but

it can be done, but it's easier to just press the clutch pedal.

i got to know my old g35 so well that i could upshift and downshift without the clutch and never grind... i was even able to downshift to first at about 3 mph without the clutch too... id do it messing around all the time. I havent tried it on the 370 but I'm pretty sure any manual tranny has times where the syncros are open you just need to feel it out and know where it is...

def pointless and not all that smart to do, but if you do it right its no different than pressing the clutch in to allow the tranny to shift.
