Hey guys kinda a newbie with this. But anyway i met some guys the other day they both had g35 6mt i parked next to them while running into the store so im leaving get 2 talkin about mods etc. And u ready for this...They told me that u dont need 2 clutch when down shifting or shifting they said that u save ur clutch that way, i said that cant b good for ur tranny can it???? Am i crazy or are they???

 

They are just being a douchebag to you, of course you need to use a clutch to down shift thats what its for. Up shift maybe different, atleast on my motorcycle, never tried it in a car.
Don't listen to them next thing you know there going to tell you to flush your engine out with water when you do an oil change

...use the clutch

 

Don't listen to anyone who tells you not to use your clutch. Especially since you probably won't see these people doing that when they drive their own cars.

It is possible to upshift without using the clutch if you slide the tranny out of gear and back into the next gear just as the revs drop to the right level between your shifts... but it's not good for your synchros or tranny in general.. so don't do it.

 

classic thread

op- next time someone says something like that ask them for a demonstration in their own car, I have a feeling they will admit the truth at that point.

 

actually, you guys will be very surprised, but I am able to take it out of gear almost every time without pushing down the clutch. The way you can see is if when you accelerate, as soon as you are letting off the gas completely, there is a shift in the trans. When this happens, it's your window of opportunity to give it a little light nudge , don't force it by any means, it'll just pop back into neutral. I know this because it happened to me a few times on accident, and I realized what was happening. Given the same conditions for putting it back into gear, you could probably pull it off as well, however, you risk damaging the transmission.

 

The guys were right, with a caveat. You can downshift or upshift any manual transmission car w/o the clutch as long as you get the RPM's correctly matched to the output shaft speed.

Upshifting is pretty straightforward - you just lift off the gas as you're accelerating and quickly pull the car out of gear and guide it carefully into the next. Downshifting is a bit more difficult and takes a bit of practice. You have to pull the car out of gear just after you've starting blipping the throttle to rev-match (this will relieve pressure on the mechanism), and then you have to put it into gear once the RPM's have hit the right speed to match the output shaft. Don't force it, just guide it into gear. Again, it takes practice but it can be done w/o causing any additional wear and tear, and in fact saves wear and tear on the clutch.

 

This is something that is VERY hard to do and ive seen people go through a couple of trannys before they got it right, but when you do get it this does work. Im not sure how much wear and tear it will cause but ive been inside a friends BMW while he upshifted and downshifted without ever using the clutch and the shifts were smooth. Maybe an engineer can chime in and let us know exactly how much damage this does.

 

I can do this easily in a semi but it is a tad bit harder to do in a car but it can be done. When driving the semi I only used the clutch for starting otherwise it just got in the way.

 

I'm an engineer and I say USE THE DAMN CLUTCH!

 

im not an engineer and I coulda told you that

 

I dunno about you, but I would rather replace a clutch, and not a tranny.

 

Oh here we go again, foist of all it is possible to downshift without using the
clutch!! Ask any cross country truck driver, they do that all the time. All you
do is raise your rpm's and slide it into the next lower gear. The only
gear I wouldn't recommend is first, chances are you'll grind and it's not good for
the syncros. Most of you guys with mt, this may be your first car and you
really have to be one with your car before trying this. Just use the damn clutch, that's what it's there for....but not using it
is possible....

Anybody have a chart of engine speeds for each gear LOL???

 

Thanx alot guys yeah i think ill stick w/ the clutch and next time i will ask them 2 demonstrate for me in their car first lol
