I know this is possible, and I know there is a 'right' way to do it... but I'm not sure I'f i understand the concept right. Somehow you're supposed to know when your engine speed and gears line up in each gear and at what rpm... so you can just slide it to the next with no clutch...

Anyone want to give me some advice on this one?

 

havent triyed it yet myself but my friend owns a 97 ek and he knows how to do it so ill ask.

 

I'm not trying to "hate" but what's the point of doing this anyway when you have a perfectly good clutch pedal right there?

The only time I ever do this is when I'm driving a tractor [diesel truck].

 

yeah you've basically got the idea. though its alot easier said than done obviously. plus too it takes a little confidence which is hard when you're worried about grinding gears. My buddy's go a mk3 Jetta. we were out cruisin one time and he was able to get around town doin' it up through 4th gear. He was pretty quick at it too once he warmed up. It was impressive to see, but yeah not sure what the point of it is. I guess its a good sign of a driver really knowing their car.

 

i have a 94 integra and i can clutchless shift.. all my points are between 4000-5000 rpm

 

I would think it would make for better acceleration, less time between gear changes.

 

WHY!?! The clutch is there for a reason.. durrr

 

its there to force what happens naturally in the gears anyways... you just have to know when they line up to do it without a clutch.

Powershifting increases the acceleration of your car.

I understand what you are asking, but I haven't tried it yet.

 

Very stupid idea man ... just work on shifting WITH the clutch a little more quickly.

DING!

 

guess you don't want your syncros lasting too long. the only reason you should ever have to shift without the clutch, is if you clutch dies, and you need to shift into another gear

upshifting is very simple to do, downshifting is a little tricky, but also can easily be done.

if you feel like trying it out, do it at a low RPM, under 2500

Which is why I haven't done it. I read up on it and talked to some people around my area. I just added the short shifter and a heavier shoft **** instead.

 

my dad showed me the no clutch shift trick when i first started driving. you can do it w/ any car. how he taught me was to get the rpm's a lil higher like above 3500 give it a lil extra gas, put it in neutral, rev the engine a lil bit, and push the shifter into gear, it's kinda tough the first time u do it cuz u put a good amount of pressure on the shifter but it does slide right in gear. booyakasha. he didnt tell me the syncros or anything would wear fast but i hardly do it.

 

what if your clutch goes completely out...and your trying to start the car.. do you just rev it up and throw it into first. to me, that sounds like it would do really bad things to the synchros..?

 

My friend use to do that alot~.... and he lost his 2nd and 3rd gear, it wouldn't go in.... (if you figured his tranny was f**ked!)

 

if you do this right the syncro's actually have less work to do and wear less than if you shift like every other non driving retard.

this is only something you'd want to do when driving normally or on a road course (downshifting while using your left foot on the brake pedal) , its way faster to shift with the clutch.

80% of the time, other than starting off or putting it in to 1st gear i dont use the clutch. i learned how to drive manual trannys on tractors and such that didnt have syncros so you had to rev match whether you used the clutch or not.

 

I used to be able to do it with my VW bug (over 10 years ago) but I wouldn't try it on my FG.. Get ready for pointless grindage.

Powershifting ain't the same as clutchless shifting. and btw powershifting does not always increase acceleration. If you powershift with a fast car you could overspin the tires and lose acceleration. Powershifting can also wreck your tranny if you mis-shift.

 

Thanks but no thanks....y'all trying this on '06 and 07's? Try explaining that to the dealer when you try making a warranty claim...I guess if you can, the more power to you, but I will stick to the 'ol fashioned clutch

 

I can do it quite easily in my EG's, but doesn't work so well in the FG. I'll stick to using my clutch

 

I what you're talking about.
My friend in his 240sx, he was
able to slide from 1st gear to 2nd
without using the clutch.
I know, honda isn't nissan but
maybe its the same concept?

 

when was the last time u saw proffesional drivers do this with their cars? thats some careless crap ur trying to pull! if its between 4000-5000 what the hell is the use?! ur better off just shifting gears without releasing the gas, not that i say u should to it cus u would BBQ ur clutch! just drive normally trannys are really expensive to fix. . .

 

um... ever watch rally drivers that dont have the option of a sequential clutchless tranny (like the wrc).. if you are using one foot on the brake and the other on the gas you have to rev match to change gears. thats pretty much the only time you'd ever see that done when racing, its much faster to WOT shift if you are drag racing or heel-toe when downshifting under braking on a road course.

i generally only do this when driving slow/normal, when hauling *** its faster to use the clutch.

 

have you ever watched a professional driver? rev matching completely eliminates the clutch upsetting the momentum of the car during down shifts.

It won't work from a stop. I'll try to explain, although it'd be easier if most of us have disassembled a manual transmisison or at least knows very well how the internals work.

Firstly, the synchros' job is to match the speed of the gear to the speed of the shaft, whether it be first, second, theird, etc., on either the mainshaft or countershaft inside the transmission.

This happens in a split second but it would increase the life of each synchro if this rpm match (between a gear and the shaft it spins on) had no torque behind it. It can spin, but no force should be applied to the gear or to the shaft. This is done with the clutch. The clutch disengages the engine's torque from the transmission, even though the trans is still spinning due to the car still rolling. This separates the engine's torque on the transmission internals from the torque applied by the rolling wheels. The synchros take care of the rest.

Another way to eliminate the difference in torque is to rev the engine so that the torque it applies is equal or close to the torque applied by the wheels rolling. For example if you try to get second gear from first without the clutch, you'd have to ease off the throttle in first until the torque difference between first gear and the mainshaft are equal. It should slip into neutral. Then to get in to second, you'd have to anticipate how much faster the mainshaft will spin when second gear is engaged and rev the engine accordingly. When the torque difference between second gear and the mainshaft is at a minimum, it will slip into second.

So while it may not be beneficial to shift without using the clutch, knowing the principles of clutchelss shifting "should" increase the life of the synchros even when using the clutch. Remember, they still have to match speeds for you, the clutch just gives them that extra margin.
