i have been using my clutch other than the time i stated in my initial comment when i opened the thread. however, yesterday i tried to go from 2nd to 3rd and had a small grind so0o0o i will no longer be trying because i don't want anything to be put to risk ya know. however from 1st to 2nd is like butter. but i'll just use the clutch as usual i have no problem with doing that at all. more so, i disagree with qwikeredline however... driving without the clutch does not make you the best driver or driving with the best. i give kudos to those you can clutchlessly drive a 5 speed. doesn't mean they can launch better than i can or handle the car better than i can. i'm not trying to start a disagreement i'm sure people will agree with me even excluding your own and my own ego... i'm not saying i'm the **** at driving a cobalt. because there is ALWAYS someone out ther better than you or me. the odds are far too great. however i do kick ass in Call Of Duty 4: World at war lol so whoever wants to do some Hardcore TD Match feel free lmao my girl hates me when i play that. thanks eveyone though for your comments. i like how this thread turned out

almost read the end of that wrong lol

 

it's accually i highly used technique used when driving a semi
honestly i tried with the clutch in a semi and found it harder

i also do it quite a bit in my s10

it easy to do in my cobalt i just dont it takes thinking

Just remember not to crank down on the shifter
and for down shifts give a little gas to bring up the RPMs

It doesnt hurt the car at all exept for once in a while when it grinds, its gonna happen.
Id love to see someone do 100 clutchless shifts and not grind onces

 

agreed. i talked to my brother-in-law he drives a semi daily... he is the beer man of philly basically for the past 15 years lol. and he said most of the time in the city he doesnt use the clutch. also they just got new trucks not to long ago that you the OPTION of being auto or stick... also with no clutch even in there. kinda like the m3's basically in a nut shell. he said yep

 

I shift all the time with no clutch. 2,700 RPM goes right in. 3,200 when down shifting.

 

i get sketchy doing the rev matching downshifting i never tried it. i always blip the throttle and use the clutch just for the sake the syncro's. however i have been using my clutch it just makes me feel uncomfortable when i dont use it. even though its nice and smooth gear switching when i test it without the clutch. idk i'm more comfortable using the clutch. its how i taught myself years and years ago

 

Like many have said if you know what RPM to shift at it will not harm the transmission. I have too many problems with the transmission in my LS to even think about clutchless shifting. In my old 61 truck I did it all the time.

 

I drove around for almost a month using just one foot,clutchless up and downshifting at all speeds, I even had people in the car and noone noticed till I told them.....

Clutchless shifting when done PROPERLY is perfectly fine, and if you can master it you will make your trans last longer as well as your clutch.


If you do it right its actually better than doing it half assed with the clutch.

Do NOT hold pressure on the shifter till it goes in......this is doing it wrong, this WILL wear out your blocker rings, and cause uneven wear on things like the forks and shift rods depending on how much pressure you use.

^^^^^This.


Youre doing it wrong, pulling on the shifter any harder than when you shift with the clutch to engage the synchros and make them do the work is what wears them out, if you do it properly it snicks into gear just like if you had used the clutch properly. Pressure on your shift lever is BAD>

 

To sum up, Maven said it right (so did I)

Shifting gears is a three part motion with the right hand. Out of the gear you are in. pause. shift into the gear you wish.

the ratio split is different between every gear. Out: Upshifting, the timing has to be such that as you shift out of gear you simultaneously lift off the gas, this helps the fork move the gear to neutral. Pause: During the pause wait for the revs to drop to the correct gear/engine speed. Shift up to the next gear.

The ratio split determines the gear/engine speed.

Shifting down: Out: out of the gear you are in, (simultaneously lift off the gas) Pause: Blip the gas pedal to raise the engine revs to the correct gear/engine speed.

For the same constant speed of the car, driving at say 50 mph in 4th gear: upshift to fifth requires about 800 rpm split DOWN. from 4th to 3rd: downshift requires about 1100 rpm split UP

The exact rev numbers are different depending on gear ratios. The Deltas are not bad cars to practice in, but something with a slower revving engine and more robust transmission would do. A clark or new process 4 or 5 speed trans in a 5 ton with a 2 speed axle would be a good training vehicle.

Remember while I have my teaching hat on:1. most drivers shift too fast. 2. Most drivers shift too hard. 3. most drivers ride the clutch.

MAVEN and qwikredline summed everything up.

 

When the slave cylinder went on my 69 Corona half way across town I got quit acquainted with clutchless shifting. Had to shut the car off and start the car in first gear to get going at every intersection LOL. The old 4 speed in that Toyota was pretty good for it though.

 

you got the last question right! the other way on a car with mutliple cone synchromesh, is to loush the shift lever up against first gear, clutch engaged, the car will start rolling, keep pushing and when you reach optimal vehicle/gear speed the gear will engage and off you go...

 

had a bad slave on the car was driving home 30km's with no clutch luckily no stops just windy back roads.

 

*first post* haha, yeah so i was just gonna say, in my recently sold nissan maxima (96 5spd), i could do all the up and down shifting with no clutch... also, i was able to get it into first from a stand still with no clutch either. although that took a while in a parking lot trying to match revs while pushing against 1st gear, prolly wasnt the best on the syncros... also, on the up-shifts, ive done it as high as 5600rmps, and i didnt even pause in the middle, just a quick pull and it came out and went into the next gear quick and easy with no grind *3rd to 4th if i remember correctly*. i was kinda in race mode right there, doing a bit of quick acceleration *obviously, why else would i rev that high haha!*

but anyways, i was wondering if anybody tried it under heavy acceleration with our nls *no lift shift* and if they had any success?
