clutchless shifting

ever since my friend got back from vacation, he was talking about how kool it would be to learn to clutchless shift his car, and how a truck driver was telling him how he shifts his rig with out the clutch all day long.

so me being a dumb ass that i am, i desided to prove to him that i'm away better driver then he is, so i took my aveo out on to a big parking lot, and started practicing.

i can now shift all 5 gears without the clutch, its smooth as butter, and nothing grinds, but i can only do it at low rpm's for now.

who else is doing this in there aveo? or ever done in any other vehicle?

Ive done it redlining every gear, you just gotta wait for the rev to come down to the right spot.

Upshifting that way is ez, try downshifting from 5th to 1st without the clutch tho, thats a different story.

this sounds really bad for your clutch and all those fun gears

Please do not attempt this unless you know what you are doing or still have your warranty.

they wont replace that under warranty... clutch is not covered.. it would probably shatter before the tranny.

i still wish i have the factory "upgrade" clutch...

why are you guys talking about the clutch, clutchless shifting does not involve the clutch, and if you do it right, and transmission acts like the clutch is pressed

the clutch is still what carries the power through to the trans.. if you jamb it between gears (misshift) or dont rev match rpms properly. in this car the clutch is the weakest link. and can and will still glaze or shatter from the power grab of the transmission

all you are doing is "floating" the gears instead of "floating" the pressure plate... the clutch is still holding the power, it is not bypassed. you are just eliminating a step in shifting for "speed"

I wouldn't want to try that because I know that it would take lots of nasty grinding before I'd get the hang of it. Interesting idea though!

It isnt really hard at all, ive done it many many times without problems, like its been said u just gotta know what your doing, my brother has a Mazdaspeed 3 and he shifts it without the cluth 90% of the time because he has a bad knee and has some trouble pushing the clutch, its not hard.

I tried out the clutchless shifting today. I got it on my first try, but had a bit of grinding on my second clutchless shift. I somewhat knew how to do it based on what I had been told, but had never seen it done before.

Oh well. It is neat, but I probably won't be using it much.

I almost always use a basic form of clutchless shifting....

Always when slowing down to stop at a stop light, I wait to feel the point where the shifter will just slide out of gear.

Its one less clutch press which can help, in heavy traffic.

I tried some full clutchless shifting today....you have to be really confident and exact to get it right. I got some grinding, and probably wont be doing it much.

I dont think Its not any worse on the clutch than regular shifting if done right. (normal speeds, no grinding or clunking or lugging)

Its not powershifting.

I used to clutchless upshift and downshift all day long. Probably done over 20k miles city without the clutch which includes downshifting. I just did it for the fun of it and the fact I had a 6 puck clutch w/ 1200lbs pp so it was much easier.

It's a good trick to know when you're trying to do things with your hands and need your legs for the steering. lol

I would not recomend doing this to anyone, you can shift w/out a clutch, but you will wear it out that much quicker. I drive big rigs all the time at work and they are a big difference. Big rigs have whats called a clutch-brake, which is a gear that spins constantly and you can feel when you shift gears like a finger running on the gear slowing it down for your speed selection. Not to mention they have air lol. By the time you get good at shifting without a clutch in your aveo you will already have screwed up enough times that the damage is done.

Clutchless shifting will do no harm to the clutch. If it's slipping enough to become glazed, due to abrupt application of power, there's a wear issue here. The biggest reason NOT to do this is the fact you're placing incredible stress on the transmission syncronizers. They were not designed to bring gears up or down to matching speed under load.

+1.

ok, so it was kool, but got old, im back to shifting the right way 8)

its easier to eat, text, and drive with an auto trans :lol: :lol:

good point! I do hate getting phone calls while I'm in the Aveo cause I dont have 3 hands. But I just cant part with the 5-speed shifting goodness!!

u shouldnt be answering your fone when ur driving anyways

That's why you need to step up your game, stay with the manual, and get a kenwood headunit w/ bluetooth. It works fantastic.

Can upshift 1st-5th in my Escort but not good enough to do it downshifting just yet. And yeah...I did learn floating gears in a truck all day long. ;) Maybe I can master it in my clunker (rusty but reliable!) before I get an Aveo.

Wow, way to necro a thread from 09! I used to use a clutchless upshift when I would do track days on my Ducati but it made sense there. You just put upward pressure on the shift lever and back off the throttle a touch. It shifted then give it the beans again. It saved tons of time when tenth of a second counted. Down shifts are another story, never clutchless but the slipper clutch meant you just grab the clutch lever, bang the shift lever down to where you need it and dump the clutch. The slipper matched the revs with no wheel hop at all. It was not uncommon to go from 5th to 2nd for a hairpin at the end of a straight. The Duc would go faster in 3rd than the Aveo could top out at so I don't drive it that hard.
