Clutch shudder when setting off in 1st gear

[mick.wheelz]

My yaris has over 100,000km (~60,000mi) on it now, and does this in 1st when it is cold... only if you let it out either too fast, or dont give it enough gas.

The car is on its orig. clutch, so i doubt it causes any long term reliability issues.

i find the same problem. i have learned to master 1st but revers....fml man, i back up on my drive way (up hill) and unless i'm riding clutch hard and RPMs atleast 1500 or doing 40km in reverse it looks, feels and sounds very bad.

also with the gearing ratio i find its awkward to slow down and take off again but not stop. too fast for 1st, too slow for second...... any advice? (other then learn how to drive, lol)

I definitely find this to be evident! I usually just shift into second and give gas but the car really doesn't want to go into 1st gear unless stopped.

i find it makes right turns very awkward and red lights that magically turn green a nightmare.... almost feels like its gonna stall. and today i decided to try and ride the clutch a bit.....this will not fix anything, make alot of noise then bounce. lol. guess we gonna have to live with it or change the gears.....

I sometimes double clutch to get into 1st gear easier... i.e. clutch out, raise RPMs 500-1000 higher than idle, clutch in and shift into 1st gear at a slow rolling speed. This is all at below 5mph speeds of course.

[yaris2010RS]

so u release clutch then rev a bit to get it aprox 2000RPM and then depress clutch and 1st? tomorrow on my way to school will definatly give it a shot.... lol

[yaris2010RS]

something i noticed on my way home today tring to glide down a hill, possibally completly off topic but still has to do with clutch. i was driving down the road at crusing speed 100 KM/H and around 2,500RPM, so i depressed the clutch shifted to neutrel (no gear) and let go of clutch. i watched my RPMs drop to 1,000 then 500(my normal idle) then jump up to 1,500 and kept bouncing from 500 - 1,500. this only happens if i'm off the clutch and in no gear, if i'm holding clutch it wont bounce around. i took a video so if u dont exactly follow what i'm saying follow link

i'm sorry, its very bad quality and uber long, lol, i started messing around after a while, lol. and since my right hand (shifter hand) was holding phone made for a very bad experience. lol

Less than that: 1,000 or 1,500 rpm. You'll know it's right when you can shift into first with zero resistance :)

I don't put mine in neutral at that high of a speed, but from 40mph (60kmh) my revs will bob once or twice, but not as many times as yours did in the video. I don't worry about it, at all.

This isn't a defect or an issue. It is "shuddering" because the first and revers gears don't have syncros. The yaris motor has almost no will to live so in first gear you have to get the RPM's up a little and feather the clutch properly. Problem solved.

Wow ... more updates later.

Nice. Maybe I should take mine in and claim I am having "shudder" issues

lol, wasn't really too worried about it and probably not gonna do it too often either. lol. just one day on the highway going down hill and decided to try it.
jsut wondering if it has to do with the constant revving at idle which i do find very annoying.

my friend sudgested it has to do with cold wind coming in and the engine trying to keep going or resistance the tranny is putting it in even in no gear.

[yaris2010RS]

and i gotta take blueberry in soon too...... after the recent toyota recalls i find my clutch can do the same..... happened to me a few times...... not too much of an issue but still

[tk-421]

I'm starting to have shudder issues myself... The weird part is that I have already swapped my clutch once (ACT Stage 1)... Starting to wonder if the tranny fluid is leaking...

Another weird thing is that sometimes I will get a bit of grinding when I downshift from 3rd to 2nd gear (while engine-braking), even if my clutch is completely engaged (foot all the way down).

[yaris2010RS]

I am personally beginning to question the hydraulic fluid....

Someone correct me if I'm wrong ...

I'd like to know this as well...reverse probably doesn't have syncros.

However, a lack of syncros would not cause a shudder.

That's just what I have heard You have to bring it damn near to a stop to pop into first wuithout a rough shift.

it probably the "#$#% drive by wire system.thats the only thing that pisses me off with this car.
