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.

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.

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).

TRD clutch is in, no more shudder in 1st. I'll have to check out reverse and see if it's gone or reduced.
I am getting a bit of a squeaking noise in 1st. I talked to the technician that did the install, and he said there would be a 100 mile break-in period, and that the noise should go away. I'll be sure to hold them to that.

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

This shudder (chatter) seems to be a design flaw just like the "Big Foot Mod" and the imprecise throttle tip-in that causes rough shifts and stalling.
I drove a 5-speed xB for 50K miles before trading for my Yaris and it has been a nightmare with the Yaris. The xB was nearly flawless at 50K and I never had clutch chatter or shifting problems. And yes, first gear has a synchro on it. It just doesn't work worth a damn. |

UPDATE: Just a bit over a month since the clutch was installed, and I've noticed some fluid on the ground under the car.
Got under there, and it looks like the transmission case is leaking some oil. My guess is the tech got a bad seal. Back to the dealership on Thursday ...

Happens to me, my car just rolled over 10K miles. I've noticed it since like 4,000 miles, I drive like you, I try to start with as low RPMs as possible. I thought I was skidding the tires at first but it's happened on flat, dry, gravel-free surfaces. I do not feel any erratic resistance in the clutch, just the lurching of the car. Wonder what's causing it.

Sorry for bringing this thread back to life but is there a fix for this? I've been driving manual tranny since 1992 and this is the worse 1st and reverse gear. My 1976 corolla had better 1st/reverse than this Yaris. Please advise. Thanks!

A permanent fix would be getting a better aftermarket clutch.
Other than that bleeding the slave cylinder helps but it only last a few weeks. |
