Just bought a 2008 Hatchback Manual Tranny and it shifts really strange

Thanks for the info. I know in some cars you have to remove the engine, or at least raise it to be able to remove the transmission for clutch replacement.

On another note, my dad replaced the clutch in his VW beetle and had the entire transmission on his chest. underneath the car. It was a sight to see. I think all repairs on a beetle can be done with a socket set and a screwdriver.

The 2 cylinder air cooled engine? It doesn't take much to get that engine going. Lol

No feel, and the fact that the torque/intertia phase is too short coupled with the laggy throttle response equals the following experience: disengage clutch, shift into gear, begin engaging clutch, no sense of clutch engagement, clutch begins to engage but very quickly, give throttle to compensate, throttle response delayed, car begins to bog, throttle overcompensates, clutch judders and finally engages abruptly with slight shock.

You're probably looking at $700-1000 depending on where you take it and, if you need a new flywheel, it may cost another $300-400 on top. Not cheap, but rarely required and the reliability of the Yaris otherwise makes up for it.


I don't think anyone has actually touched on why the Yaris clutch sucks so bad. The reason is because there is absolutely no feel right? When wearing workboots I literally cannot feel the engagement point of the clutch because the pedal is so light. The main reason for this is the diaphragm spring on the pressure plate are very light. This is the essentially the part that your foot is pushing against (after a bit of hydraulics and leverage). So get a clutch with heavier diaphragm springs would make a big difference. As mentioned before, performance clutches feel better because they have heavy diaphragm springs to give better clamping force on the clutch disc. I have not tried one in a Yaris yet, but it should make a world of difference in pedal feel. A performance clutch is probably a very good idea for people who just want better clutch feel than OE.

That being said, I don't know that I want one in my car I've learned from past experiences that clutches are cheap compared to transmissions. From much higher horsepower cars than the Yaris, but I typically run weak clutches in my cars so that the clutch breaks before the transmission etc. Clutches are cheap compared to hard parts.

Cheers.

Also, this is an excellent video on how clutches work: https://www.youtube.com/watch?v=pqF-aBtTBnY

Does the tranny drop out from under the car or do you pull it from the top up?

Aircooled Beetle always had a flat four cylinder engine, never just two.

Underneath. You have to remove the subframe as well. At least I'll be able to put my larger front swaybar on finally....

I've learned, especially when stopped at a busy intersection on a hill, to turn the radio down. It helps me anyway as the thing is so quiet and the clutch action so tricky, or maybe it's that electronic throttle, or all of the above..... No big deal, a small price to pay for such a great little rig, I've gotten used to it. Driving it the short distance from my place to the nearby ski area while wearing my snowboarding boots gets real interesting, but still workable.

*sigh*.....pretty much no such thing in Texas (unless you live in or near El Paso), but this is still a great state in so many other ways .

EXACCCTTLYY...what I do! I stalled mine a few times in bad traffic. Once in San Francisco. Not good.
I am getting the hang of it. Slowly

Good advice. I often like the radio off when I'm driving. I like to listen to the sound of the engine. Usually around town. Interstate I use the radio or Bluetooth.

Just an update: I installed a LUK clutch recently. The pedal feel is the same as OE, with maybe 10% more effort required. The OE clutch is SERIOUSLY heavy-duty. It's no wonder they last so long. The trade-off is that they are heavy. The LUK is much lighter and gives a small, but noticeable, increase in acceleration. It would probably only last half as long as an OE clutch with normal driving though.

I was thinking of trying a smaller slave cylinder bore to improve the pedal feel. Toyota has used this two-bolt style for a long time so it may be possible to find one that bolts on. The smaller bore will make the pedal effort higher, and may allow more feel. Trade-off is that it will release at a higher point in the pedal.


I also had two captivated nuts for the subframe bolts spin, so had to drill holes in my floor to fix it

My old manual 535 was amazing even with me being a beginner to a manual trans car. What kind of throttle linkage (hopefully the right term)? There's been quite a learning curve to getting used to working the gas and clutch.

that might be interesting. If you do that modification let us know

Looking into it, the Yaris slave already has a very small bore. I doubt we will find one smaller. So a larger master that bolts up is the next bet, which seems unlikely. I'll keep looking.
